Contracting for Project Management [PDF ebook] 

In all but the smallest of projects the project sponsor inevitably has to buy in the goods and services of other suppliers. This requires people to make contracts so that they know the basis on which they are working with each other and to deal with any disagreements that subsequently arise. So a knowledge of contracting specifically for project management is essential if a project is to avoid difficulties and reach a successful conclusion. This book concentrates specifically on the contracting issues that surround projects of any size.
