    5. 6. Building a TCoE Proof of concept Bring in Applabs rich experience, from Testing industry specific Best Practices Test tools and technology competency Access to the latest tools and technologies like automation tools, scripting languages, databases Knowledge management Integrated knowledge management system to help leverage our learning Reusable test suites & frameworks Proven & Structured Process Models. Design & implement best-of-breed solutions & technology Deepening of skills Through training & prototype development Measurement & Continuous Improvement Metrics to ensure enterprise wide implementation Regular check points to evaluate process maturity & Feedback Strategy definition Leverage on internal and external knowledge base to define objectives and scope of TCoE Assimilation Creating a knowledge base through Testing best practices Awareness Building a roadmap and vision for the Center of Excellence Deployment Using capabilities and components that the CoE generates, deploy across enterprise Improvement Improving value by repeated use – continuously refining the components Test Center of Excellence
    6. 7. TCoE – Assimilation Looking at every step of the Testing lifecycle Test Lifecycle Management Test Strategy Test Planning Test Case Design Test Execution Defect Report Analysis & Reports Test strategy document Test plan document Traceability matrix Test Scripts Defect reports Test summary reports R R R Analysis reports Test case document R Indicates review point Indicates testing process Indicates test artifacts Study Require- -ment Feedback Test Organization Test Environment Test Data Test Tools Test Metrics Release Management Review Process Software Development Lifecycle Configuration Management Change Management

    10. 11. TCoE - Improvement Process and Change Team Business Area 1 Define & improve Deployment Timelines Test consulting Transformation level Test execution Tactical level Execute & Feed back Testing Center of Excellence (TCOE) Business Area 2 Business Area 3 Business Area 4 Business Area n…… <ul><li>Improve project quality, reduce costs & delays </li></ul><ul><li>Measure improvement and establish benchmarks </li></ul><ul><li>Define a customized testing framework based on best practices </li></ul><ul><li>Educate people </li></ul><ul><li>Consistent logistics, automation and resources usage </li></ul>
    11. 12. Path to Success - Build a Business Case <ul><li>Define key objectives and scope </li></ul><ul><ul><li>What are my the key issues that the TCoE aims to solve </li></ul></ul><ul><ul><li>What are the priorities of these issues </li></ul></ul><ul><li>Engagement model with other departments and project teams </li></ul><ul><ul><li>To ensure its own success, the TCoE must set rules around how and when it will provide services to project teams. </li></ul></ul><ul><ul><li>Clearly defined entry and exit criteria for its operation </li></ul></ul><ul><li>Quantifiable benefits </li></ul><ul><ul><li>What is the ROI on this? </li></ul></ul><ul><ul><li>How do I select and measure success criteria </li></ul></ul><ul><li>Where will the funding come from? </li></ul><ul><ul><li>For many enterprises, TCoE usually remains a model without powers of enforcement because they do not have a mechanism to understand the ROI of implementing a COE strategy </li></ul></ul><ul><ul><li>Chargeback or direct from business budget </li></ul></ul>
    12. 13. Summary <ul><li>Fully understand what you are trying to achieve through the TCoE – don’t overestimate or oversell the solution </li></ul><ul><li>Plan accordingly by outlining a sensible and pragmatic roadmap to success – bite size chunks are the best approach </li></ul><ul><li>Position the TCoE as an evolutionary process – it’s about continual improvement, refinement and execution (not a one-off) </li></ul><ul><li>Define a well thought-out and structured business case – use metrics and evidence from process improvement initiatives to show the value of the TCoE </li></ul><ul><li>Ensure you have sponsorship at all levels – Business and IT </li></ul><ul><li>Questions to: [email_address] </li></ul>
