  1. SRDR Data Analysis Workshop SummaryBrad ClarkRay MadachyThomas Tan 25th International Forum on COCOMO and Systems/Software Cost ModelingNovember 5, 2010

  2. Workshop Participants • Barry Boehm • Brad Clark • Sue Koolmanojwong • Gary Hafen • Peter In • Jo Ann Lane • Ilya Lipkin • Tom McGibbon • Ray Madachy • Arlene Minkiewicz • Ramin Moazeni • Vu Nguyen • Wilson Rosa • Bob Stoddard • Rick Selby • Tom Tan

  3. Agenda Data Reduction Building an Estimate Metrics Manual Application Domains

  4. Data Reduction • Level of data issues • Domain prioritization (top 7 identified) • Program reporting differences • Add manual appendix listing systems used in domain analysis • Manual should provide advice on system decomposition for estimation using the domain categories • Focus for users primarily in concept exploration and contract award (MS B or MS A if SLOC known)

  5. Normalizing Size • Reviewed SLOC definitions – no changes recommended • COTS estimation parameters differences • Reviewed backfilling assumptions for equivalent size – no changes • Model-based sizing issues • Different model types • Consider requirements-based sizing

  6. Reuse Parameters • SEER rework calculation parameters would need revision; many conflicts • Will not include in manual • SLOC conversion factors • Report as range • Modified size conversions • Fixes identified

  7. Effort Normalization • Backfilling approach reasonable with provided data • More interviews about missing data would help

  8. Multi Builds Evaluate approach in future about combining build data

  9. Team Experience Iterate on effort multipliers Provide guidelines on estimating TXP

  10. Distribution Percentages • Will provide domain-specific values for estimating effort allocation to phases

  11. Metrics Manual Outline • Add guidance on estimating integration effort • 3 approaches identified • Maintenance data available in Summer • Address non-counted labor hours

  12. Application Domains Survey taken on failure impacts Notes taken to crisp up domain definitions
