Important Points from the Chapters


Ch. 1  The MIS Executive

The emergence of business and management information systems (MIS) in organizations has created an intense demand for well-trained, capable information systems managers to plan, organize, direct and control the powerful technology of computer-based information systems.

The topics presented in the book provide a managerial, organizational, behavioral, and technical treatment of MIS management.

MIS executives must blend management, business, technical, and interpersonal relations.

Ch. 2 The Organizational Use of Computers


Ch 4. Contingency Management and the MIS Function

The basic foundation of the contingency theory is that the effectiveness of a management approach is contingent upon the organizational environment in which it is applied. This abandons the concept that there is a "best way" to manage in all environments.

IS function is divided into three important functions: Systems development, production, technical services.

Ch 5. Achieving Job Productivity and Satisfaction

The most highly regarded of motivational theories are as follows:


  • Maslow's need hierarchy  -  A.G. Maslow 1943
  • Reinforcement  - B.F. Skinner  1953
  • Attribution theory - F. Heider 1958
  • Herzberg's dual factory theory - F. Herzberg 1959
  • Expectancy theory - V. Vroom 1964
  • Goal Setting - E.A. Locke 1976
Practical Guidelines

1. Efforts to increase motivation must first focus on the  employee's needs (Maslow, Herzberg)
2. work assignments and goals should be realistic and clearly defined;  rewards for performance should be practical and fulfill the  motivational needs of the employee (Locke, Vroom). 
3. Consequences or outcomes of good performance must approximate the expectations of the employee (Skinner, Heider)

Positive versus Negative Control of Behavior

Behavioral Management Tasks

Communicating
Imitation
Shaping
Reinforcement (Scheduling)

Ch. 6. Strategic Planning for MIS

A four stage model of MIS planning consisting of strategic planning, organization information requirements analysis, resource planning and allocation, and project planning is discussed in this chapter.

The challenges of MIS planning are:

1. Alignment of  the MIS plan with the overall strategies and objectives of the organization.
2. Design of  an information system structure or architecture for the organization.
3. Allocation of information  system development and operations resources among competing applications.
4. Completing information system projects on time and on schedule.

Relevant Information and Decision Making - Production Decisions - Review Notes

Many production decision models require accounting information.

Management accounting is branch of accounting wherein accountants provide data that helps in taking specific management decisions. Management has various subject based approaches and quantitative management decision making approach requires cost data for taking decisions using various optimization models. Revenue data is also required for management decision making. Decision making is future oriented and hence requires estimates of various costs and revenues for the future periods. But estimates of costs and revenues cannot be made and verified (for their accuracy) unless accounting system provides actual historical costs and revenues. Historical cost details provided by the accounting system can be modified for volume data and price expectations and estimates can be made more easily and accurately by operation personnel. Management cost objective related accounting work involves going through ledger data and summarizing the data that accurately reflects the cost elements that go into the cost objective in various transactions done by various departments of the organization.

Some of the decision models requiring cost data are:

1. Product mix determination: Requires revenue estimates and cost estimates to give profit estimates for each of the products considered for product mix determination.

2. Economic order quantity model (Purchase)

Simple economic order quantity formula is given by EOQ = SQRT (2AS/I)
where A = annual demand in units, S = order cost for each order issue and receipt and I = Inventory carrying cost per unit per annum.

To implement this model inventory control manager requires the estimates of ordering cost and inventory carrying cost.

3. Economic Order quantity model (Production)

The model is similar to purchase model. But now S is set up cost for the machine. To implement this model production planner or controller needs the estimate of set up cost for each machine. Management accountants have to take the set up cost for machine of each machine as cost objective and find out the set up cost.

4. Quality Cost

Quality cost model argues companies are incurring less cost in designing quality and preventing defects and are spending more in repairing defects and related losses. Management accountants have to take these cost ideas as cost objectives and prepare a statement showing cost of designing quality, cost of preventing defects and cost of actual defective parts. This data is going motivate the company management to increase investments in designing for quality and preventive devices or systems.

Relevant Information and Decision Making - HR and Other Functions

Accounting information is used in HR function decision making.

Human resource accounting is now a well developed field in management accounting.

Human resource management decision like investing in training are done through quantitative cost benefit models and accounting provides cost related inputs to these decision models in human resource management.

Cost Information for Transfer Pricing




The  "transfer price" is the amount charged by one segment of an organization for a product or service that it supplies to another segment of the same organization. The economic reason for charging transfer prices is
to be able to evaluate the performance of the group entities concerned. By charging prices for goods and services transferred within a group, managers of group entities are able to make the best possible decision as to whether to buy or sell goods and services inside or outside the group. About half of the major groups in the world transfer goods and services internally on the basis of a cost-oriented system. Some MNEs use only variable costs, other full costs, and still other use full costs plus a profit mark up (cost-plus method). Some use standard costs, other actual costs.


When  there is a competitive open market for the products or services transferred internally, an alternative method is to use the market price as a transfer price. The market price may be derived from published price lists for similar products and services (external market price) or it may be the price charged by a group entity to its external customers (internal market price). Sometimes, the transfer may take place  in an earlier stage of production instead of as marketable unit. In this case,  by subtracting costs and a reasonable profit of the last internal stage from market price, tansfer price can be determined.

Apart from the cost-based methods and transfer prices based on open market prices, a third way is negotiation among group entities  like independent parties. The transfer price resulting from such
negotiations is equally acceptable from a business economics point of view.

THE ARM'S LENGTH PRINCIPLE

Prices set for transactions between group entities should - for tax purposes - be derived from prices which would have been applied by unrelated parties in similar transactions under similar conditions in the open market.

This is the so-called "dealing at arm's length" principle, which is the international standard for transfer pricing matters.






PRACTICE AMONG MNEs

In 1992 the International Bureau of Fiscal Documentation sent a questionnaire on the use of transfer pricing methods to about 150 large MNEs in 20 countries.
Seventy answers from 12 countries provided useful information.
Main sectors of activity were: oil and chemicals, electronics, finance, forestry, metals, pharmaceuticals, retailing and textiles.

Per country the following pattern appears:
Belgium:
Germany:
large majority uses cost-plus/resale price,
goods and services: if CUP is available it is used, but nevertheless the majority applies cost-plus or
resale price;
intangibles: majority applies CUP.

CUP: Comparable Uncontrolled Price


Netherlands;
goods and services: almost all use cost plus or
resale price;
intangibles: great majority use cost-plus/resale
price, some CUP or mixed methods.

Sweden: majority applies CUP.
Switzerland:
large majority use cost-plus/resale price,

U.K. : goods: some CUP, other cost-plus/resale minus;
services: cost-plus;
intangibles: CUP.

U.S.A.:
goods and services: a clear majority applies costplus/resale

and other methods.
