Does that sound like a good idea to you? It doesn't to me, yet so many of us do it. Our instincts are to look back before we go forward, and ask what we did before, and what we need to do to change (for preference, as little as possible)? We organize our businesses to be accountable in narrow silos. We set incentives the same way; we define goals within tight guard rails and reward those who execute on those goals often out of proportion to our collective objective.
