Financial Analysis for Operations Management Decisions - Summary for Revision


Financial analysis tools and concepts are important for OM.

These tools include the types of costs, activity-based costing, risk, and expected value, and depreciation for more periodic operating decisions. When the focus of OM decisions is capital investment, issues of cost-of-capital calculations and methods of ranking investment proposals are important.


Fixed costs are any expenses that remain constant regardless of the level of output of production.

Variable costs, conversely, vary directly with changes in output levels.

Sunk costs are past expenses or investments that have no salvage value and therefore should not be taken into account when considering investment alternatives.

Opportunity costs are the benefits lost that result from choosing one action over another action.

Avoidable costs are expenses not incurred if an investment is made but that must be incurred if the investment is not made. Avoidable costs becomes the cost savings, for the proposed projects and hence enter into financial or economic analysis as positive cash flows against the negative cash flows due to investment in the project.

Expected value is the sum of expected outcomes multiplied by the probability of their occurrence. Expected values result because there is risk inherent in any investment decision.


The life of a machine or other income-producing assets is estimated and for accounting purposes, the asset is depreciated over this period. Depreciation is a method for allocating costs of capital equipment. Methods of depreciation include the straight-line method, the sum-of-the-years' digits method, the declining-balance method, the double-declining -balance method, and the depreciation-by-use method.

Activity based costing is an important accounting concept for OM and it is the practice of allocating overhead to better reflect actual proportions of overhead consumed by the production activity. Causal factors or cost drivers are identified and are used as the basis for overhead allocation as direct labor is not the best basis for allocating all overheads.

When choosing among investment proposals, investments are generally ranked according to the return they yield in excess of their cost of capital. Investment decisions can include the purchase of new equipment or facilities, replacement of existing equipment or facilities, make-or-buy decisions, lease-or-buy decisions, temporary shutdowns or plant abandonment decisions, or the addition or elimination of a product or product line.

Other financial decisions include determine the cost of capital, tax issues, and interest rate effects on OM decisions. Ways to rank investments include the net present value method, payback period, and the internal rate of return.

Costs relevant to aggregate production planning include basic production costs to costs associated with changes in the production rate, inventory holding costs, and backordering costs.

Important Operations Decisions Requiring Financial Analysis


1. Purchase of new equipment or Facilities
2. Replacement of existing equipment or facilities
3. Make or buy decisions (components)
4. Lease or buy decisions (equipment)
5. Temporary shutdowns or total plant closure decisions
6. Addition or elimination of a product or product line

Manufacturing execution systems do scheduling.

Work Center


Work centers are areas in a business in which productive resources are organized and work is completed. It may be a single machine, a group of machines, or an area where a particular type of work is done. The work centers can be organized in a variety of ways including by function in a job-shop configuration; or by product in a flow, assembly line, or group-technology-cell configuration.


Scheduling and controlling functions of an operation are critical. The functions must be performed beginning with allocating orders, equipment, and personnel to work centers or the specified locations for short-run capacity planning. Next is the determination of the sequence of order performance or establishing job priorities. Initiating the scheduled work or dispatching of orders is followed by shop-floor control.


Loading - Infinite loading or Finite loading

A characteristic that distinguishes one scheduling system from another is how capacity is considered in determining the schedule. The scheduling systems can use infinite loading or finite loading.

Infinite loading occurs when work is assigned to a work center simply based on what is needed over time.

Finite loading actually schedules in detail each resource using the setup and run time required for each order.



Another characteristic, that distinguishes scheduling systems, is whether the schedule is generated forward or backward in time.

Processes can be machine limited or labor limited. Determining the sequence of orders and establishing job priorities are critical as is dispatching orders.

Shop floor control

Shop floor control is necessary to review job status and expediting late and/or critical orders when necessary. The schedule must be revised as necessary to reflect changes in order status.


Various priority rules work to satisfy job arrival patterns, the number and variety of machines in the manufacturing facility, the ratio of workers to machines in the shop, the flow pattern of jobs through the shop, the priority rules for allocating jobs to machines, and schedule evaluation criteria. Priority rules for allocating jobs to machines can use a variety of methods.



The objectives of work-center scheduling are to meet customer due dates, minimize lead-time, minimize set-up time, minimize work in process inventory, and maximize machine or labor utilization.




Role of Simulation


In manufacturing job shops, scheduling relies heavily on simulation to estimate the flow of work through the system to determine bottlenecks and adjust job priorities. Software packages are available to do this. In services, the focus is typically on employee scheduling using mathematical tools that can be used to set work schedules in light of expected customer demand.

They use one or more of four distinct strategies:
They leverage data flows to integrate closely with their supply chain partners;
they optimize customer value across the whole chain, not just their part of it;
they cooperate with suppliers to rapidly improve their manufacturing processes; and
they harness their technical capabilities to offer a high degree of product customization for their customers. In short, they work with partners to manufacture solutions for other partners.

Material Requirements Planning - Review Notes for Chase et al. Book Chapter

Summary for Revision

When demand is dependent on multiple materials, managers use a concept known as materials requirements planning, or MRP, to determine demand for lower level items. MRP is a logical approach to determine the number of parts, components, and material needed to produce each end item. It also provides the time schedule specifying when each of these materials, parts, and components should be ordered or produced.

