Practicing Organization Development (A guide for Consultants) - Part 18. Organization development (OD) is about planned change. As change has turned into the only constant, many managers and other people are pursuing change strategies with vigor. OD is a major strategy for leading and managing change at the individual, group, intergroup, organizational, interorganizational, and large systems levels.

We don t know for example whether contracting skills are any more or less important than implementation skills in successful OD practice. The time seems right therefore to apply a more quantitative approach to determine whether any structure exists within the list and to explore the relative importance of various competencies.

First the items were reviewed by the authors for use in a survey format. The items were screened for vocabulary jargon clarity assumptions and bias Emory 1980 Sudman Bradburn 1983 . In particular several items were double barreled and had to be split into two or more questions. For example one of the original items in the list was identify the formal and informal power in the client organization in order to gain further commitment and mobilize people in a common direction. This item was broken up into several items including identify formal power and confirm commitment of resources. On the other hand many items were considered redundant and eliminated. The final number of items used in this study was 141. Second the questionnaire
