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

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
