Montgomery, John Wiley & Sons, Inc.,  Certified Manager of Quality/Organizational Excellence”, 3 rd edition by Russell T. Westcott. ASQ Quality Press. Learning Objectives To introduce students to the use of statistical methods and other problem- solving techniques required in the area of quality control. The ability to control process performance using appropriate statistical tools. The ability to diagnose quality problems and develop sustainable improvement. To enable students to know how to measure the quality characteristics. In addition, to introduce students to apply the qulity improvement tools. In additional to road map to enterprise quality. Overview of quality management methodologies. Use of Six Sigma Fundamentals ( DMAIC)

Six Sigma 6 سيجما

بعض القياسات دائمة الاستخدام خلال تطبيق اسلوب 6 سيجما Sigma quality level= بعض العلاقات الرياضية الخاصة بأسلوب 6 سيجما : Number of operation steps=m Defects=D Unit=U Opportunities for a defect= O Yield=Y Total opportunities: TOP=U*O Defects per unit: DPU=D/U Defects per unit opportunity: DPO=DPU/O=D/(U*O) Defects per million opportunity: DPMO=DPO*

Process Capability قدره العمليات The Relationship between a Process and the Requirements of its Customer How Well Does the Process Meet Customer Needs?

l A Vision and Philosophical commitment to our consumers to offer the highest quality, lowest cost products l A Metric that demonstrates quality levels at % performance for products and processes l A Benchmark of our product and process capability for comparison to ‘best in class’ l A practical application of statistical Tools and Methods to help us measure, analyze, improve, and control our process What is Six Sigma

A Six Sigma process –A Six Sigma  process is one that has at least six standard deviations between the process mean and the nearest specification limit when centred. +/- 6 sigma % * Mean Value Lower Design SpecificationUpper Design Specification *Distribution shifted +/- 1.5  1.5 

Six Sigma The Concept

Deployment

Actions Required to Institutionalize a Quality Process –TOP DOWN COMMITMENT AND INVOLVEMENT Set the example, be active in the audit process –MEASUREMENT SYSTEM TO TRACK PROGRESS At both macro and micro levels –TOUGH GOAL SETTING (REACH OUT!!) Benchmark Best-In-Class -- audit often –PROVIDE THE REQUIRED EDUCATION The “Why” and “How To” –SPREAD THE SUCCESS STORIES

5s Key to work place improvement

Putting 5s to Work Who does not like a -Clean -Orderly -Disciplined Environment ? At home & At work !!! 5s AIMS at achieving this state

5-S Seiri - sort out Seiton -systematic arrangement Seiso - Scrub clean, Spic & Span Seiketsu – Standardize - State the rules Shitsuke - Self-discipline (Follow rules) KAIZEN  and GEMBAKAIZEN  are registered trade marks of KAIZEN INSTITUTE -JAPAN
