  1. 1. Magesh Mani Sohel Imroz Udaya Vangipurapu 4/27/2005 Improving IT Application Services with Six Sigma
  2. 2. Agenda <ul><li>Introduction </li></ul><ul><li>Six Sigma process </li></ul><ul><li>Synergy with IT Service Management </li></ul><ul><li>Case Study </li></ul><ul><li>Conclusion </li></ul>
  3. 3. Introduction <ul><li>Fastest growing business management system </li></ul><ul><li>Developed by Motorola </li></ul><ul><li>Popularized by GE </li></ul>
  4. 4. Introduction <ul><li>The process cannot produce more than 3.4 defects per million opportunities </li></ul><ul><li>Two different processes in Six Sigma </li></ul><ul><ul><li>DMADV - D efine M easure A nalyze D esigns V erifies the target processes; for new processes </li></ul></ul><ul><ul><li>DMAIC- D efine M easure A nalyze I mprove and C ontrol the target process; for existing processes </li></ul></ul>
  5. 5. Six Sigma process
  6. 6. Define Phase <ul><li>Core processes </li></ul><ul><li>Scope of the project </li></ul><ul><li>Requirements </li></ul><ul><li>Resources </li></ul><ul><li>Organizational support </li></ul><ul><li>Tools: Project Charter, Process Flowchart </li></ul>

Improve Phase <ul><li>Ideas and solution put to work </li></ul><ul><li>Find the best solution </li></ul><ul><li>Experiment and trials </li></ul><ul><li>Develop standards and procedures </li></ul><ul><li>Finalize documentation </li></ul><ul><li>Celebrate!! </li></ul><ul><li>Tools: Control Chart, Cost Savings calculation </li></ul>
  10. 10. Control Phase <ul><li>Performance tracking mechanisms and measurements </li></ul><ul><li>Maintain the gains made in the project </li></ul><ul><li>Implement the knowledge in other parts of the organization </li></ul>
  11. 11. Synergy with IT Service Management <ul><li>Any IT driven organization is expected to have corporate IT good practices, which is the focus of Organization’s IT Service Management strategy </li></ul><ul><li>“ ITSM is a method to manage IT Service Provisioning across the enterprise and through a full cycle of Service Delivery and Service Support. By nature it uses best practices to manage the balance between Quality of Service and Cost of Service, with a focus on the profitability of the IT customers.” </li></ul><ul><li>As discussed, Six-Sigma- a management’s initiative for quality improvement and cost reduction. </li></ul><ul><li>Both focus on Quality and Cost Reduction . </li></ul>
  12. 12. Benefits of leveraging Six Sigma with ITSM <ul><li>Provide better insight into the activities related to delivery and IT support services to the IT management </li></ul><ul><li>Providing consistent IT support for critical business functions with better service quality. </li></ul><ul><li>Benchmarking an accurate customer expectation level </li></ul><ul><li>Improving the customer satisfaction experience for all the IT services provided to them. </li></ul><ul><li>Improved understanding of the existing and proposed IT service capability and requirements. </li></ul><ul><li>Better alignment of the personal effort linkage with the success of the business and to the value of IT services. </li></ul><ul><li>Increased implementation time to incorporate the changes for a better success rate </li></ul><ul><li>Usage of proven best practices to gain operational effectiveness in various processes of the business. </li></ul>
  13. 14. Case Study - 1 <ul><li>Challenge: </li></ul><ul><li>Improve IT service management practices internally </li></ul><ul><li>Solution: </li></ul><ul><li>Combining Six Sigma and ITIL® to improve IT service management at GE </li></ul><ul><li>Business Value: </li></ul><ul><li>Reduced Cost, Enhanced decision making ability, Improve IT service levels by creating operational efficiencies enabling a linked IT Service Management process loop for defining, measuring, analyzing, improving, and controlling service performance </li></ul><ul><li>Cost Savings: </li></ul><ul><li>Saved $12 billion over five years and added $1 to earnings per share. </li></ul>
  14. 15. Goals <ul><li>IT Consulting group at GE had the following goals: </li></ul><ul><li>Achieve ISO compliance </li></ul><ul><li>Leverage ITIL® best practices </li></ul><ul><li>Determine the current state of IT service </li></ul><ul><li>Continually improve </li></ul><ul><li>Establish ongoing measurements to ensure improvement/control </li></ul>
  15. 16. 1 - DEFINE OPPORTUNITIES <ul><li>The team produced 5 deliverables in the Define phase: </li></ul><ul><li>Team Charter </li></ul><ul><ul><li>describes the purpose, goals, and resources for the project </li></ul></ul><ul><li>Data Collection Plan </li></ul><ul><ul><li>that includes such items as interview schedules and questions </li></ul></ul><ul><li>Critical to Quality (CTQ) outline </li></ul><ul><ul><li>that identifies the critical success factors </li></ul></ul><ul><li>Current Situation Analysis </li></ul><ul><ul><li>that was created using the CAT tool </li></ul></ul><ul><li>“ as-is” Process Map Outline </li></ul><ul><ul><li>that provides an understanding of the current processes to which the solution has to be aligned </li></ul></ul>
  16. 17. 2 – MEASURE PERFORMANCE <ul><li>The team produced 3 deliverables in the Measure phase: </li></ul><ul><li>An accurate assessment </li></ul><ul><ul><li>Of current process performance </li></ul></ul><ul><li>Detailed “as-is” process maps </li></ul><ul><ul><li>Based on the outline created in phase-1 </li></ul></ul><ul><li>Critical success factors (CTQ) summary chart </li></ul><ul><ul><li>Based on the Critical To Quality outline </li></ul></ul>
