Change is difficult and it takes time. It is hard for people to change their own behavior, much less that of others. Change programs normally address attitudes, ideas, and rewards. But the behaviors of people in organizations are also strongly shaped by habits, routines, and social norms. Real change requires new power relationships, new work routines and new habits, not just intent.

You overcome the logical resistance to change by proving that a new approach actually works, usually on a small scale.

A good strategy focuses efforts on a target, and that focus can only be achieved by not diffusing energy in other directions - that is the meaning of Michael Porter's dictum of "choosing what not to do." At the same time, a good strategy chooses the right target to focus on, not wasting the focus of energy on a target that cannot be affected or that is unimportant - that is the meaning of Drucker's distinction between efficiency and effectiveness.

The US needs military/defense, economic, and social strategies. A medium-sized business, by contrast, is normally best off focusing its efforts on a single crucial objective.

The single most damaging misconception about strategy is that it is a set of financial performance goals. The so-called "strategies" created by many managements are nothing more than three-to-five year financial performance forecasts. They are then labeled "strategy" and shipped off to the board of directors which goes through the motions of discussing how big the numbers are. Strategy is not your aspirations. Strategy is concerned with how you will arrange your actions and resources to punch through the challenges you face.

As I worked to explain how to avoid bad strategy, I began to see that one cannot really evaluate or criticize a strategy unless there is a fairly clear statement of the problem the strategy is trying to solve.

A real strategy is a coherent mix of policy and action designed to overcome a significant challenge. So a sensible employee might indeed say that they have no idea what the organization's strategy is - because it seems to have none. Senior managers' so-called "strategies" are heavy with aspirations and goals, but light on how resources and strengths will be combined to achieve them.
