    Study Notes

    Classifying the X's

    • The Cause & Effect Diagram is a tool to generate opinions about possible causes for defects
    • X's are classified into three categories:
      • Controllable (C) - related to knowledge
      • Procedural (P) - related to people and systems, a subset of controllable
      • Noise (N) - external or uncontrollable factors

    Chemical Purity Example

    • The example shows how to classify X's in a Cause & Effect Diagram
    • Categories used are:
      • Measurement
      • Manpower
      • Materials
      • Methods
      • Environment

    Cause and Effect Diagram

    • The diagram groups causes into six categories:
      • Measurement
      • People
      • Method
      • Materials
      • Equipment
      • Environment (also known as Mother Nature)

    Categories in the Cause and Effect Diagram

    • Measurement: related to measurement and measuring of a process activity or output
    • People: related to people, staffing, and organizations
    • Method: related to how the work is done, the way the process is actually conducted
    • Materials: related to parts, supplies, forms or information needed to execute a process
    • Equipment: related to tools used in the process
    • Environment: related to our work environment, market conditions and regulatory issues

    Introduction to the Course

    • The course focuses on process performance improvement using Six Sigma, Lean, and Process Management methodologies
    • The goal is to build knowledge and capability to improve process and business performance
