Analyse
Analyze phases are when teams perform detective work on the process.
Tools common in the Analyze phase include Pareto charts, run charts, histograms, cause-and- effect diagrams, scatter diagrams, process maps, and value analysis.
Control is the final phase for Six Sigma teams employing the DMAIC process. During the Control phase, teams usually handle four tasks: creating the foundation for process discipline, finalizing documents regarding the improvement, establishing ongoing metrics to evaluate the process, and building a process management plan that lets the team transition the improvement to the process owner.
The charter usually features a list of team members, names of those responsible for outcomes, a problem statement, a goal, and some basic definitions of scope and metrics for success.
teams create what is known as a project charter and a basic plan for work. A charter is a synopsis of the project.
teams create or list measurable customer requirements and create high- level documents about the process
Usually, the transition between phases is marked by a tollgate review wherein the team presents its Define work to a champion or a Six Sigma leadership board.
During the Measure phase, the team is concerned with creating a baseline metric for the process and refining problem statements and other outputs of the Define stage.
One of the biggest challenges, especially for teams and team members who are new to the Six Sigma method, can be deciding what to measure.
It can be hard to determine which solution actually improves a process, however, so it’s usually a best practice to implement one change at a time and verify that change before moving on to something else

Closing a DMADV Project
One of the major differences between DMAIC and DMADV is the possible timeline. We previously stated that a problem fits the DMAIC model if it can be solved in less than six months. While some DMADV projects might only take a few months, many process or product designs can take years.
