  1. Experience with Inspection in Ultralarge-Scale Developments Glen Russell IEEE Software Jan91 Text pp422-428

  2. Defects/KLOC • Caper Jones suggested what value? • Bell-Northern eliminated how many?

  3. Inspection Pace • Defects per person-hour • Figure 2 – inspection pace • Defect/KLOC vs LOC/hour

  4. Inspection vs Testing • Operational defects/proghour in testing vs inspection • Figure 3 p 425

  5. Why not pre-testing?

  6. Key Lessons in Achieving Widespread Inspection Use Robert Grady and Tom Van Slack IEEE Software July 94 Text pp 429-440

  7. Useful results in the articles? • What statistics were relevant? • ROI • What advice was good?

  8. Adoption Rates • Fig 1 pp430 • Four phases • Experimental • Initial guidelines • Widespread belief • Standardization

  9. Extent of Adoption Metric • Sidebar p438

  10. Estimated Savings • Sidebar p439

  11. Formal Inspections - WWW • NASA- satc.gsfc.nasa.gov • NASA Inspections - satc.gsfc.nasa.gov/Documents/fi/fipage.html • FTR page -www.ics.hawaii.edu/~johnson/FTR
