  2. ”Beware of bugs in the above code;I have only proved it correct, not tried it.” Donald E. Knuth ”If anything can go wrong, it will.” Edward A. Murphy

  3. Topics • Motivation • Introduction • Agile Processes / PairProgramming • Techniques • Evaluation • Hypotheses • Pilot Study • Results • Agile Inspection and Implementation Process • Follow-Up

  4. Agile Processes

  5. Techniques with priorized Use-Cases • Usage-based Reading, UBR (Biffl et al., Thelin et al., Winkler et al.) • reading through artifacts • Usage-based Testing, UBT-i bzw. TDI • replicated version of UBT (Andersson et al.) • finding matching equivalence class • create test-cases for inspection • Usage-based Implementing, UBI • PairProgramming (Williams et al., Cockburn et al.) • detecting faults while implementing
