The Antecedents Behaviour Consequences model described in Managing Behavior on the Job, provides an easy to use framework for understanding behavior and performance on the job (and at home for that matter) and to shape behaviour/performance without the connotation of manipulating people. It prevents the error that most of us make at some time in our management career, of making assumptions about people's behavior, and helps focus instead on behaviour that you observe as the starting point for bringing about positive change.
Brown uses 'Tracking' sheets and other techniques to help focus on observed behavior, and describes how positive behaviour can occur by setting the right Antecedents and Consequences. Brown also describes the process of how negative behavior is encouraged, by providing positive reinforcement, and what to do to change this pattern, so that everyone performs better and the right things get rewarded.
No book is a panacea. This book doesn't wave a magic wand and make the process of managing people simple - although it does provide very helpful suggestions which work to make your job as a manager/project manager that much easier.
