  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. NAVAL AVIATION SYSTEMS TEAM TEAM Goals / Objectives CSIP2003-456

  5. Established a Joint IV&V Cost Estimating (ICE) Team comprised of Personnel from NASA, the Naval Air Systems Command, Software Industry, and Software Engineering Academia • Developed & Delivered IV&V Effort Man-hour Tool (EMT - ProLogic) • Developed the Prototype IV&V Cost Estimating Tool (‘ICE Tool’) • Compiled & Distributed NASA Software IV&V Activity / Task Matrix, • corresponding Dictionary, and Standard ‘Mission Class’ Criteria Tables • Established Initial IV&V Cost Estimating Work Breakdown Structure • Developed & Delivered the Pre-Production ICE Tool • Demo during this 2003 NASA OSMA SAS • Production ICE Tool in-work; Hosting data tables on the NASA IV&V Tools Lab network server – Production Delivery in October 2003 NAVAL AVIATION SYSTEMS TEAM TEAM Major Accomplishments CSIP2003-456

  8. NAVAL AVIATION SYSTEMS TEAM TEAM IV&V Cost Estimating (ICE) Tool Walk-Through CSIP2003-456

  9. Continue to collect and refine IV&V Task Details (Man-hours, Scalars) and Mission Class criteria; Define & refine contract cost Reporting requirements to capture future IV&V costs • Survey Department of Defense programs for IV&V cost data to Assist in tuning / validating the NASA IV&V Cost Estimating Tools • Design and develop a statistical IV&V cost / forecast engine to Overlay the ICE Tool bottoms-up, engineering-based WBS cost estimate • Perform full-up Beta-testing of network-based ICE Tools; Analyze & Report findings; Develop “Tuning Utilities” and maintenance ‘Assistant’ • Initiate Independent testing of IV&V Cost Estimating Tools; Analyze Test results; Update / improve tools as required NAVAL AVIATION SYSTEMS TEAM TEAM Plans for Fiscal Year - 2004 … Transition!
