This paper describes a methodology for estimating IT projects. The span of knowledge required of an IT project estimator is much greater than just being able to characterize the software development. Having an understanding of the elements that comprise the organization infrastructure, deployment concepts, and security issues as well as the complex interactions within the environment are essential to preparing the estimate. The estimation methodology described here is composed of two parts: a formalized estimation structure, and a series of “catalogues” or mini-estimates that provide defaults to use as starting points for all critical estimation elements
