It also expresses the Y as a measurable process metric that tells how well the process is performing today (the baseline) and how performance should be after process improvement (the goal). The project charter delivers the Y by clearly stating what the business or process problem is. Handpicked Content: Using Six Sigma to Reduce Pressure Ulcers at a Hospital Multiple tools are used during the Define phase to get a clear understanding of the project Y (i.e., what the process problem is in measurable terms and what the project goals are). It is obvious that something has to be done, but where exactly to start and what exactly to achieve is often only poorly described. Many projects start with a rather unspecific and undefined business or process problem.

Control: Monitor important x‘s and the Y over time.ĭefine: Understand Project Y and How to Measure It.Improve: Implement solutions to improve Y and address important x‘s.Analyze: Test x– Y relationships and verify/quantify important x‘s.Measure: Prioritize potential x‘s and measure x‘s and Y.Define: Understand the project Y and how to measure it.Each DMAIC phase can therefore be described by how it contributes to this goal: The goal of DMAIC is to identify which few process and input variables mainly influence the process output measures.

The mathematical term Y = f(x), which translates as simply “ Y is a function of x,” illustrates the idea that the important process outcomes ( Ys) are a result of the drivers ( x‘s) within processes. Y = f(x): Process Outcome a Result of Process Inputs Here is the Y = f(x) story, phase by phase. An excellent way to overcome this problem is to always keep the concept of Y = f ( x) in mind when applying specific tools along DMAIC phases. In the worst case, Green Belts and Black Belts are just completing templates and do not achieve the desired outcome of a significantly improved process. Each tool is used separately and sequentially rather than in the context of the overall purpose of the DMAIC approach.

All well and good, however, inexperienced or newly trained Green Belts and Belt Belts tend to lose themselves in the application of individual tools. The related toolkit is a selection of proven tools and methods that– correctly applied – helps to determine, analyze and improve a problem. With its DMAIC (Define, Measure, Analyze, Improve, Control) roadmap, the Six Sigma methodology provides a structured and systematic approach to solve business and process problems.
