Hmm, it sounds like a 'supreme court' of engineers.

I have a couple of concerns. Not limited to those already raised.

Apart from the recognition attached, which healthy engineers probably don't rate very high up their list of needs, I don't see much advantage to being on the DNA team/board. Good engineers want to create, not clean up after others. The engineers on a good DNA team need to be motivated as a manager is, by wanting to contribute not to the product portfolio, but to the team portfolio. That switch in motivation is going to be rare in itself.

I worry that the vast majority of people striving to achieve DNA status would be doing so from motives other than is healthy for the team or the organisation as a whole.
