There are some very good points in this article. The first point about people or organizations that fail to seek outside help when it's needed is reasonable, especially coming from one who provides such services.

There is a flip side to this, particularly for larger organizations, however. That is some will seek outside professional help in defference to using the in-house talent they already have. Just because someone works for someone else, doesn't mean they are more knowledgable. Just because someone doesn't work for a consulting firm, doesn't mean they are ignorant or narrow in focus. It is quite often the case that a firm will have someone fully qualified to do the analysis and make the recommendations already in their midst but who is overlooked just because they are not an outside "expert." Indeed, much of the "advice" I've seen from outside experts is little more than shallow platitude, the solution du jour, or worn out rules of thumb that while valid, often fail to cut to the real issues that lie deeper within specific cultural, technical, or organizational complexity. Those issues often require much deeper knowledge than can be obtained in a six week or even a six month engagement.

So while outside expertise is a good thing to seek to ensure important ideas, practices, and principles are given full consideration, leaders may also be well advised to ensure those already within thier organizations that are capable are given the mandate and opportunity to contribute to their fullest in the development of new strategies or the resolution of difficult problems.
