Abstract

In this case study, students assume the role of a quality assurance team that is in charge of determining potential causes and solutions for potato chip bags that open during the shipping process. Students will use basic quality control tools to evaluate the process, brainstorm potential causes, determine the most likely cause of the problem, and develop potential solutions for the problem. A couple of the case exercises require students to create fishbone (Ishikawa) diagrams. A summative writing assignment and a set of optional questions for further exploration are included. This case study is appropriate for courses focusing on quality management in industrial settings, as well as a general undergraduate statistics or experimental design course.


Objectives

  • Apply basic quality tools (e.g., process flow diagrams, fishbone diagrams) to a given food process.
  • Compare different potential causes for a process problem and select the most likely cause given information about the process.
  • Develop potential solutions for a process problem.
  • Explain how to use basic quality tools to determine the effectiveness of potential solutions to a processing issue.
