John P. Kotter's Leading Change: Why Transformation Efforts Fail is a classic of business literature, and an example of high-level analysis and evaluation.


In critical thinking, analysis is all about the sequence and features of arguments. When combined with evaluation of the strengths and weaknesses of an argument, it provides the perfect basis for understanding corporate strategies and direction. Kotter applied these skills to his own experiences of coaching large and small businesses through changes aimed at improving their performance.


At its heart, Kotter's conclusion was simple: unsuccessful transformations usually result from poor management decisions. His view was that it was not enough for executives to have management skills. Strong leadership is required, together with a clear process that can be used by all kinds of companies and organizations, no matter what sector they are operating in.


Looking at his own successes and failures alike, Kotter used his analytical skills to understand the sequence and features of relevant arguments before evaluating their strengths and distilling them down to identify common mistakes managers make when they try to implement change. This practical application of two core critical thinking skills allowed him to develop an eight-stage model for successful organizational transformation - a model still widely used twenty years on.
