idk, avoiding landmines seems like pretty significant business impact
the exception was places where leadership already thought in the same terms about software quality/etc, which meant I didn't have to do much convincing :P
how would you build teams or structures to support that sort of holistic thinking about software?
this is why i advocate the engineer/manager pendulum so strongly. we get better results when management has strong tech skills (and staff+ engineers have organizational skills as well).
