Re-architecting test assets increases test coverage by 250%

10x reduction in post-release defects

30% defect leakage reduction from early stage

Terse requirement - Holes found & fixed at Stage#1

Test assessment accelerates integration

Smart automation - 3x reduction in time

Thank you - Have a great day!
