It Makes Sense to Adjust

I believe this is a very strong article defining different approaches for corporate change and definitely worth looking at.

"It used to be that a business transformation was a once-in-a-lifetime event, the sort of fundamental reset prompted by a rare, short-lived disruption such as a new technology, a devastating scandal, or a dramatic shift in costs. But if the recent economic upheaval reveals anything, it is that companies of all sizes, in all industries, are operating in a more volatile, less predictable environment, and that change has become a way of life. To navigate such a rocky landscape, companies must be ready to repeatedly transform themselves — indeed, to institutionalize the capacity to alter strategies again and again — as business conditions require.
Each company’s strategy for approaching transformation falls into one of three categories. These categories in turn determine the level of transformation — the timing and the magnitude — that the company can support.
1. Reactive. This is the default transformation strategy; it is minimal, and has become second nature to most seasoned executives. A change in circumstances provokes a short-term response, generally an abrupt shift that requires little cross-company coordination or follow-up
2. Programmatic. This strategy is more comprehensive and is appropriate when major change is required and a company has sufficient lead time. In such circumstances, the company launches a widespread change initiative across the lines of business that are most affected
3. Sense-and-adjust. This is the most long-term and sustainable strategy, but only a few companies have successfully implemented it. Unlike the first two approaches, sense-and-adjust is dynamic, constantly and consistently smoothing out volatility in areas of business subject to swift and dramatic change, such as research and development or frontline operations like manufacturing and logistics."
