DMAIC

Define - Measure - Analyze - Improve - Control

These five steps in a DMAIC project represent a structured roadmap used to improve existing processes. DMAIC projects strive to reduce variation and improve performance about a target.

Each project should follow this general roadmap to completion. Within each of these FIVE PHASES is more detailed information on the tools commonly used and the outputs that each will provide. A project begins with DEFINING the problem.

Each process phase should undergo a gate review before proceeding to the next. A gate review will ensure all the information and outputs are complete and prepared for the next phase. These reviews are done with the coach, sponsor, Green Belt (GB) or Black Belt (BB), Master Black Belt (MBB) and possibly the steering committee and upper management.

Don't panic because you can't use all the tools or if you don't think there is enough time to use all of them. Each project uses different tools and none will use all of them.

All the tools are there to use if needed; don't spend valuable time forcing the use of a tool when it isn't applicable. Each project is unique and the tools used will vary from project to project.

There is not a specified amount of time that each phase needs to be completed. Each project will vary on the amount of time spent within each phase.

A critical component of a GB's/BB's success is:

  • choosing the correct tools
  • in the correct order
  • and making the correct interpretations from them.

    Some tools are used in more than one phase and on more than one occasion. For example, Pareto diagrams can be applied in every phase and multiple times in some phases.

    The tools listed are not listed in exact chronological order or in order of importance as both may vary between projects.

    Roadmaps

    Within each phase are visual aids of the roadmap with typical inputs and outputs expected.

    Clicking on the links above will lead further into tutorials and materials on each topic.

    Not all topics for a continuous improvement program are shown as they are virtually infinite and evolving. These are simple lessons that are adequate for most projects.

    There are sample certification problems from each section to help you practice the key focal points of the DMAIC cycle. Click here.
