Match the description of each phase of the Lean Six Sigma method used with NEW processes: Design, Control, Verify, Define, Improve, Analyze, and Measure This phase is when teams use data to validate their assumptions about the process and the problem. During this phase, the team works to create a new process which includes some solutions testing, mapping, workflows, and new infrastructures. This phase is concerned with identifying the problem, defining requirements for the project, and setting goals for success. This phase is where loose ends are tied and the project is transitioned to a daily work environment. During this phase, teams develop hypotheses about causal relationships between inputs and outputs and between Xs and Ys, they narrow causation down to the vital few, and they use statistical analysis and data to validate the hypotheses and assumptions they've made so far.
