1000 times this. Any management system is only as good as its practitioners. The most talented managers and leaders tend to be good communicators, and so there are hundreds and thousands of great books on management philosophy, systems, tactics, etc. But all of it is subject to cargo culting by people who simply lack the experience or skillset to successfully follow the advice. At the end of the day, unless you have a quorum of leaders who viscerally understand what is meant by the old adage "the map is not the territory", then you are doomed. This is why leaders should be drawn from experienced practitioners, MBA programs should require 5+ years industry experience before admission, and Finance should not be let anywhere near product decisions (other than to set a budget).