MRP has grown from planning materials to also planning for other organizational resources needed.



Bill of Materials gives the hierarchical details of finished product, main assemblies, sub assemblies, components and materials of a product.



From an organization's aggregate plan, the master production plan (MPS) is developed. The MPS is the time-phased plan specifying how many and when the firm plans to build each specific end item. Further down the MPS process is the MRP, which calculates and schedules all of the raw materials, parts, and supplies needed for production.

If customers give advance orders, management must specify a time fence, or period of time in which the customer can make changes in their order. Once this time has passed, the order becomes fixed. The MRP uses this fixed plan to create schedules to identify the parts and materials required to produce end items, the exact numbers needed, and the dates when orders for these materials should be released and be received or completed within the production cycle.


Today, computerized inventory systems for MRP control inventory levels, assign operating priorities for items, and plan capacity to load the production system. The goal of MRP is to get the correct materials to the right place at the right time.

The objectives of inventory management under an MRP system are to improve customer service, minimize inventory investment, and maximize production operating efficiency. The MRP interacts with the master production schedule, the bills of material file, and the inventory records file. Product demand data for MRP systems comes from two sources -- from customers who have placed firm orders and from forecasted or anticipated demand.


The bill of materials (BOM) file contains the complete product description listing the materials, parts, and components as well as the sequences in which the product is created. MRP outputs can take a variety of forms and can be classified as primary and secondary output reports. Capacity constraints can be determined using capacity requirements planning. An MRP program with a capacity requirements planning module allows rescheduling to try to level capacity through either backward or forward scheduling. The master schedule will try to level out the load so that requirements for work centers remain within the available capacity.

MRP II has expanded the role of MRP to include planning for staffing, facilities, and tools. Called manufacturing resource planning, it can plan and monitor all the resources of a manufacturing firm including manufacturing, marketing, finance, and engineering within a closed-loop system.

JIT is best suited to repetitive manufacturing. MRP is used in everything from custom job shops to assembly line production. The term flow manufacturing is now being used by many software vendors to describe new software modules that combine MRP and JIT logic.

MRP applications have many uses even in service organizations. But so far only a few service organizations have developed or implemented MRP. Many believe that it is a manufacturing tool.

What is Operational Excellence in Manufacturing and Supply Chain?


Product quality, productivity and customer retention are the pillars of operational excellence. They  are critical to profitable manufacturing concerns. Operational excellence has emerged as the key management initiative to sustainable revenue and business growth.

What is operational excellence?

As defined by Michael Treacy and Fred Wiersema in a seminal Harvard Business Review article, “Companies pursuing operational excellence are indefatigable in seeking ways to minimize overhead costs, to eliminate intermediate production steps, to reduce transaction and other ‘friction’ costs and to optimize business processes across functional and organizational boundaries.”

Operational excellence is ultimately about delighting your customers, setting a new standard of performance in your industry and becoming the preferred supplier in your industry.  As a preferred supplier, you grow revenue with existing customers and  attract business away from your competition.

Operations is the delivery mechanism of the manufacturing enterprise, providing what the business sells and how that product gets to market. It is an engine driving the work in purchasing, production, distribution, logistics and inventory management. That engine depends on input from the front line of the business—sales, marketing and is supported by finance.

To connect processes with performance goals, companies need business intelligence (BI) capabilities, including metrics, key performance indicators (KPIs), dashboards and advanced reporting. With the right BI solution, manufacturers can gain crucial visibility into performance and ensure Operations is functioning at peak levels.


You can get a continuous view into key areas, can gain the ability to see problems as they happen,
can see trends developing, which allows you to take proactive action to prevent problems in real time or  before they happen. This means you can solve problems quickly and guarantee they have a minimal effect on your business. It helps to prevent losses and to improve revenues by identification of new, potentially profitable business opportunities.

Aggregate Sales and Operations Planning - Review Notes

Aggregate operations planning involves translating annual and quarterly business plans into broad labor and output plans for the intermediate term of 6 to 18 months. Its objective is to minimize the cost of resources required to meet demand over that period. It takes a broad view of the organization and attempts to match the demand for the firm's products with its ability to supply these products at a minimum cost.

Long-range planning is done once a year, focusing on a multi-year horizon while medium-range planning covers 6 to 18 months into the future. Short-range plans cover one day to six months in weekly increments. The master production schedule generates the amounts and dates for the production of end products and is fixed in the short run.

Rough-cut capacity planning verifies that the scheduled production is possible given capacity constraints of facilities, equipment, and labor. Materials requirements planning takes the end product requirements from the MPS and breaks them down into their component parts and subassemblies to create a material plan.The final assembly schedule provides the operations required to put the product in its final form. Production activity control focuses on scheduling and shop floor control activities.

Aggregate production planning varies from company to company. Strategies of production planning include maintaining a stable work force working at a constant rate, using a stable work force with variable work hours, or using a chase strategy where workers are hired or laid off as the demand varies. In addition, managers may choose to subcontract some portion of production.

Costs relevant to aggregate production planning include basic production costs to costs associated with changes in the production rate, inventory holding costs, and backordering costs.

To receive funding, operations managers are generally required to submit annual, and sometimes quarterly budget requests.

