Paul Coombs provides practical, detailed advice on IT project estimation for managers and consultants in this concise guide. Coombs demonstrates why accurate estimates are needed, the different estimating methods that can be used, and how to analyze risks in order to make appropriate contingency allowances. He also covers pricing and billing strategies, and how experience of previous projects can be leveraged. A vital component of 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 CDROM.
