This is another in the "in Ninety Minutes" series, which offers the reader a comprehensive but easily read and easily digestible text, covering a specific topic in an hour and a half of study. It is still the case in many organisations that managers are selected primarily for their knowledge of the main productive process in which the business is involved. Whatever else is required in the appointment is often overlooked - this results in good technical people having to face a raft of new responsibil-ities of which they have little or no knowledge. This excellent book is also a self-managed personal development programme which encourages people to become adept in the process of Active Learning - learning-by-doing, the same principles used when learning to ride a bicycle or drive a car. By working through a series of four Active Learning modules, the reader will learn to become a better manager and use techniques immediately within the operational requirements of the job. The great joy of this method is that huge improvements are possible while not losing working time with off-the-job training.
