Statistical Process Control (SPC) Tools: Pie Chart
Manufacturing Engineering
Lesson Plan
Performance Objectives
After completing this lesson, students will be able to discuss the purpose of a pie chart to the teacher’s
satisfaction.
Specific Objectives
 Explain the purpose of pie charts when used as a Statistical Process Control (SPC) tool
 Research and discuss terms used in Statistical Process Control
 Discuss how a pie chart can be used to illustrate project data efficiently
Terms
 Metrics- a visual representation of survey data, or the performance of a process or system,
usually through the use of charts and graphs
 Resources- assets like labor, money, and raw materials that are available to a company and used to
increase production or profit
 Real-time data- collecting data in an operational process while it happens
 Survey- a method of gathering data from specific groups of people by interviewing or through
questionnaires; the data is used to gain an understanding of group opinions, attitudes, and
preferences
 Pie Chart- a circular-shaped chart with individual, triangular sections; used to compare the parts of
data to the whole set
 Brainstorming- working with a group to create a list of possible options to correct a problem (or
defect)
 Variation- defects that occur during the work process
 Exploded Pie Chart- a circular-shaped chart with individual, triangular sections that are separated to
emphasize a specific section of data as compared to the whole data set
Time
This lesson should take approximately 180 minutes.

Introduction
The main purpose of this lesson is to help students understand the purpose of using a pie chart as an SPC tool.
Ask

If you were reviewing a page of data with five columns of numbers in numerical categories, how do you
make sense of it?

We will discuss the purpose of pie charts and how they are used to compare, consolidate, and help us
make sense of large amounts of data.
Say
Show
 Videos or photos of SPC tools and various styles of pie charts being used in presentations.

Application
Guided Practice
The teacher and students search the Internet to find different sources to gain more insight into the following
concepts:
 Unique ways pie charts are created and used in SPC in various manufacturing environments, and
 How companies use SPC to increase market share and increase efficiency.
Independent Practice
 Students write a 50-word essay on at least three projects they could use a pie chart with, to help them
complete the project more efficiently.
 Students research the different style formats of pie charts online that are used in the manufacturing
industry.
Summary