Aggregate operations planning links the corporate strategic plan and the capacity plans into broad categories of work-force size, inventory quantity, and production levels. It does not do detailed planning.

In the case of aggregate planning based on decision rules, once decision rules for production planning have been selected, it is important for management to maintain them. Historical data and simulations should be used to select an optimal decision rule.

Yield management allocates the right type of capacity to the right type of customer at the right price and time to maximize revenue or yield and it can make demand more predictable which is important to aggregate planning.

Inventory Control - Review Notes for Chase et al. Book Chapter

Inventory is the stock of any item or resource used in an organization.

Inventory can exist as raw materials, finished products, components parts, supplies, and work-in process.

Organizations keep inventory for a number of reasons including to maintain independence of operations, to meet variation in product demand, to allow flexibility in production scheduling, to provide a safeguard for variation in raw material delivery time, and to take advantage of economic purchase order size.

Costs associated with inventory include holding or carrying costs, setup or ordering costs, and shortage or stockout costs. Inventory management has the responsibility to optimize these costs along with the benefits that accrue due to inventories.

Independent demand items are unrelated to each other and thus needed quantities for these independent items must be determined separately. For dependent demand items, the demand for one item is a direct result of the need for other items. Component parts demand, for example, is dependent on the demand for the final product. If the schedule of finished product delivery is finalized, one can arrive at the demand for component parts in various time buckets.
Inventory planning and ordering systems can be modeled as fixed-order quantity or fixed-time period. In the fixed-order quantity model, the same amount of inventory is replenished in each order. The assumptions include: demand is known, constant, and uniform throughout a period. Lead time is constant and the price per unit and ordering costs are constant. But the model is applied to situations with varying annual as well as periodic demand


In a fixed-time period system, inventory is counted at fixed time intervals and orders are placed on a periodic basis. This model is desirable in situations when vendors make routine visits to customers and take orders for their complete line of products or when buyers want to combine orders to save on transportation costs.
Organizations must make decisions about the amount of safety stock to maintain for protection against stockouts. The safety stock ensures a firm's desired service level will be met.

The quantity-discount inventory model applies when the cost of an item varies with the order size. This model, as in all inventory models, computes an economic order quantity (EOQ) to minimize order costs and holding costs.


ABC analysis is a planning and control technique. The highest dollar volume items, or "A" items, are given the most attention in planning and the most rigorous cycle counting and attention for inventory control.

Because many firms, including services, may have large inventory investments, inventory reductions will lead to reduced costs. The managers of Toyota Motors developed their production planning methods with a view to reduce inventory and found that it required cutting set up times. Hence reduction in set up times was pursued, they reduced 8 hours of set up time to 8 minutes and further to three minutes. They also found that they needed to reduce defects and hence took up quality improvement activity in production processes. The succeeded in achieving low inventories that gave them savings in costs associated with inventory and also reduced their quality costs and set up costs. Overall they got lower cost of production hence became globally competitive.

Two examples where inventory control is used on in service companies are a department store and an automobile service agency.

The IBM® Cognos® 8 Business Intelligence Solution for Operations Excellence



The IBM® Cognos® 8 Business Intelligence solution can make your entire supply chain, all your operations and your entire enterprise intelligent — by delivering the global visibility that is the key to your success in your business endeavor.

IBM Cognos 8 BI can track a number of key metrics that are the critical factors in the success of your Operations, for example:

Increased throughput.
Reduced manufacturing costs.
Shortened lead times.
Reduced backlog.
Improved quality performance.
Reduced reject rate.
Reduced scrap levels.
Reduced line downtime.


Linking strategic metrics developed by executives down to operational metrics on the plant floor


Most Operations personnel working in a large plant may have little idea of the official corporate strategy, or how they can best contribute to that strategy. Similarly, visibility of operational performance between the corporate and business levels is often very poor.


A scorecarding system, which may be based on the Balanced Scorecard approach or on the SCOR (Supply Chain Operations Reference) model created by the Supply Chain Council, can be very effective in making performance visible, thereby forcing an emphasis on visibility of performance targets and actual performance and encouraging an environment of increased accountability.

Manufacturers that have undertaken the  task of defining their KPIs are well positioned to adopt scorecarding technology. They will be very useful if these have been defined across multiple plants within a business unit. These KPIs should be hierarchically defined, so that business users can “drill down” into areas of poor performance to understand root causes. Web-based scorecards and dashboards
ensure maximum visibility, access and use.

Linking strategic metrics developed by executives down to operational metrics on the plant floor drives business and operational alignment, and the result is operational excellence.


Procurement Excellence

 The purchasing organization and your suppliers’ performance are quantified and tracked with KPIs
that measure quality and cost (including comparisons to alternate sources), delivery and order or requisition placement.

Supplier scorecards enable continuous, timely measurement against consistent standards for all suppliers.
With consolidated procurement information, you are better able to leverage your company’s purchasing power. You can identify suppliers that offer the same materials or services, and rapidly evaluate their offerings against the same standards.

With the ability to monitor all your suppliers, you can leverage your knowledge to improve supplier responsiveness and the efficiency of your supply chain, and you can gather data that will help you make the most profitable decisions when negotiating future procurement contracts. In addition, you can share information, such as supplier performance data, with suppliers via an extranet, so they know when corrective action is required or when standards have not been met.

