DMAIC is a data-driven, structured, customer-centric problem solving methodology. DEFINE tells you what to measure. MEASURE tells you what to analyze. ANALYZE tells you what to improve. IMPROVE tells you what to CONTROL.
Each phase has very specific objectives and is supported by a set of activities. Objectives for each stage should be satisfied and approved by project sponsors before the team progresses to the next stage.
All the tools in the VRI Toolkit will have one or more of the DMAIC Symbols in the title (see below). Choosing the right tool to use in your project can be difficult at first. The right tool can help you understand the problem you are trying to fix, analyze the data, and point to a viable solution.
