Presentation Transcript

  1. COQUALMO Working Group Presentation Presenter: John D. Powell

  2. Participants • Moderator: Sunita Chulani-IBM • Scribes: John Powell-JPL & Keun Lee-USC • Floating Participant: Barry Boehm-USC • Participants • Michael Crowley-Motorola • Kimberly Dobson-Motorola • Jongmoon Baik-Motorola • Linda Brooks-TRW • Barbara Hirsh-Motorola • George Huling-LASPIN • Jung-Won Park-USC-CSE • John Serino-BAE Systems • Dick Stutzke-SAIC • Nancy Eickleman-Motorola

  3. Outline • Preliminary Presentation • Brainstorming Session • Identification of Research Issues • Prioritization of Research Topics

  4. Preliminary Presentations • Presentation for those who were unfamiliar with • COQUALMO • Orthogonal Defect Classification (ODC)

  5. The COQUALMO Model Baseline Defect Intro Rates/Ksloc Rqts 10 Rqts 20 Rqts 30 DI_DriverR,1 DI_DriverR,1 QAF = DMR COCOMO II Cost Drivers 10* DAFR 20* DAFD 30* DAFC Analysis Tools Rating DR_DriverR,1 DR_DriverR,2 DR_DriverR,3 Peer Reviews Rating Test Thoroughness and Tool Rating

  6. ODC • Defect Classification, Trigger activities • Signatures of defect rates • Comparison between projects and historical signatures • Take action based on these differences

  7. Brainstorm • ODC • Tailorable to different environments • Modeling for Spiral V. Waterfall Lifecycle • Modeling for Spiral life cycle is harder • Finding the Right Kind of Defect V Counting Defects • Implication for Risk Exposure Assessment

  8. Brainstorm (cont’) • Temporal information about defects may be needed • Account for timing of activities • Implication for cost • Granularity of COQUALMO Calibration • Allow for USC to Collect Data in the form affiliates collect it and make use of it.

  9. Brainstorming (cont’) • Can we compress 8-9 defect categories into 3-4 categories? • Build the capacity into the model to allow for changes in its classification scheme

  10. Identifying Issues/Research Topics • Full ODC Categorization • Cost/Benefit Analysis • Tailorability to waterfall, incremental model • Tailorability to Non-ODC Categories • Eliminating obstacles to data contribution • Reliability/MTBF – Product Model • Process Model

  11. Prioritizing Research Topics

  12. 1. Full ODC Categorization Importance Difficulty

  13. 2. Cost/Benefit Analysis Importance Difficulty

  14. 3. Tailorability to waterfall, incremental model Importance Difficulty

  15. 4. Tailorability to Non-ODC Categories Importance Difficulty

  16. 5. Eliminating obstacles to data contribution Importance Difficulty

  17. 6. Reliability/MTBF – Product Model Importance Difficulty

  18. 7. Process Model Importance Difficulty
