'I was horrified by the grasshopper way in which I worked'...'The diary highlighted the amount of time I spent on work that should be done by subordinates.' These are two of the many comments of the managers who took part in the research described in this book, when 160 managers kept a specially designed diary for four weeks. The managers came from over a hundred industrial companies and from all the main functions. This new edition makes two major changes. First, it shows the relevance of this study in forty years of research into what managers do. It is still the largest study and the only one that shows how management training needs to take account both of what the 'average' manager does and of the great variation between different jobs and individuals. Second, it develops the last chapter now called 'Too Little Time? How to Help Yourself' by using the author's experience of helping many managers to apply the lessons given in the first edition. 'Too little time' is the complaint of many managers. This book is addressed to all those who do not positively enjoy having too little time. It can help managers to analyse what they do, why they do it, and whether they can do it better. '...an interesting and at the same time entertaining book.' Economic Journal
