This book is a practical 'how to' guide to using a set of models and tools which have been developed to help project managers and IT solution providers. It shows readers how to: understand the underlying reasons why change projects fail to deliver the expected benefits; identify the causes of actual or potential failure; quantify the key barriers to success, and take the appropriate action to overcome these. The approach, developed out of frustration at seeing so many modernisation and efficiency programmes failing to deliver the expected benefits, addresses the dual core of a change programme: processes and people. It has been researched and refined with the input of a wide range of experts in the field all of whom are excited about the insights the approach brings.
