Abstract

Executive Summary Most commonly available software cost estimation methodologies and tools use either source lines of code (SLOC) or function point (FP) measures as the basis for the estimate. While these methodologies and tools may suffice for software projects that use structured software development techniques, when object-oriented (OO) techniques such as use-case modeling are employed, it is more effective to use a methodology that takes advantage of the information provided by the use cases, scenarios, and more in-depth object-oriented metrics. Furthermore, as an organization becomes proficient in developing object-oriented system software, the traditional metrics of SLOC and FPs become less useful because each individual line of code becomes less likely to be like the others. Using use cases as the basis for effort estimation is a valuable addition to the tools available to a project manager, particularly for those projects where use cases are produced as part of the life-cycle process. Though use c...
