Abstract:

The ability to quantify risk is essential to the processes of budgeting and scheduling. During the process of hiring to complete specified tasks, customers must be able to verify contractor estimates and to make sound judgements on the risks of cost overruns and time delays. The following two questions are central to this paper Do developers with little experience over- estimate or underestimate the complexity of the task because of their past experience, the assumption they make, the models they select, and how they define the model parameters What are the sources of risk associated with project cost estimation How can such risk be quantified To address these questions, this paper proposes a systematic acquisition process that is aimed at assessing and managing the risks of cost overruns and time delays associated with software development. The proposed acquisition process, which is composed of four phases listed below, is grounded on the following three basic premises a any single-value estimate of cost or completion time is inadequate to capture and represent the variability and uncertainty associated with cost and schedule. Acquisition process, Risk, Cost overrun.
