IT-7 – Handout – In Pursuit of the One True Software Resource Data Reporting (SRDR) Database


Methods development for Space Vehicle (SV) cost estimating has mainly focused on acquisition cost, as acquisition makes up the majority of a SV’s lifecycle costs and has high interest from oversight agencies and congress. Tightening budgets and increased space vehicle life expectancy has bolstered the need to further refine methods for estimating SV maintenance costs.
This presentation walks through the development of Cost Estimating Relationships for Echelon 2 (E2) software maintenance for space systems. This work identifies potential E2 software maintenance cost drivers and strategies for collecting data that will accurately and consistently reveal the cost drivers. It discusses data collection challenges related to SW maintenance and ways to alleviate those challenges. This presentation demonstrates the process of identifying CER functional forms, evaluating the regression results, and selecting the best CER for estimating E2 software maintenance for space systems. The selected CER and results of the analysis are available for use by the community.
