DMAIC:
This analytic tool set uses a five-step process to help an organization's processes reach levels of performance never before seen. DMAIC stands for Define, Measure, Analyze, Improve, and Control.
DMADV:
DMADV is an analytic tool set used when an organization needs a new product, process, or service. Using this tool set, Black Belts optimize performance before production begins, making this tool proactive, as opposed to reactive like other tool sets like DMAIC. DMADV stands for Define, Measure, Analyze, Design, and Verify.
There is another tool set DMADDD which is not mentioned in Selina's content. So it is no need to publish it. Otherwise it may cause some confuse.