Also, having aggregate information on demand, including inventory, supply, supplier performance, etc., allows for quicker and better purchasing decisions leading to a more proactive purchasing organization. With better information in hand, you can consolidate and optimize your suppliers and leverage your buying power, which means a potential for better terms and lower supply costs.

Production Excellence

IBM Cognos BI software offers visibility across all plants, lines and shifts, allowing you to monitor performance trends and to identify, isolate and analyze the source and impact of problems, whether product defects or production anomalies. With the ability to make accurate comparisons, for example, between facilities and shifts, you can discover lags and other problems that had previously gone unnoticed. You
can also identify trends in quality, efficiency or throughput, and make proactive decisions based on this insight.

Similarly, the solution makes available allows you to analyze the cost of failures: scrapped production, customer returns and other quality-related problems; downtime; as well as costs for specific
overhead items such as re-engineering and equipment upgrades.

This intelligence can be used to help capitalize on success, to analyze savings created by new efficiencies or to help understand how to repeat an event that improved quality or throughput. It also offers the benefit of being able to share production performance information with staff, including comparisons across
locations, over time, measurement against production standards, etc.


Inventory Management Excellence

The solution opens visibility into the entire inventory: the levels and locations of all assets at any point in time, their worth, their depletion rates, their use; who supplied them, who uses them; what is spoiled, obsolete or surplus; what alternative items are available. With inventory accurately quantified and tracked
across the company and its partners, and with changes measured against common standards, such as minimum or age thresholds, you will know at all times what you have, where it is and how long it will last.

Just-in-Time and Lean Systems - Review Notes of Chase et al. Book Chapter

Just-in-time or JIT is an integrated set of activities designed to achieve high-volume production using minimal inventories of raw materials, work in process, and finished goods. Parts arrive at the next workstation "just in time" and are completed and move through the operation quickly. Nothing is produced until it is needed later in the assembly line. The consumer expresses a need for a product, and "pulls" demand through the production system.

In Japan, JIT has been used to isolate the elements of waste in an organization. The Japanese practice a great respect for people and depend on the personnel to identify and eliminate sources of waste, excess, and inefficiency. The basic elements of JIT are a focused factory with networks following the strategy of reducing waste, the use of group technology or teams for problem-solving, quality at the source so no time and energy and materials are wasted on less than perfect quality products, uniform plant loading, Kanban production control systems, and empowerment of workforce.

While North American systems have modified JIT, the techniques can be used in layouts and design flows as well as in job shops. JIT has also merged in theory and practice with TQC, or building quality into the process. JIT works at its best when only good-quality products are pulled through the system and no "just-in-case" extra inventory is needed.

JIT requires a stable schedule over a lengthy time horizon. Along, with customers and employees, who are key components of the JIT system, vendors are also important to the process.

JIT is also applicable to service industries. Successful service applications include organizing problem-solving groups, upgrading housekeeping and quality, clarifying process flows, eliminating unnecessary activities, and developing supplier networks among others.


JIT is a powerful tool for reducing inventory and improving production and service operations. Management support, commitment, and training to continuing JIT progress are essential to success.

Industrial engineering and JIT

I define industrial engineering as human effort engineering and systems efficiency engineering. Functional design of a system is not the core focus of industrial engineers. There are various disciplines of engineering for functional design. Each of the designs created by functional engineers can be evaluated by industrial engineers for efficiency audit and improvement. JIT may have started as an efficiency improvement initiative. But now JIT could have become a functional discipline. Industrial engineers still have the role to audit efficiency of JIT systems and improve their efficiency further with the tools of efficiency currently in their tool box and tools which may come out subsequently.

Chapter Topics


Lean Logic


Lean production is an integrated set of activities designed to achieve production using minimal invetories of raw materials, work-in-progress, and finished goods. Parts arrive at the next workstation "just in time" and are completed and move through the process quickly. Lean is also based on the logic that nothing will be produced until it is needed.


The Toyota Production System


Toyota production system was created as the chief of Toyota told his team, we have to become price competitive to survive American imports. Hence we have to become lower cost and more productivity company.

Elimination of waste, improvement of efficiency, an industrial engineering slogan became the theme of Toyota Managers. Taichi Ohno, a production manager is credited for the development of TPS. Along with the elimination of waste, respect for people is also highlighted in Toyota culture. People are given importance in the system and they are asked to learn new skills and focus on productivity and continuously improve productivity.

The book gives a Toyota President, Fujio Cho's statement. "We must use the minimum amount of equipment, materials, parts, and workers (working time) which are absolutely essential to production." So the emphasis on finding optimal or ideal requirement of resources and controlling the process in such a way that production is achieved with those optimal resources.  But waste occurs in production processes and more resources are consumed by production systems. Seven types of wastes were described in TPS which have to measured and eliminated. 1. Waste from overproduction  2. Waiting time 3. Unnecessary transportation  4. Inventory  5. Unnecessary processing  6. Unnecessary human motionand 7. Defects and reworking.

MIT Team who studied TPS and developed theory of lean systems, recommended value stream mapping as the major visual tool to identify waiting time and inventory. It provided a box structure to various show waste at various work centers and operations in a process.

