Modeling and Automating Software Assurance Cost Estimation

1. NAVAL AVIATION SYSTEMS TEAM TEAM NASA Office of Safety& Mission AssuranceIV&V Cost Estimation – A Joint NASA & US Navy Collaboration to Model & Automate the Process Software Assurance Symposium 30 July ~ 1 August 2003 Prepared by: Tom Robinson Research & Engineering Dept. Naval Air Depot Jacksonville, FL RobinsonTE@navair.navy.mil Software Assurance Research Program FY-2003

2. IV&V Cost Estimation – A Joint NASA & US Navy Collaboration • to Model and Automate the Process (CSIP2002-46) • The U.S. Navy has joined with National Aeronautics and Space Administration (NASA) in a collaborative effort to model and automate the process of cost estimation for Independent Verification & Validation (IV&V) of software. • The Naval Air Systems Command developed an easy-to-use cost tool for system software and hardware integration testing that uses a bottoms-up work breakdown structure (WBS), combined with statistical regression cost analysis, that yields cost estimates with a high degree of confidence. • The thrust of this Initiative is to develop similar tools for use by NASA on IV&V projects, and ultimately to improve the speed, accuracy, and consistency of NASA software IV&V cost estimating. NAVAL AVIATION SYSTEMS TEAM TEAM Initiative Description CSIP2003-456

3. Gather, Compile, and Analyze Data detailing Existing NASA Software IV&V Activities. • Establish / Validate a Benchmark with Processes and Procedures for Software IV&V in use by Industry, Academia, and other Government Agencies. • Refine NASA Software IV&V Program Management Processes, Interfaces and Tools necessary to Improve the Speed and Accuracy of Software IV&V Program Scheduling, Risk Assessment, and Cost Estimating. • Develop, prototype, and validate new NASA Software IV&V Program Cost Estimating Tools. • Improve and Evolve NASA Software IV&V Business Processes and Techniques.
