Six Sigma

Six Sigma Skills Modules

This group of modules outlines the role Six Sigma will play in the manufacturing process. Each module in this competency group builds on the one before it, giving you confidence as you develop your knowledge in a way that is logical and intuitive.

Six Sigma and the Organization

Six Sigma and the Organization

This module explains how Six Sigma’s techniques and principles are employed to improve an organization’s bottom line by eliminating the variation in business processes that will result in defects (Estimated completion time: 1.9 hours).

Lean Principles

After completing this module, you will be able to describe how lean is used to eliminate waste using tools like 5S, kaizen, and poke-yoke; use a value stream map to identify waste; define value, value-added, and non-value-added; and explain the theory of constraints (Estimated completion time: 1.5 hours).

Design for Six-Sigma (DFSS)

This module describes how quality function deployment fits into the overall DFSS process, the purpose of QFD, the purpose of process and design failure mode and effects analyses (PFMEA and DFMEA), and how to create a QFD (Estimated completion time: 1 hour).

Six Sigma Define

Process Elements for Projects

This module defines the components of processes, process boundaries, process owners, and stakeholders. It also outlines the means of identifying customers and collecting customer data (Estimated completion time: 1.2 hours).

Project Management Basics

This module is designed to teach you how to create a project charter and perform risk analysis during the define phase of a Six Sigma project (Estimated completion time: 1.1 hours).

Management and Planning Tools

Upon completion of this module, you will be able to define an affinity diagram, interrelationship diagram, tree diagram, prioritization matrix, PDPC, and activity network diagram (Estimated completion time: 0.7 hours).

Business Results for Projects

After completing this module, you will be able to define Defects per Unit (DPU), Rolled Throughput Yield (RTY), and Defects per Million Opportunities (DPMO), as well as describe sigma level and process capability indices (Estimated completion time: 1.1 hours).

Team Dynamics and Performance

This module outlines the stages of team evolution, brainstorming, multivoting, nominal group technique, and the different roles of a Six Sigma team (Estimated completion time: 1.3 hours).

Define Phase Tools

This module is designed to acquaint you with common define phase tools, including audits, surveys, cause and effect diagrams, focus groups, check sheets, interviews, Gantt Charts, graphical charts, force field analysis, sampling plans, benchmarking, Advanced Quality Planning (AQP), and the Project Evaluation and Review Technique (PERT)/Critical Path Method (CPM) (Estimated completion time: 1.9 hours).

Six Sigma Measure

Process Analysis and Documentation

By completing this module, you will be able to identify process input variables, process output variables, process maps, written procedures, and work instructions. Additionally, you will be able to recognize the relationships between input variables and output variables (Estimated completion time: 1 hour).

Probability and Statistics

This modules outlines the process for using probability and statistics to measure samples of a product and provide mathematical proof of the quality of the product or process. Upon completion of this module, you will be able to distinguish between descriptive and inferential statistics and a population parameter and a sample statistic, as well as define a central limit theorem and its significance in statistics (Estimated completion time: 2.1 hours).

Collecting and Summarizing Data

This module shows you how to identify continuous or variable data and discrete or attribute data; construct and interpret diagrams; define nominal, ordinal, interval, and ratio measurement scales; and apply techniques such as random sampling, stratified sampling, and sample homogeneity (Estimated completion time: 1.7 hours).

Probability Distributions

After completing this module, you will be able to identify formulas for calculating the probability of data values of different probability distributions, and interpret normal, binomial, Poisson, t, chi square, and F distributions (Estimated completion time: 2.2 hours).

Measurement System Analysis

Upon completion of this module, you will be able to define measurement terms including sensitivity, accuracy, precision, bias, and linearity, as well as conduct gauge repeatability and reproducibility studies (Estimated completion time: 2.5 hours).

Process Capability Performance

This module is designed to teach you how to conduct a process capability study, distinguish between natural process limits and specification limits, calculate process and performance indices, and understand the differences between short-term and long-term capability (Estimated completion time: 1.9 hours).

Six Sigma Analyze

Exploratory Data Analysis

This module explains how to use statistical tools to perform an analysis of data to identify and confirm the variable that causes the most variation in a process or product. Upon completion, you will be able to create and interpret multi-vari studies and the linear correlation coefficient; identify the differences between positional, cyclical, and temporal variations; and determine the statistical significance of a linear correlation coefficient (Estimated completion time: 1.9 hours).

Hypotheses Test Basics

Upon completion of this module, you will be able to distinguish between statistical significance and practical significance; define null and alternative hypotheses, confidence levels, and confidence intervals; apply tests for significance level, power, and type I and type II errors; and calculate confidence intervals for population parameters (Estimated completion time: 1.5 hours).

Hypotheses Tests

This module outlines paired-comparison hypotheses tests, chi-square and its use to determine statistical significance, and one-way ANOVAs (Estimated completion time: 2.7 hours).
