Defining Design for the Six Sigma Process
DMADV a.k.a. DFSS
The DMADV project methodology, also known as DFSS ("Design For Six Sigma"),[12] features five phases:
* Define design goals that are consistent with customer demands and the enterprise strategy.
* Measure and identify CTQs (characteristics that are Critical To Quality), product capabilities, production process capability, and risks.
* Analyze to develop and design alternatives, create a high-level design and evaluate design capability to select the best design.
* Design details, optimize the design, and plan for design verification. This phase may require simulations.
* Verify the design, set up pilot runs, implement the production process and hand it over to the process owner(s).
In order to scope out a potential project its imperative one understands the Six Sigma DMAIC requirements. A great example of project scoping is similar to a physician diagnosing a patient with a specific illness. Effective project scoping is also comparable to a physician treating a patient with a specific illness, attention to detail is important when diagnosing a patient (Lynch, Bertolino, Cloutier, 2003). The define phase of a six sigma project is one of the most vital phases. The define phase can have the most impact on the success of the project.
The DMAIC Six Sigma methodology should be used when a product or process is currently in place, but for some reason does not meet the customer specification or is not performing effectively, The DMADV methodology should be used when a new product or process is being introduced, when a process does not exist, or has reached entitlement. If a defect exists, one should opt toward using the DMAIC methodology to complete a six sigma project. Due to the nature of this process, identifying the customer specifications, designing and optimizing solutions, implementing the new process, product or service, a DMADV project can be more complex and be potentially longer in duration. Some Black Belts may be tempted to defer to
