2. A lack of effective software delivery impacts the entire business CHALLENGES CHALLENGES Costly, error prone manual processes and efforts to deliver software across an enterprise Slow deployment to development and test environments leave teams waiting and unproductive Upgrade risk due to managing multiple application configurations and versions across servers BusinessOwners Development/Test Operations/Production Customers Software glitch costs major trading firm $440 million in 45 minutes Major telecom provider paid out $2.7 million to 47,000 customers overchargedafter a software glitch A bad software upgrade at a global bank leftmillionsunable to access money for four days 2

DevOps: A blueprint for continuous delivery of software innovation dev·ops noun \'dev-äps\ Enterprise capability for continuous software delivery that enables clients to seize market opportunities and reduce time to customer feedback. DevOps Lifecycle in Action Business Owners/Product Management Development/Test/Delivery Operations/Manufacturing/Support Customers • Accelerated software delivery • Reduced time to obtain and respond to customer feedback • Improved governance across the lifecycle • Balanced quality, cost and speed Continuous innovation, Feedback and Improvements 6

8. Cost is a significant driver During the CODING phase $80/defect 80% of development costs are spent identifying and correcting defects!* Once releasedas a product $7,600/defect + Law suits, loss of customer trust, damage to brand During the QA/TESTING phase $960/defect During the BUILD phase $240/defect *National Institute of Standards & Technology Source: GBS Industry standard study Defect cost derived in assuming it takes 8 hrs to find, fix and repair a defect when found in code and unit test. Defect FFR cost for other phases calculated by using the multiplier on a blended rate of $80/hr. 8

9. Testing and Delivery – where are customers today? Java / .Net teams PromoteResults Install & Configure Run ManualTests Compile AutomatedUnit Test Run AutomatedTests Weeks to Months Hours to days Mainframe teams current state ** PromoteResults Promote & Configure Run ManualTests Compile ** Feedback from mainframe customers

10. Stage One – Increase availability of z/OS testing environment and resources Reusable integration tests simplify testing across layers Automated, continuous testing with isolated development and test environment Development Environment Change Request Promote To QA Frequent, rapid feedback earlier to improve quality Higher quality going into QA Developer Rapid Feedback • Lower cost of application testing using off-mainframe z/OS test environment • Fast, dependable, automatic feedback speeds time to market • Enables confidence by automatically tracking and promoting code health
