It depends on the problem you're solving! In a former job, I worked for a consultancy that would be called in to solve industrial problems. Our strategy was to use first principles to truly understand how to best affect the metric we were trying to change- and it worked beautifully, and we built our entire business around it. Yes, we had to hire smart engineers, but not necessarily geniuses- because the problems we were solving weren't "how do I lower the cost of car ownership in this country," they were more like "why has the efficiency of this naphtha recovery plant decreased by 25% over the last year and how can we fix it?"
(I'll note that the fact that we were being called in constitutes a type of selection bias- the "typical" methods of solving the problem weren't working.)
