Thoughts on DMAIC and DMADV
DMAIC is an integral component of Six Sigma. It is a systematic, scientific and fact based approach which aims to provide a rigorous and tenacious structure of results-oriented management. While DMAIC's methodology may seem to be thoroughly defined and linear, it is important to understand that the best solutions from DMAIC are derived when there is flexibility in the process, which would thereby eliminate measures that are unproductive. A consistent and monotonous approach may be essential as well, especially in circumstances in which the team members are not very familiar with the specfic tools and methods.
DFSS' DMADV is a fairly expensive, longer-term and resource driven process, which means that its deployment should be done meticulously and with care. It should be used on a few important projects which are particularly aimed at developing new products. It is absolutely vital to note that a DFSS project should not be started without the interaction with the customer, the involvement of the sales department, commitment of top management and preferably a team with Six Sigma training. Primarily, DFSS is for the development of new processes and products. It is a powerful technique, which requires to be led by a trained Black Belt or Master Black Belt.
