There are many estimation models available in IT industry even some for software development or some specific to software testing. This paper is focusing on Bricked Estimation Method that’s scale the project/service or work package. As with any other estimating exercise, there is no "correct" answer. The sample solution presents Bricked Estimate Method based on one interpretation of the requirements and some reasonable estimating assumptions.
It is pre-requisite to have some understanding of (WBS) Work Breakdown Structure, (FPA) Functional Point Analysis and SDLC (Software Development Life Cycle) before implementing below method. Proposed method stands on WBS, FPA and use of weighting factors, this drives through first development estimation then sets testing estimation. Don’t worry; I have used small examples to explain my points. Proposed estimation drives through Development and testing estimation.
