Brian Miller wonders if Six Sigma can be used in a non-traditional setting, like a church. I'm not any kind of expert here, but it was a fun exercise to see how flexible the concepts could be. The reason I think they're so relevant to marketing is that the underlying concepts are pretty simple.
The article goes on to apply DMAIC to a church environment. I am learning more about Six Sigma myself, but why not apply to other types of organizations.
From what I understand, the idea behind Six Sigma is not so much reducing the number of manufacturing errors to one in a million, but to instill a culture of continuous improvement within the organization. The books talk about applying Six Sigma principles to service as well as to manufacturing.
