Six Sigma

By the end of the program, participants will be able to answer the following questions:

Understand the background and meaning of the Six Sigma methodology and the role of the DMAIC process improvement cycle.
Identify the Voice of the Customer and translate it into Critical-to-Quality parameters.
Understand the concept of random variables, probability mass functions, and probability density functions.
Calculate probabilities using the Normal distribution.
Understand how the Central Limit Theorem applies to sampling and how to set up sampling plans.
Understand the importance of a Measurement System Analysis in a Six Sigma project.
Calculate Process Yield and Process Capability.
Perform a risk assessment using a Failure Modes and Effects Analysis.
Apply the Define and Measure phases of the DMAIC cycle in your work or research to identify problems and quantitatively assess the impact of process changes using statistical analysis.

Week 1: Six Sigma Introduction
Introduction to the Six Sigma Methodology and the DMAIC process improvement cycle. Understand the contributors to the cost of quality. Discuss the difference between defects and defectives in a process and how to calculate process yield, including comparing processes of different complexity using the metric DPMO.

Week 2: DEFINE – Defining the Problem
Discuss understanding customer expectations, using the Kano Model to categorize quality characteristics. Start a Six Sigma project’s first and most challenging task, Define the Problem, and review the critical content in a Project Charter.

Week 3: MEASURE – Statistics Review
Review of random variables and probability distributions used commonly in quality engineering, such as Binomial, Poisson, and Exponential. Cover descriptive statistics, emphasizing the importance of clearly communicating the results of your project.

Week 4: MEASURE – Normal Distribution
Learn the characteristics of the Normal Distribution and how to use the Standard Normal to calculate probabilities related to customarily distributed variables. Cover the Central Limit Theorem and how it relates to sampling theory.

Week 5: MEASURE – Process Mapping
We introduce Process Mapping, including SIPOC and Value Stream Mapping. We then identify the critical-to-quality characteristics of a Six Sigma project.

Week 6: MEASURE – Measurement System Analysis
Learn the basics of Measurement Theory and Sampling Plans, including
Precision, Accuracy, Linearity, Bias, Stability, Gage Repeatability & Reproducibility

Week 7: MEASURE – Process Capability
Introduction to Process Capability and the metrics CP/CPK for establishing our baseline process performance.

Week 8: Quality Topics and Course Summary
Cover the basics of Tolerance Design and the risk assessment tool Failure Mode and Effects Analysis (FMEA).
Review the complete Six Sigma Roadmap before summarizing and closing the course.
