The 2nd step of the Six Sigma problem solving methodology is the Measure step. An operational definition clarifies What, How and Who is going to collect the data so that the team is in agreement. Process analysis and mapping A process is a set of interrelated resources and activities which transform inputs into outputs with the objective of adding value. The activities relative to any process of importance, should be documented and controlled. After this step we need to see what data is required to establish the relationship between each X and Y.

The letters in the acronym represent the five phases that make up the process, including the tools to use to complete those phases shown in Figure 1. It is an integral part of a Six Sigma initiative, but in general can be implemented as a standalone quality improvement procedure or as part of other process improvement initiatives such as lean.

Project charter to define the focus, scope, direction, and motivation for the improvement team Voice of the customer to understand feedback from current and future customers indicating offerings that satisfy, delight, and dissatisfy them Value stream map to provide an overview of an entire process, starting and finishing at the customer, and analyzing what is required to meet customer needs Measure process performance.

Process map for recording the activities performed as part of a process Capability analysis to assess the ability of a process to meet specifications Pareto chart to analyze the frequency of problems or causes Analyze the process to determine root causes of variation and poor performance defects.

Failure mode and effects analysis FMEA for identifying possible product, service, and process failures Multi-vari chart to detect different types of variation within a process Improve process performance by addressing and eliminating the root causes. Design of experiments DOE to solve problems from complex processes or systems where there are many factors influencing the outcome and where it is impossible to isolate one factor or variable from the others Kaizen event to introduce rapid change by focusing on a narrow project and using the ideas and motivation of the people who do the work Control the improved process and future process performance.

Quality control plan to document what is needed to keep an improved process at its current level Statistical process control SPC for monitoring process behavior 5S to create a workplace suited for visual control Mistake proofing poka-yoke to make errors impossible or immediately detectable DMAIC vs.

The DMADV method or approach is often used when implementing new strategies because of its basis in data, its ability to identify success early, and its method, which requires thorough analysis. Quality Progress Identify when you need a structured method for problem solving. Featured Advertisers.
