Validation and Verification using Rational DOORS for Aerospace

  1. 1. Validation and Verification using Rational DOORS for Aerospace Costas Aravidis, 9 October 2013
  2. 2. Agenda • Before and After • Process And Tools • Application • Extra 9 October 2013 V&V Concept and Design 2
  3. 3. Chapter 1 • Before and After • Process And Tools • Application • Extra 9 October 2013 Before and After V&V Concept and Design 3
  4. 4. Before • We did not have a process • We did not have standards • We did not have control over the scripts • We did not have control over the documents • We did not have an overview of testing • We did not have an overview of changes • We did not know what to test, how and why • We could not measure progress 9 October 2013 V&V Concept and Design 4
  5. 5. After • Identify and analyse the changes (regression) • Provide traceability and coverage of testing • Standardise procedure, script and results • Report pass/failed for each requirement • Measure progress in every stage to distribute work efficiently • Have a process that complies with ARP 4754, DO-178B and DO-254 • Produce Documentation • Increase productivity 9 October 2013 V&V Concept and Design 5
