Leader has to innovate and increase productivity.
Leaders have to be effective and efficient
Leaders have to improve top line (revenues) and bottom line (profits). To increase profits they have to reduce costs relatively. Unit costs have to come down.
Leader has to come up with new ideas to improve the product, or design a new product. He has to find new markets. This is a top line activity.
Leader has to increase productivity. Leader must help his followers to produce more, more of an improved product. This will reduce cost and increase contribution. Increase in contribution helps in providing more income to followers. Productivity provides mental satisfaction first due to achievement, second due to the appreciation provided by leaders to follower. And then the extra income completes the feedback loop. If you have done some very good, you deserve a reward from the external environment.
Innovation distinguishes between a leader and a follower. - Steve Jobs
