Schedule Assessment Methods for Ballistic Missile Defense Ground-Based Software Development

Abstract

This report documents software development schedule models for ground-based segments of ballistic missile defense. The objective was to provide methods for assessing the reasonableness of proposed acquisition schedules for ground-based software of proposed system architectures. IDA developed time estimating relationships (TERs) using historical data from the Air Force Space and Missile Command (SMO) database. TERs are estimated using least-square regression analysis where the relevant duration in months is the dependent variable. Schedule drivers are the independent variables. Schedule drivers used include the rate at which resources are applied to the project specified as average staffing level as well as software size in source lines of code. This approach will help answer the question of how much program duration can be shortened with added staff while holding project size constant.
