The first section of this manual contains a selective review of organizational change literature which focuses on predictive institutional variables as they affect the adoption-diffusion process. The second section describes the development of the Trouble Shooting Checklist (TSC). The third section presents two Trouble Shooting Checklists (TSC-A and TSC-B) and instructions for taking and scoring the tests. The TSC-A focuses on institutions which are concerned with adopting modules, and the TSC-B focuses on institutions which are concerned with adopting a psychological assessment battery with a counseling orientation. The fourth section describes the development of the scoring system and describes a summary of the score ranges for the checklists. The fifth section describes typical sequencing of events and action interventions for institutions which are either ideally, marginally, or unacceptably suited for the adoption of innovations. The final section of the manual offers guidelines for change agents faced with differing institutional situations. (Author)
