Tips and Techniques for Statistics and Quality Improvement

Blog posts and articles about using Minitab software in quality improvement projects, research, and more.

Stability is a major issue in manufacturing. Parts need to be made to specifications to allow an easy assembly of final products. Unstable behaviors generate quality problems that customers must deal with later.

Yet there are often so many consecutive steps that a slight misalignment at one will impact the entire production line. Read on to see four challenges to stability, and how to address them.

Value stream mapping is a cornerstone of the Lean process improvement methodology, and also is a recognized tool used in Six Sigma. A value stream map illustrates the flow of materials and information as a product or service moves through a process. Creating a “current state” value stream map can help you identify waste and also makes it easier to envision an improved state for process in the future.

For a process improvement practitioner, finishing the Control Phase of the DMAIC process is your ticket to move on to your next project. You’ve done an excellent job leading the project team because they identified root causes, developed and implemented solutions to resolve those root causes, put a control plan in place and transitioned the process back to the Process Owner. Soon, however, you learn that the process...
