This one-day, instructor-led workshop introduces the concepts of applied statistics, including statistical process control (SPC) and statistical quality control (SQC). Participants will learn how to identify, when to use, and how to interpret common statistical charts. No calculators are required!

Purpose
This workshop introduces basic statistical techniques used to make decisions about any type of process. It is designed to provide a foundation for participants who are implementing statistical process control and/or statistical quality control. The benefits of quantitative analysis tools, such as NWA Quality Analyst™, are highlighted.

Audience
This workshop is for New Users of Statistical Process Control Techniques.

Prerequisites
There are no prerequisites for this workshop other than an open mind and a willingness to participate. Note that this workshop, or a similar statistical background, is a prerequisite for the Quality Analyst New Users workshop.

Objectives

• Review the differences between SPC and SQC and discuss their benefits in the manufacturing environment.
• Discuss the history of SPC and its impact on process improvement.
• Introduce statistical terminology.
• Teach how attribute and variable data affect the application of statistics.
• Introduce common quantitative charts, when to use them, and how to interpret them.
• Teach the relationship between run charts and control charts, and histograms and process capability histograms.
• Demonstrate how SPC can be applied to any process, whether it’s the factory floor, the quality control laboratory, or the front office.
• Prepare the participant for training on SPC/SQC products such as QI Analyst and Quality Analyst.
• Prepare the participant for training on intermediate SPC topics.

Workshop Curriculum

Introduction
Introduce the differences between SPC and SQC and discuss their benefits in the manufacturing environment. Describe the philosophy and discuss the cultural implications of SPC.

History
Examine the history and background of SPC and it’s “inventor”, Dr. Walter A. Shewhart.

SPC Terminology
Describe the terminology used in SPC: variable data, attribute data, mean, median, mode, variation, accuracy, precision, and GR&R.

Basic Charts
Teach the use and interpretation of basic statistical charts: tally sheets, Pareto diagrams, run charts, and trend analysis.

Control Charts
Introduce and discuss the use of attribute and variable control charts: p, np, c, u, I-MR, and X-R.

Histograms and Process Capability
Explain histograms and process capability indices: Cp, Cpk. Review the voice of the process vs. voice of the customer. Examine normal distribution and skewness.

Correlations
Explore methods of determining the correlation between two sets of process data: correlation coefficient, scatter diagram, and linear regression.

Conclusion
Review the introductory topics of SPC. Discuss applied SPC/SQC using computer-based systems. Provide for open discussion, questions, and answers.
