Analysis of Schedule Determination in Software Program Development and Software Development Estimation Models

Abstract

Accurate schedule estimation in software development programs is important because delays in the schedule of a software development program can cause delays in the entire schedule of a weapon system. In order to more accurately predict the schedule of a software development program, estimators need to know which development factors affect schedule. This thesis reports twelve factors identified as heavily influencing software development experts and from interviews with DOD Program Managers/Engineers and commercial experts who have had experience with software development programs. Also, there are many commercial software development estimation models on the market today. Five of these models were analyzed for their accuracy in predicting software development programs. The models analyzed were COCOMO, PRICE-S, SOFTCOST-R, SPOR/20, and SYSTEM-3. Inputs to these models were also analyzed for their correlation to schedule prediction.
