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.

This webinar evaluates any differences between replications of research studies that used ISBSG data, to estimate software-effort.
