Chapter 1


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


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
