Change Management Foundation Sample Exam

Why does a Six Sigma project with clean data and a signed-off control plan still drift back to the old way within a few months? Usually because nobody planned for the people who have to work the new process. Statistics settle what to change; psychology decides whether anyone changes. This guide covers resistance, how individuals adjust, stakeholder analysis, communication and keeping the gain.

Ask a Black Belt what makes a deployment hard and the answer is rarely the statistics. It is the conversation after the analysis, when a team that did not take part in the project is asked to work differently on Monday. Six Sigma is a low-engagement method by design: a small group of trained Black Belts and Green Belts does the measuring, while the people who live in the process every day mostly watch. That gap is where good projects lose their results.

The pages below treat the human side of a project as a skill in its own right, with methods you can apply at each DMAIC phase. They assume you already know the basics of Six Sigma and want to know why improvements stall and what to do about it. One section near the end covers a formal change management qualification for readers who want a structured vocabulary for this work.

Why do people resist a process change that the data says is better?

Resistance is rarely stubbornness. It is usually a sensible reaction to something the project team has not yet explained. Five causes account for most of what practitioners see, and each calls for a different response.
