This book examines the flow of all information, relating not only to projects, but also to the more general information, that circulates in a contract. A model is presented, complete with definitions, that would help senior managers to analyze where there are deficiencies in existing management systems and provide the necessary basis for computerisation. The model will enable the benefits of information technology to be harnessed. This book will provide a benchmark against which contractors can identify their strengths and weaknesses in their flow of information. It applies equally to projects, sites and head offices.
