TL;DR
This study demonstrates the results of size estimation methods utilized on a large software intensive military application within the boundary of a project for Request for Proposal (RFP) preparation.
Abstract
Timing is one of the most critical factors of software size estimation. We need to know quite a bit about the software project to make a meaningful size estimate. However, most of the software estimates should be performed at the beginning of the life cycle, when we do not yet know the problem we are going to solve. In the literature, there are few early size estimation methods. This study demonstrates the results of size estimation methods utilized on a large software intensive military application within the boundary of a project for Request for Proposal (RFP) preparation.

Early and Extended Function Point: a new method for Function Points estimation
29 Citations1997Roberto Meli
The present paper describes a new technique to estimate Function Points (Early and Extended Function Points Method) and some experiences of its utilization and supports the thesis that it is necessary to exclude the General System Characteristics (GSC) from the capability to influence the final number of Function Points if the authors seek for a (almost) pure functional measure of the software size.
