Improve Software Testing

Situation:

Application developers were spending too much time in Production fixing problems. Every hour spent fixing production issues was an hour not spent in the testing environment, costing the company an estimated $700K annually.

Task:

Optimize the test team’s process, reducing the need for developers to work in Production, build quality into the process, rather than fixing errors later.

Action Taken:

Led by Associate Green Belt, Dawn Noland, a Six Sigma project team was formed. Following the DMAIC phases of Define, Measure, Analyze, Improve, and Control, the team identified process improvements including:

  • System test results contained insufficient detail
  • Defects reporting and trending contained insufficient detail
  • Incongruities in test results reporting between groups

Improvements:

Using Six Sigma’s DMAIC process, the team made the following process improvements:

  1. Improved Root Cause Trend Reporting to detail the ticket error breakdown, recommending that the Development, Test, and Functional Analysis groups use the Root Cause Trend report to identify areas of improvement.
  2. Recommended Improvements to Root Cause Measurement Systems, including a limit the secondary root cause types to improve clarity in reporting.

Results:

Using Six Sigma’s DMAIC process, the team made the following process improvements:

  • Lowered Annual Cost Of Poor Quality (COPQ) by an Estimated $1.87M Annually. Reduced Developer hours in Production environment due to higher number of bugs detected early in Test cycle.