Forecasting - Operations Management Review Notes

Forecasts are vital to every business organization and for every significant management decision. While a forecast is never perfect due to the dynamic nature of the external business environment, it is beneficial for all levels of functional planning, strategic planning, and budgetary planning. Decision-makers use forecasts to make many important decisions regarding the future direction of the organization.

Forecasting techniques and models can be both qualitative and quantitative and their level of sophistication depends on the type of information and the impact of the decision. The forecasting model a firm should adopt depends on several factors, including forecasting time horizon, data availability, accuracy required, size of the forecasting budget, and availability of qualified personnel.

Demand management exists to coordinate and control all sources of demand so the productive system can be used efficiently and the product delivered on time. Demand can be either dependent on the demand for other products or services, or independent because it cannot be derived directly from that of other products.

Forecasting can be classified into four basic types:
Qualitative,
Time series analysis,
Causal relationships, and
Simulation.


Qualitative techniques in forecasting can include grass roots forecasting, market research, panel consensus, historical analogy, and the Delphi method.  Qualitative forecasting is based on surveying and finding out intentions of people regarding use and purchase of a product. Similarly it is finding the opinion and forecast of sales persons.


Time series forecasting models try to predict the future based on past data. A simple moving average forecast is used when the demand for a product or service is constant without any seasonal variations. A weighted moving average forecast varies the weights, given a particular factor and is thus able to vary the effects between current and past data.

Exponential smoothing improves on the simple and weighted moving average forecast as it considers the more recent data points to be more important. To correct for any upward or downward trend in data collected over time periods to smoothing constants are used. Alpha is the smoothing constant, while delta reduces the impact of the error that occurs between the actual and the forecast.

Forecast errors are the difference between the forecast value and what actually occurred. All forecasts contain some degree of error, however it is important to distinguish between sources of error and measurement of error. Sources of error are random errors and bias. Various measurements exist to describe the degree of error in a forecast. Bias errors occur when a mistake is made, i.e., not including the correct variable or shifting the seasonal demand. Random errors cannot be detected, they occur normally.

A tracking signal indicates whether the forecast average is keeping pace with any movement changes in demand. The MAD or the mean absolute deviation also is a simple and useful tool in obtaining tracking signals. A more sophisticated forecasting tool to define the functional relationship between two or more correlated variables is linear regression. This can be used to predict one variable given the value for another. It is useful for shorter time periods as it assumes a linear relationship between variables.

Causal relationship forecasting attempts to determine the occurrence of one event based on the occurrence of another event.

Focus forecasting tries several rules that seem logical and easy to understand to project past data into the future.

Today many computer forecasting programs are available to easily forecast variables. When making long-term decisions based on future forecasts, great care should be taken to develop the forecast. Likewise, multiple approaches to forecasting should be used.

Forecasting needs to be done in various areas of management like financial management, marketing management, personnel management etc. and the same techniques discussed in this article are used in those disciplines also.

Forecasting is an important activity in security analysis.

Supply-Chain Strategy - Review Notes

The idea of supply-chain management is to apply a total systems approach to managing the entire flow of information, materials, and services from raw-materials suppliers through factories and warehouses to the end customer. The term supply chain comes from a picture of how organizations are linked together as viewed from a particular company.


The focus is on those core activities that a business must operate each day to meet demand. The topic is popular because many companies are achieving competitive advantage by the way they configure and manage their supply chain operations. Dell Computer is a good example of effective supply chain management.



Because inventory at each stage of an operation ties up money, it is important that the operations at each stage are synchronized to minimize the size of buffer inventories. The efficiency of the supply chain can be measured based on the size of the inventory investment in the supply chain. Key measures to evaluate supply chain efficiency are inventory turnover and weeks-of-supply. Other measures include the cost of goods sold and the average aggregate inventory value.

Inventory turnover =  Cost of goods sold/Average aggregate inventory value

Variability within the supply chain magnifies as we move from the customer to the producer in the supply chain. This bullwhip effect indicates a lack of synchronization among supply chain members. Programs like continuous replenishment smooth the flow of materials through the supply chain.

Other supply chain issues occur because of the length of the product life cycle, demand predictability, product variety, and market standards for lead times and service. Products may be either functional staples or primarily innovative and require different management methods.

Functional products are staples that people buy in a wide range of retail outlets.  Typically, they do not change much over time, have low profit margins, stable predictable demand and long life cycles.  Innovative products, on the other hand, give customers new benefits and hence provide additional reasons to buy.  Fashionable clothes is one example of innovative products. Smart phone and tablet computers are examples of innovative products of the recent period.  Innovative products have short life cycles, high profit margins, and volatile demand.


 Lee argued that on the supply side also there are stable supply processes and evolving supply processes. Based on these two classification four supply chain management strategies were identified.


Efficient supply chains
Risk-hedging supply chains
Responsive supply chains
Agile supply chains

Efficient supply chains are designed to minimize cost that requires high utilization, minimizing inventory, and selecting vendors based primarily on cost and quality, and designing products that are produced at minimum cost.

Market-responsive supply chains are designed to minimize lead time to respond to unpredictable demand, thus minimizing stockout costs and obsolete inventory costs.

