We only use experience, not data 2. We collect data, but just look at the numbers 3. We group the data so as to form charts and graphs 4. We use census data with descriptive statistics 5. We use sample data with descriptive statistics 6. We use sample data with inferential statistics Levels of Analysis: What level are you at? The Foundation of the Six Sigma Tools Goal ? Data is used to classify, describe, improve, control * Six Sigma Terms and Definitions 1. Customer any ‘One’ who receives a product, service or information from an operation or process. The term is frequently used to describe ‘External’ customers those who purchase the manufactured products or services which are the basis for the existence of the business. However, ‘Internal’ customers, also important, are internal GEL ‘persons’ who receive the intermediate or internal products or services from internal ‘Suppliers’. 2. CTQ Critical to Quality Characteristic a characteristic of a product, service or information which is important to the customer. CTQs must be measurable in either a ‘continuous scale’ manner (. , etc.) or descriptive manner (correct/incorrect, etc.) Six Sigma Terms and Definitions (cont’d) 3. Opportunity An event which generates an output (product, service or information). 4. Unit A discrete item (lamp, invoice, etc.) which possesses one or more CTQ (Note: ‘Units’ must be considered with regard with the specific CTQ(s) of concern by a customer and/or for a specific process) 5. Defect An output of an opportunity which does not meet a defined specification。 Continuous improvement 187。An Introduction to Six Sigma ZHongHong Liu ? To learn the systematic approach to Six Sigma problem solving M before A before I before C ? To understand some . tool kit ? To understand how you will be affected by Six Sigma methodology Training Objective ? Define Measure, Analyze, Improve and Control ? Define KPIV and KPOV ? Explain how process outputs are a function of the inputs ? Explain the value of measurement Training Objective Why Implement Six Sigma Now? “ Nothing New” Most of the tools have been around for decades Neglected due to difficulty and discipline BU
