Redefining Test Design to Reduce Defect- Slippage and Cost of Quality

Our client, one of the top 5 healthcare payers in the world was facing a production leakage problem and was looking to reduce costs by plugging the issue. With over 25 applications in the enterprise and more than 10000 cases running across every release, it was becoming difficult to achieve the desired results.

The client finally partnered with Virtusa for their innovation-driven, continuous optimization service offerings and looked to plug the defect leakage in production.

The Challenge

A labyrinthine QA schedule covering 10,000+ regression test cases, 5,000+ automated test cases and 15+ enterprise releases

  • Over 25 applications across the enterprise
  • Tight release schedule and frequently delayed code to QA
  • 10,000+ test cases to run every release
  • 5,000+ Automated test cases
  • 15+ Enterprise Releases
The Solution

Move away from a brute-force approach to an intelligent risk-based, prioritized set of optimal scenarios

  • Innovation driven, continuous optimization of our testing services
  • Optimal Scenario Calculation Algorithm (OSCAr) to optimize the client's testbeds, reducing the number of tests that are required to be executed to gain optimal test coverage
  • Visual requirement representation using mind maps
The Solution
The Benefit

100% QA coverage of requirements at 60-70% QA effort

  • A team was able to capture 30% of requirement related defects during the design phase (Shifting left the focus on quality, defect prevention vs. detection)
  • Overall Testing effort (Design and Execution) was reduced by ~30-40%
  • 100% testing coverage for business requirement
