1 WHAT IS ESTIMATION What we mean by term Estimation? How do we measure software? Well, we measure software in terms of its SIZE which can be LOC, FP etc. Sizing is the prediction of product deliverables needed to fulfill the project requirements. Estimation is nothing but the prediction of effort (resource) needed to produce the deliverables. Estimation is not 100% accurate at the early stages of the SDLC and as we move ahead our estimation become more accurate. We will see this more into coming sections. Below is a BIG picture of Software Estimation: Scope Defined -> WBS Created (All dependencies and task identified and created) ->Estimate the Software Size->Estimate the Effort (Cost) and Duration-> Assign Resources->Schedule the Work. 1.1 ESTIMATION MODELS In below section we will see some widely used Estimation Techniques. In this article we will not go into much detail of each Estimation technique but will give you a high level detail of each technique.