Risk sharing supply chains are those that share resources so that risks in the supply chain can be shared.
Agile are those supply chains that are flexible while still sharing risks of shortages across the supply chain.  Generally, these supply chains carry excess capacity and higher buffer stocks.  Vendor in responsive supply chains would be selected for speed, flexibility, and quality.


Outsourcing


Outsourcing is moving some of a firm's internal activities and decision responsibility to outside providers. Companies have a variety of reasons for outsourcing but primarily the reasons are to reduce costs and create a competitive advantage. Full list adopted from the book Strategic Outsourcing by Maurice F. Greaver II. was provided in the book (Chase et al.)  One popular area to outsource is logistics. In determining the shipping mode for an item a key variable is the value density or value per unit of weight.

Design for Logistics

Given the emphasis on minimizing inventory and handling in efficient supply chains, design of the components and materials can be evaluated from their each of storing, picking and handling. Hence design for logistics is also to be incorporated in design process.

Global Sourcing

With the communist bloc of countries now into free trade system, a truly global supply chain system can be created.

Mass Customization

Three principles of mass customization are given in the book.

1. A product should be designed so it consists of independent modules that can be assembled into different forms of the product easily and inexpensively.

2. Manufacturing and service processes should be designed so that they consist of independent modules that can be moved or rearranged easily to support different distribution network designs.

3. The supply network - the positioning of inventory and the location, number, and structure of service, manufacturing, and distribution facilities - should be designed to provide two capabilities. First, it must be able to supply the basic product to the facilities performing customization in a cost-effective manner. Second, it must have the flexibility and the responsiveness to take individual customers' orders and deliver the finished, customized good quickly.

This book introduces the fundamental principles of understanding business requirements to apply enterprise resource planning (ERP) in order to meet business needs. The book also helps readers understand the usage of ERP for monitoring and controlling business processes, while providing practical oriented solutions to the design and implementation of ERP. Using the provided framework, a business can decide to provide more value at lower cost which increases its competitive advantage. This should be an ideal reference for executives, researchers and consultants in project management of ERP. ERP can be considered to be an integrated package of business process. The scope of ERP determines the extent of automation of business process. For example if ERP covers Human Resource (HR) and finance business processes only, then business process related HR and finance are automated. Typically business process that are automated in HR and finance employee entry and exist process, allocation of employee ID, payroll, processing , income tax planning and actual deduction etc. There is seamless flow of employee data and information is available at an effectively faster rate to take appropriate decision. As custom demand increases, there is a need to meet the changing scenario with speed and efficiency. While there is a need to increase productivity, there is also a need to reduce cost of operation. The repetitive business processes can be handled effectively by automating them and freeing human resources for meeting other uncertainties. These automations not only should be done for each department, but also should cut across different departments. Thus there is a need for automating business processes at enterprise level. This enterprise level automation started with MRP, then MRP II, ERP and then finally open source ERP have taken centre stage. Out of the standard products available in the market, an organization can chose an ERP product for implementation, depending on the features available and the total cost of ownership (TCO). This comparison helps an organization to choose the product that best suits the needs for the organization. Enterprise Resource Planning: Fundamentals of Design and Implementation highlights these concepts while discusses different good practices to design and implement ERP.

This book examines the modules/elements required before implementing knowledge management solutions in typical manufacturing and service industry. The objective is to develop a framework, design and model suitable for all requirements and a strategy to properly implement. Related case studies from organizations are included, with the results provided to use as a solution to problems experienced when implementing knowledge management in the industry.Implementing a knowledge management system can be complex and dynamic, no matter how well planned and developed. Inevitably a degree of organizational inertia is focused on the current state rather than the new. Within an enterprise, personal and group involvement and interests process status and technology landscape can deflect the commitment needed to successfully implement such a system. Cumulative evidence from past research in knowledge management suggests that effective implementation of KM solution in any organization requires a robust designs and models for various critical elements of process, people and technology. Using the techniques provided in this book, readers should be able to design knowledge management strategies, to align objectives of the KM initiatives with their business goals.

Learning Curves - Review Notes

Learning curves are important in a variety of business applications, especially manufacturing. The learning curve theory is a relationship between unit production time and the cumulative number of units produced. As individuals or organizations collectively repeat a particular process, they gain skill or efficiency from their experience and production time improvements result.

The learning curve theory is based on three assumptions: (1) the amount of time required to complete a given task or unit of a product will be less each time the task is undertaken, (2) the unit time will decrease at a decreasing rate, and (3) the reduction in time will follow a predictable pattern. This is often referred to as "practice makes perfect."

If production has been in progress for some time, the learning percentage can be obtained from production records. The longer the production history, the more accurate the estimate will be. For new production projects, it is more a function of guesswork and expert opinion to estimate a learning curve percentage.

A firm's learning rate may differ from that of the industry due to differences in operating characteristics or even procedural differences. Often the rates will vary whether the industry rate is based on a single product or an entire product line. The manner in which the data were aggregated will cause rates to vary. Learning curves and organizational knowledge can depreciate if key individuals leave the organization or if technologies become inaccessible or difficult to use. Learning curves provide an excellent means to examine performance.

