Estimating the gathering of requirements is hard. Not as hard as scheduling innovation, but easier than estimating implementation effort. One step in gathering requirements is often the documentation of the “as-is” process – how things exist today. We provide a framework for building those estimates – making the job a little bit easier.
Foundation Series: Basic PERT Estimate Tutorial
PERT is a technique for providing definitive estimates of how long it will take to complete tasks. We often estimate, or scope, the amount of time it will take us to complete a task or tasks. PERT allows us to provide not only an estimate, but a measure of how good the estimate is. Good estimates are a critical element in any software planning strategy. In this post, we will present an introduction to using PERT, explain how it works and how to interpret PERT estimates.
