Optimizing IV&V in Mature Organizations Dan Mc. Caugherty, Frank Gmeindl, Pro. Logic, Inc. Christopher Fuhrman, ETS Technical Interchange and Initiative Review, NASA IV&V Facility 2003 -07 -29
Summary Slide • Objective • Related work • Research approach • Success Measures • Major Accomplishments to Date (1/2) • Open issues and concerns 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 2
Objective (1) • What optimization strategies can be taken by IV&V planners, knowing the appraised level of maturity of the development organization? 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 3
Objective (2) • What relationship exists (if any) between the level of effort spent on “managerial” IV&V activities and the assessed level of maturity of the development organization? 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 4
Objective (3) • Provide a set of guidelines to help IV&V planners tailor activities to a development organization’s mature processes 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 5

Research approach (1) • Analyze the CMMI Level 2 and 3 “typical work products” from IV&V perspective (FY 03) 1. Identify evaluation criteria for determining their usefulness to IV&V 2. Analyze the work products according to the criteria 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 8
1. Research approach (2) 1. Examine actual project planning data for one or more IV&V projects done with mature developers (FY 04) 1. See if or how the CMM/CMMI work products were used in the actual IV&V activities (prove useful relationship) 2. Calculate ratio of effort spent on “managerial” vs technical IV&V activities 2. Provide guidebook for IV&V planners (FY 04) 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 9
Success Measures • Reduced level of effort spent on non-technical IV&V activities • Ability to tailor IV&V activities in relationship to a developer’s mature processes based on an appraised maturity level • Ability to avoid unnecessarily redundant V&V activities between internal V&V and independent V&V 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 10

Major Accomplishments to Date (1/2) • Adaptation of research initiative for the CMMI rather than the CMM • Draft analysis of CMMI PAs and work products in the context of IEEE 1012 – Criteria for analysis of artifacts: • Useful for IV&V planning? • Useful/necessary in IV&V technical tasks? • Possibility of compromising technical independence? 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 12
Major Accomplishments to Date (2/2) • Two articles submitted to NASA Software Engineering Workshop (SEW) – Optimizing IV&V in Mature Organizations – Software V&V and the RUP 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 13

Open issues and concerns • Availability of IV&V project planning data for an IV&V project with a mature developer (i. e. , one that has been assessed/ appraised at a minimum of level 2 in CMM/CMMI) – Typical IV&V metrics are related to defects, etc. • Existence of appraised developers (yet to be identified) – GSFC in-house projects, e. g. , Global Precipitation Measurement, might “count” as a mature developer if they have had a CMM/CMMI appraisal 2003 -07 -29 Technical Interchange and Initiative Review, NASA IV&V Facility 15
