What is Six Sigma?• A goal of near perfection in meeting customer requirements• A sweeping culture change effort to position a company for

greater customer satisfaction, profitability and competitiveness• A comprehensive and flexible system for achieving, sustaining

and maximizing business success; uniquely driven by close understanding of customer needs, disciplined use of facts, data, and statistical analysis, and diligent attention to managing, improving and reinventing business processes

Is 99% Quality Good Enough?22,000 checks will be deducted from the

wrong bank accounts in the next 60 minutes.

20,000 incorrect drug prescriptions will be written in the next 12 months.

12 babies will be given to the wrong parents each day.

Six Sigma DMAIC Process

Measure

Analyze

Improve

Define: Define who your customers are, and what their requirements are for your products and services – Their expectations. Define your team goals, project boundaries, what you will focus on and what you won’t. Define the process you are striving to improve by mapping the process.

Define

Analyze

Improve

Measure: Eliminate guesswork and assumptions about what customers need and expect and how well processes are working. Collect data from many sources to determine speed in responding to customer requests, defect types and how frequently they occur, client feedback on how processes fit their needs, how clients rate us over time, etc. The data collection may suggest Charter revision.

Analyze: Grounded in the context of the customer and competitive environment, analyze is used to organize data and look for process problems and opportunities. This step helps to identify gaps between current and goal performance, prioritize opportunities to improve, identify sources of variation and root causes of problems in the process.

ImproveControl: Insure that the process improvements, once implemented, will “hold the gains” rather than revert to the same problems again. Various control tools such as statistical process control can be used. Other tools such as procedure documentation helps institutionalize the improvement.

Design

Design: Develop detailed design for new process. Determine and evaluate enabling elements. Create control and testing plan for new design. Use tools such as simulation, benchmarking, DOE, Quality Function Deployment (QFD), FMECA analysis, and cost/benefit analysis.

Design

Validate: Test detailed design with a pilot implementation. If successful, develop and execute a full-scale implementation. Tools in this step include: planning tools, flowcharts/other process management techniques, and work documentation.

Total Quality Management Quality system involving entire organization

from supplier to customer Objective: Meet or exceed customer needs

through company-wide continuous improvement

Early proponents W. Edwards Deming J. M. Juran Philip B. Crosby

Page 14: 2  six sigma

Continuous Improvement

Represents continual improvement of process & customer satisfaction

Involves all operations & work units

Page 15: 2  six sigma

Employee Empowerment Getting employees involved in product &

process improvements• 85% of quality problems are due to process &

material• Techniques• Talk to workers• Support workers Let workers make decisions Build teams & quality circles

Page 16: 2  six sigma

Quality Circles Group of 6-12 employees from same work

area Meet regularly to solve work-related

problems4 hours/month

Quality CostsCOST OF QUALITY IS THE COST OF

NON QUALITY

1: 10:100 Rule“A stitch in time saves nine”

Page 18: 2  six sigma

Types of Quality CostsThe cost of quality is generally classified into four categories

1. Cost of Prevention2. Cost of Appraisal3. Cost of Internal Failure4. Cost of External Failure

Page 19: 2  six sigma

Quality CostsCost of PreventionPrevention costs include those activities which remove and

prevent defects from occurring in the production process.Included are such activities as quality planning, production

reviews, training, and engineering analysis, which are incurred to ensure that poor quality is not produced. Appraisal

Those costs incurred to identify poor quality products after they occur but before shipment to customers. e.g. Inspection activity.

Page 20: 2  six sigma

Quality Costs

Internal FailureThose incurred during the production process.Include such items as machine downtime, poor quality

materials, scrap, and rework.External FailureThose incurred after the product is shipped.External failure costs include returns and allowances,

warranty costs, and hidden costs of customer dissatisfaction and lost market share.

Page 22: 2  six sigma

Conclusion Remember the earth revolves around the CUSTOMER.

Quality begets customers and customers beget quality. Let us all have action plans to support quality, this will make the world happy and earn us the blessing of God Almighty.
