Sound great for a non-technical company. In the drier example they give, the GM is able to understand the initial symptoms, follow the chain of inference, and identify the root cause.

Before you say that tech companies should be run by hackers, consider that even unfamiliarity with a sub-project can make an otherwise competent techie give retarded advice.
