Effort Estimation
There are two fundamental approaches to support software project’s effort and cost estimation: parametric cost models and analogy-based processes. The Work Breakdown Structure (WBS) is a planning tool, often poorly used to support such crucial needs. We must clearly identify, in the WBS, the activities covered by the parametric models and those should be estimated as a result of the expert judgement. The presentation will focus on analyzing these aspects by presenting good and bad practices in the use of these support techniques.
