For busy managers and management students this book provides a guide through the apparent maze of theories on behaviour, The manager's role is to direct human behaviour at work, and to produce results he must be able to interpret the attitudes and behaviour of his employees, peers and superiors. The book therefore consists of a series of Incidents illustrating individual, group and inter-group behaviour in a working environ- ment as seen through the eyes of a busy manager, and is designed to help the reader to test and enlarge upon his knowledge and to develop his social skills. Each Incident is accompanied by a short summary of the relevant theories of behaviour and a questionnaire which gives the reader an opportunity to analyse himself as an initial requirement before he can interpret behaviour. In Parts II and III the questionnaires help the reader also to exercise his . skills in observation and, increasingly, to apply what he has learned. This method, involving self-analysis, knowledge, observation and practice, is the result of a well-tested and -tried programme at the Portsmouth Management Center and will be an invaluable aid to all who are concerned with the day-to-day management of behaviour at work.
