3 Todays Challenges Business lines rarely share information on tool research, usage, testing practices, and cost containment. Software Development Life Cycle models frequently compromise testing initiatives to meet deliverable deadlines. Performance Testing Practices vary in most projects. Knowledge Transfer – performance testing information leaves with consultants. Performance Tools are expensive, and very complex to integrate. No global approach to Performance Testing tools, techniques, or costs. Expensive consultants are frequently hired for Performance Testing Many projects cannot afford to make long term commitments to Performance testing. Decentralized approach to building and testing software. 2

4 Industry Trends Application owners often ask the following: Does my application scale to meet business goals? 75% of ERP systems fail to do so (Gartner) Does my application scale to meet business goals? 70% of performance problems can be resolved by configuration changes (survey of 3,000 HP/Mercury engagements) Can I resolve application bottlenecks? 40% of app bottlenecks are first noticed by a customer or executive (Mercury Survey) $2B + spent in app server overcapacity from 2001 to 2003 (Gartner) Have I overspent on infrastructure? 3

5 One Platform Solution T3 works to empower Business, Quality Assurance, and Development teams to deliver better software by centralizing all aspects of testing and performance management. Become Performance center of excellence Centralize performance testing and monitoring tools Global Performance testing execution capability Focus on quick cost savings wins! Reduce dependency on expensive consultancy QUICK START- Bring automation in quickly that addresses an immediate need. Reduce infrastructure support for testing Take a value approach and network it Forge alliances & partnerships Leverage vendor Purchasing Power Bringing the pieces together 4

6 Performance Approach Phase-driven approach to Performance Optimization Phase 1: Plan Fully Plan the project Organize the Team Determine the business goals Define the business process Inventory HW, SW and network Identify key participants Mobilize test team Create test plan Agree execution schedule Phase 2: Baseline Quantify the System Performance Create test cases Deploy monitoring agents Run initial test plan Document the baseline profile Compare baseline with target Phase 3: Optimize Iteratively Isolate and Reduce Bottlenecks Emulate production load Monitor system performance Identify problem areas Analyze root cause Determine resolution Apply modification Assess the Performance Improvements and Report Phase 4: Report Document improved throughput Increased capacity reduced error rate greater stability better user response time Compare with baseline and target Produce findings/recommendations Retain data for future comparison 5
