Chapter 5. Cause-and-Effect Fishbone Diagram
What we will learn in this chapter is that it's critical to identify and examine all of the possible causes for a problem. This chapter explains how a cause-and-effect diagram is used.
The fishbone diagram is used primarily in the Define, Analyze, and Improve steps of the DMAIC process. It helps identify which input variables should be studied further and gives focus to the analysis.
The purpose of a fishbone diagram is to identify all the input variables that could be causing the problem of interest. Once we have a complete input variables list we identify the critical few key process input variables (KPIVs) to measure and further investigate.