Learning curve theory was generalized into experience effect and it was made applicable to costs. The cumulative volume and average cost of production have an inverse relationship. As cumulative volume doubles average cost goes down by a certain percentage. For example, 90% learning curve implies, if the cumulative volume doubles, the average cost will come to 90% of the earlier average cost, This means, the firm selling more volume will be able to produce the incremental units at a lower cost, when the law is in operation and can sell at a lower price, thus enlarging the market demand for its products. Customers may shift their demand to that company and wait buying from it at lower price. Thus experience effect becomes a competitive strategy issue.

Scope and Definition of Manufacturing - Production Management



Manufacturing creates man-made goods from various materials. The goods, more specifically called finished  goods are created through manufacturing processes. Modern manufacturing employs machines to produce goods. Manufacturing management plans, organizes, acquires resources required for manufacture, allocates those resources to various departments, directs and controls manufacturing activity.The aims of manufacturing management are producing goods according to the specifications of the customer or of the product design department if it is made to stock product developed by the company, in amounts and by the schedule demanded at minimum cost. Manufacturing is carried out in factories or manufacturing plants. A manufacturing plant and the various activities carried out in it can also be described as a manufacturing system. Modern manufacturing systems have machines, methods, men, material, motive power, money and management essential components of the system. In terms of assets used in accounting terminology, we can say manufacturing system has both long term assets (fixed assets) and current assets (short term assets).

Manufacturing management involves plans and  decisions regarding long term assets and short term assets, manufacturing methods and manpower.

We can say the long term decisions are in the areas of design, installation and improvement of specified products, manufacturing processes to produce those products, equipment for production, transportation, inspection etc., industrial buildings, location of the plant, layout of the plant. recruitment of permanent manpower and training to develop them into skilled operators in the processes employed by the organization etc. Manufacturing management has to be effective and efficient. Effectiveness refers to producing what customers want in quantities according to the delivery time requested. Efficiency refers to the cost dimension and wastes that occur in manufacturing systems if special attention is not paid to eliminate them.  Industrial engineering is a specialized discipline providing efficiency improvement service at design, installation and improvement stages of manufacture.  

The short term decisions of manufacturing are related production quantities in year, quarter, month etc., inventories, temporary increases or reductions in manpower, overtime decisions to take care of sudden increases in demand, or some exigencies, short term cost budgets, and other incidental  day to day activities. Production planning and control, inventory planning and control, cost control, quality control, maintenance planning and control etc. are some of the well known short term manufacturing management areas that are well developed as independent subjects in manufacturing management degree curriculums. Similarly, new product development, process planning, facilities planning, manufacturing strategy, industrial engineering etc. are well developed subjects dealing with long term aspects of manufacturing management. Industrial engineering became a degree level curriculum as number of methods were developed in this area providing a scope for specially educated and trained professionals in this discipline. Value engineering, Methods Efficiency Engineering, Motion Study, Work Measurement, Ergonomics, Operations Research, Engineering Economics, Applied Statistics, Six Sigma, SMED, Poka Yoke Design etc. are full subjects in industrial engineering curriculums apart  from the basic engineering knowledge in various engineering branches, knowledge of business processes and managerial processes.

Manufacturing managers at various levels are responsible for both effectiveness and efficiency. But they can employ industrial engineers in their department either on full time basis or on assignment basis from their organization industrial engineering department or on consultancy basis from outside industrial engineering organizations.

Elwood S. Buffa, well known author of Modern Production Management first published in 1961 included the following topics to introduce the scope of production management. 

Long Term Decision Areas

Production processes
Automation and Use of Computers (Presently CAD-CAM or CIM)
Design of Jobs and Work Methods
Design of The Working Environment
Production Design of Products and Process Planning
Plant Location
Layout of Physical Facilities

Short Term Decision Areas

Inventory and Production Control
Maintenance
Control of Quality
Production Standards and Work Measurement
Wages and Labor Costs
Control and Improvement of Production Costs.


It is important to state that managerial skills are classified as business conceptual skills, people related skills and technical skills. So manufacturing managers need to have the knowledge to conceive a business opportunity to their department assets and people, knowledge to manage people related to the supply chain that starts  from suppliers of materials and ends with the customer, and technical skills in various methods involved in the manufacturing establishment to plan them, organized them, acquire resources, allocate resources, and direct and control the activities.

Principles of Directing

Related to the Purpose of Directing

Principle of harmony of objectives
    Effective directing depends on the extent to which individual objectives in cooperative activity are harmonized with group objectives.

Principles of Control


Related to the purpose of control

Principle of assurance of objective
    The task of control is to assure accomplishment of objectives by detecting potential or actual deviation from plans early enough to permit effective corrective action.

Principle of efficiency of controls
    The more control approaches and techniques detect and illuminate the causes of potential or actual deviations from plans with the minimum of costs or other unsought consequences, the more efficient these controls will be.

Principle of control responsibility
    The primary responsibility for the exercise of control rests in the manager charged with the execution of plans.

Principle of direct control
    The higher the quality of managers and their subordinates, the less will be the need for indirect controls.
(The principle may termed as principle of reduced controls. A superior can spend less time in control activities if he has more higher quality managers and their subordinates in his department.)


Structure of  Plans, Organization and Controls 


Principles Applicable to Structure of plans

Principle of planning premises
          If more people in an organization use common and consistent planning premises, the enterprise planning will be more coordinated.

