A methodology for the development of new services, products or processes (as opposed to improving existing ones) that aims at ensuring that they achieve Six Sigma quality.

DMADV is composed of 5 distinct phases: 1) Define - the problem, the goal and the customer's needs, 2) Measure - identify the parameters that must be quantified, how to measure them, then collect the data, 3) Analyse - the options and develop design alternatives, 4) Design - the chosen alternative using results of the previous step, and 5) Verify - that the design will work in the real world, and begin production/sales.
