Problem Statement:• Classic push-pull between Time to Market pressures andQuality• Defects found in Stress testing are hard to debug, hard toreproduce, hard to root cause− Stress testing is a good method for finding a wide range of cornercase defects, but it is difficult to differentiate between corner caseand customer visible defects.− Internal development partners felt stress levels were unrealisticallyhigh. This caused them to discount stress defects.− Stress test groups and support wanted to ensure minimal defectescapes to customers.• What is “right” amount of Stress testing to meet customerneeds?• What are “right” defects to fix– i.e. defects customers willsee?March 2004 Copyright © 2004 HP corporate presentation.

Solutions:• Understand Customer found defects:− Analyze defects that escape to customers & feed testrecommendations back to appropriate place in testcontinuum.− Plug holes.Understand Customer Operational Profile (OP)and Increase Realism in Development & Test:Gather customer operational profile (OP: configurationand workload data).Compare customer OP’s to stress test configurationsand workloads.Educate testers, development partners and releasemanagement.March 2004 Copyright © 2004 HP corporate presentation.