Principle of policy framework
          If more policies, appropriate to the organization, are expressed in clear terms and form and if managers understand them, the plans of the enterprise will be more consistent.

Principle of timing
          If plans are structured to provide a network of derivatives plans in sequence, there will be more effectiveness in attainment of enterprise objectives.


Principles in Developing the Structure of Organization



The scalar Principle

          The more clear the line of authority from the ultimate authority for management in an enterprise (CEO)  to every subordinate position, the more effective will be decision making and organization communication at various levels in the organization.



Principle of delegation
          Authority is a tool for managing to contribute to enterprise objectives. Hence authority delegated to an individual manager should be adequate to assure his ability to accomplish results expected of him.


Principle of responsibility
          The responsibility of the subordinate to his superior for authority received by delegation is absolute, and no superior can escape responsibility for the activities of his subordinate to whom he in turn has delegated authority.

Principle of parity of authority and responsibility
The responsibility exacted for actions taken under authority delegated cannot be greater than that implied by the authority delegated, nor should it be less.

Principle of unity of command
          The more completely an individual has a reporting relationship to a single superior, the less the problem of conflict in instructions and the greater the feeling of personal responsibility.
         
The authority level Principle



          Maintenance of authority delegation requires that decisions within the authority competence of an individual manager be made by him and not be referred upward in the organization.

Principles related to Structure of control
Principle of reflection of plans
    The more controls are designed to deal with and reflect the specific nature and structure of plans, the more effective they will serve the interests of the enterprises and its managers.

Principle of organizational suitability
The more controls are designed to reflect the place in the organization structure where responsibility for action lies, the more they will facilitate correction of deviation of events from plans.

Principle of individuality of controls
    Controls have to be consistent with the position, operational responsibility, competence, and needs of the individuals who have to interpret the control measures and exercise control.



Process of Management Functions


Principles Applicable to Process of Planning

Principle of alternatives
          Select the plan which is the most effective and the most efficient to the attainment of a desired goal.

Principle of limiting factor
          Consider limiting factor in generating alternatives and selection from alternatives.

The commitment Principle
          Planning can cover a period over which commitment of resources can be clearly visualized.

The flexibility Principle
          Building flexibility in planning is beneficial, but cost of building flexibility needs to be evaluated against the benefits.

The Principle of navigational change
          Manager needs to periodically check events of the plan and redraw plans to maintain the move toward a desired goal.

Principle of competitive strategies
          In a competitive arena, it is important to choose plans in the light of what competitor will or will not do and navigate based on what competitors are doing or not doing.


Principles in the Process of organizing

Principle of balance
    the application of principles or techniques must be balanced in the light of the over-all effectiveness of the structure in meeting enterprise objectives.

Principle of flexibility
    The task of managers is to provide for attaining objectives in the face of changing environments. The more provisions are made for building organization flexibility, the more adequately organization structure can fulfill its purpose.

Principle of leadership facilitation
    The more an organization structure an authority delegations within it make possible for various managers to design and maintain an environment for performance, the more it will facilitate leadership abilities of managers.

The process of staffing


Principle of job definition


    Specifications for the job rest on organization requirements and on provision for incentives to induce effective and efficient performance of the tasks involved.



Principle of managerial appraisal


    Performance must be appraised against the management action required by superiors and against the standard of adherence in practice to managerial principles.

Principle of open competition in promotion
    Managers should be selected from among the best available candidates for the job, whether they are inside or outside the enterprise.

Principles  Applicable to Process of directing
Principle of unity of command
    The more completely an individual has a reporting relationship to a single superior, the less the problem of conflict in instructions and the greater the feeling of personal responsibility for results.

Principle of direct supervision
    Effective direction requires that management supplement objective methods of supervision with direct personal contact.

Principle of supervisory techniques
    Since people, tasks, and organizational environment vary, techniques of supervision will be most effective if appropriately varied.


Process of control

Principle of standards
    Effective control requires objective, accurate, and suitable controls.

Principle of critical-point control
    Effective control requires attention to those factors critical to appraising performance against an individual plan.

The exception Principle
    The more a manager concentrates his control on exceptions, the more efficient will be the results of this control.

Principle of flexibility of controls
    If controls are to remain effective despite failure or unforeseen changes in plans, flexibility is required in the design of controls.

Principle of action
Principle of Action
    Control is justified only if indicated or experienced deviations from plans are corrected through appropriate planning, organizing, staffing and directing.




Other heads

Principles  Related to the Cause of Organizing

Span of management Principle
          There is a limit at each managerial position on the number of persons an individual can effectively manage. But this number is not a fixed number and it will vary in accordance with underlying variables of the situation.

Principles in Departmentizing Activities

Principle of division of work


        The better an organization structure reflects a classification of the tasks and activities required for achievement of objectives and assists their coordination through creating a system of interrelated roles; and the more these roles are designed to fit the capabilities and motivations of people available to fill them, the more effective and efficient an organization structure will be.



Principle of functional definition


        The more a position or a department has clear definition of results expected, activities to be undertaken, organization authority delegated, and authority and informational relationships with other positions, the more adequately individual responsible can contribute toward accomplishing enterprise objectives.
