Improving IT Application Services with Six Sigma
AgendaAgenda
Introduction Six Sigma process Synergy with IT Service Management Case Study Conclusion
IntroductionIntroduction
• Fastest growing business management system
• Developed by Motorola
• Popularized by GE
IntroductionIntroduction
• The process cannot produce more than 3.4 defects per million opportunities
• Two different processes in Six Sigma– DMADV- Define Measure Analyze Designs Verifies
the target processes; for new processes
– DMAIC- Define Measure Analyze Improve and Control the target process; for existing processes

• Maintain the gains made in the project
• Implement the knowledge in other parts of the organization
Synergy with IT Service ManagementSynergy with IT Service Management
Any IT driven organization is expected to have corporate IT good practices, which is the focus of Organization’s IT Service Management strategy
“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.”
As discussed, Six-Sigma- a management’s initiative for quality improvement and cost reduction.
Both focus on Quality and Cost Reduction.
Benefits of leveraging Six Sigma with ITSMBenefits of leveraging Six Sigma with ITSM
Provide better insight into the activities related to delivery and IT support services to the IT management
Providing consistent IT support for critical business functions with better service quality.
Benchmarking an accurate customer expectation level Improving the customer satisfaction experience for all the IT services
provided to them. Improved understanding of the existing and proposed IT service capability
and requirements. Better alignment of the personal effort linkage with the success of the
business and to the value of IT services. Increased implementation time to incorporate the changes for a better
success rate Usage of proven best practices to gain operational effectiveness in various
processes of the business.

Challenge: Improve IT service management practices internally
Solution:Combining Six Sigma and ITIL® to improve IT service management at GE
Business Value: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
Cost Savings:Saved $12 billion over five years and added $1 to earnings per share.
GoalsGoals
IT Consulting group at GE had the following goals:
Achieve ISO compliance Leverage ITIL® best practices Determine the current state of IT service Continually improve Establish ongoing measurements to ensure improvement/control
1 1 - DEFINE OPPORTUNITIES- DEFINE OPPORTUNITIESThe team produced 5 deliverables in the Define phase:
• Team Charter– describes the purpose, goals, and resources for the project
• Data Collection Plan– that includes such items as interview schedules and questions
• Critical to Quality (CTQ) outline– that identifies the critical success factors
• Current Situation Analysis– that was created using the CAT tool
• “as-is” Process Map Outline– that provides an understanding of the current processes to which the solution has to
be aligned
2 2 – MEASURE PERFORMANCE– MEASURE PERFORMANCE
The team produced 3 deliverables in the Measure phase:
• An accurate assessment– Of current process performance
• Detailed “as-is” process maps– Based on the outline created in phase-1
• Critical success factors (CTQ) summary chart– Based on the Critical To Quality outline
3 3 – ANALYZE FACTORS – ANALYZE FACTORS IMPACTING PERFORMANCEIMPACTING PERFORMANCE
The team produced 4 deliverables in the Analyze phase:
• Identified major process gaps– Created am “opportunities table” that provides solutions to map the
process gaps.
• Critical success factors (CTQ) benchmarked against IITL– To identify opportunities for improvement
• Created a Cause and Effect diagram– To demonstrate the effect of efficient process
• Pareto Chart for opportunities
4 4 – IMPROVE PERFORMANCE– IMPROVE PERFORMANCE
The team produced 3 deliverables in the Improve phase:
• “to-be” process maps– Were created based on innovative and cost effective ideas
• Prioritization– Of potential Solutions based on the ROI
• Improvement in the following:– Risk assessment– Failure Modes and Effect Analysis (FMEA)– Contingency Plan
• Creation of Solution Pilot
5 5 – CONTROL PERFORMANCE– CONTROL PERFORMANCE
The team produced 5 deliverables in the Control phase:
• Implemented full solution successfully• Defined Process metrics to control performance• Created a Multi Generational Project Plan• Implemented Control/Response plan (loop)• Completed Risk Mitigation actions
• Reduced Cost– by helping to minimize potential downtime and the adverse effects of system,
network, and application failures and install, move, add, change and decommission implementations.
• Enhanced decision making ability– by facilitating access to information throughout the organization, and by enabling
the enterprise wide use of outputs from an integrated framework of processes and tools through such devices as cross functional IT service dashboards.
• Improve IT Service levels– by creating operational efficiencies and enabling a linked IT Service Management
process loop for defining, measuring, analyzing, improving, and controlling service performance.
