ABSTRACT
As its name implies, this technique emphasizes change. To solve a problem, one must look for deviation from the norm. Change analysis follows a logical sequence. It is based on the principle of differences and considers problems to result from some unanticipated change. An analysis of the change is employed to determine causes using the following steps:
1. De€ne the problem. (What happened?) 2. Establish the norm. (What should have happened?) 3. Identify, locate, and describe the change. (What, where, when, to what extent?) 4. Specify what was and what was not affected. 5. Identify the distinctive features of the change. 6. List the possible causes. 7. Select the most likely causes.
