© Copyright 2007 Fraunhofer Center MD 2 Fraunhofer Center for Empirical Software Engineering (College Park, MD) Not-for-profit, university-affiliated Mandate is applied research and technology transfer Via measurement, evaluation and improvement We bridge research and application, working with: –Government organizations (DoD, NASA, …) –Large industrial companies (Boeing, Motorola, …) –Small/medium-sized organizations (KeyMind,…) –National labs (Los Alamos Labs, ….) –Universities and research centers (CMU, USC, MIT, …) –…and others (SEI, MITRE, JHU/APL,...)

TTS = Development time + Computing time

© Copyright 2007 Fraunhofer Center MD 11 Using the Experience Base: The Best Practices Clearinghouse Flexible front- end I’m on a security-critical project in an industrial organization. Let me browse practices that help me reach CMMI KPAs. I’m working in the DoD and read about Fagan inspections. Is anyone at a similar organization using it? I’m working on an warfighter at an industry contractor organization. Show me practices that can help reduce schedule.
