Enormous amounts of money are made and lost through activities related to Mergers, Acquisitions, Demergers, Buyouts and Alliances. It is a major management pre-occupation in many organisations in both the private and public sectors, in almost all parts of the world. Yet, there is a vast difference between those organisations who appear to manage these processes successfully and those who do not. As a result, there is a particularly critical role for more effective learning. This subject area has been extensively covered by "Long Range Planning" and this volume brings together a substantial selection of the key papers published by the Journal on the subject over the past 30 years. This is a volume of articles based on the research, case studies and practical experience of leading authorities that stand the test of time. It is a volume that should be read and digested by anyone concerned with any aspect of this particularly challenging area.
