Software engineering is becoming more procedural and controlled, but the estimation of IT projects is still regarded as a 'black art'. IT Project Estimation shows why it doesn't have to be. In this concise, easy-to-read guide, author Paul Coombs provides practical, detailed advice on IT project estimation. He shows why accurate estimates are needed, what different estimating methods can be used, and how to analyse the risks in order to make appropriate contingency allowances. He also covers pricing and billing strategies, and how experience of previous projects can be leveraged. Central to the book is a template for a cost model that incorporates task estimates, schedules, staff roles and costs, risk analysis, fixed costs, billing, and cashflow. Template Excel spreadsheets are included on the accompanying CD-ROM. Putting everything into practice, the end of the book is a complete case study, showing exactly how a simple example can be scaled up to a real-life problem. If you are an IT manager, project manager, or consultant, this book is for you.
