Solution: Virtualized services and created migrated to next gen payments system reusable test cases across multiple environments . Solution: Virtualized third-party systems . Results: Reduced testing time by 50%, otherwise unavailable for testing saving $800k over 3 years . Results: Reduced manual testing from 10 days to 10 minutes, saving over $7 million to date Major U.S. insurer Global manufacturer acquires Recognized manual efforts insufficient competitor for complex SOA and web services Migrate off rented infrastructure onto .Solution: Agile middleware solution created company’s standardized middleware platform to match the legacy systems’ functionality .Solution: Virtualized critical, unavailable systems .Results: Reduced testing by 95% to 2 hours; during migration reduced ‘rate filing’ validation by 94% to 320 .Results: Fully integrated in 6 months – 2 months hours ahead of schedule; saved significant rental costs and dependencies on third-party systems © 2016 IBM Corporation Page 13 13 Additional resources • Continuous Testing – An IBM point of view: http://www.ibm.com/developerworks/library/d-continuous-testing-shift- left-trs/index.html • IBM’s developerWorks Continuous Testing site: https://developer.ibm.com/testing/ • RTW Starter Editions (free version, no time/data limitation): https://developer.ibm.com/testing/docs/starter-editions/ © 2016 IBM Corporation Page 14 Questions Thank you! © 2016 IBM Corporation Page 15.
