Use the method that helps answer the question.

A workaround may be protecting the customer or keeping work moving. Keep that protection until a tested replacement is ready. Ask: What fails without the workaround? Who repeats it, how often, and why? What is the cost or delay? Who owns fixing the cause? Separate immediate containment from a lasting correction. Follow a recent example, test the replacement with exceptions, then retire the old step only when the owner accepts the result.

A review does not have to wait for a complaint. Walk through the normal process and its exceptions: missing information, staff absence, unusual volume, a system failure, and a handoff between teams. Ask what could go wrong, who would be affected, what prevents it, and how quickly someone would notice. Agree on the most important checks and who responds. The aim is to reduce surprises, not promise to find every issue. Some risks require the relevant technical or professional specialist.

DMAIC organizes improvement of an existing process: define the problem and intended result; establish trustworthy starting measures; investigate causes; test and implement a change; then maintain the result with an owner and checks. Use the discipline to answer the next useful question. A method name does not replace evidence, technical expertise, or team involvement. It can complement Wolfers Way’s Discover, Diagnose, Design, Deliver approach.

Plan a limited change and what you expect to observe. Try it within an agreed scope. Compare the result with the starting point, including quality and service. Then adopt, adjust, or stop based on what you learned. Define an owner, success checks, and a way back before testing. Do not roll out broadly just because one attempt appeared faster.

For each important step, list how it could fail, the effect, likely causes, existing prevention, and how it would be detected. Use the team’s knowledge and available evidence to prioritize action. Pay attention to serious consequences even if they are uncommon. Assign an owner, due date, and verification for each selected action. A simple review is a starting point, not a certified or complete risk assessment.

Look for a way to prevent the error at its source or make it immediately visible: a clear required field, distinct locations, a verified identifier, or a designed sequence. Choose the control for the actual failure. Test normal work and exceptions. A control that people must bypass to finish the job needs investigation. Do not remove an existing check until the replacement is validated.

Group observed incidents by a consistent cause or category, then compare their frequency or cost over the same period. Focus investigation where the evidence shows the largest burden. Do not assume the split will be exactly 80/20. Review serious low-frequency risks separately so a count ranking does not hide them.

Agree who owns the process, what measure or check matters, how often it is reviewed, and what happens when it is outside the agreed expectation. Keep the procedure, training, backup coverage, and exception path usable. Review the process after implementation and after material changes. A dashboard without someone responsible for acting is not a complete control plan.

Belt names describe levels of training or responsibility in Six Sigma programs; exact requirements depend on the provider. ASQ describes Green Belts as supporting quality-improvement work and Black Belts as having deeper DMAIC leadership knowledge. Wolf can explain selected methods, but a prepared knowledge base is not a certification. This site does not claim Scott holds a Six Sigma belt. His completed credentials are listed separately on the About page. Choose a method for the problem rather than collecting labels.
