I work in the federal and State government market - often called "beltway bandits" and often for good reason. In my 25 years in consulting in this market, I would guess that about 70% of the consulting firms and people will say they can do something that they have no idea how to do or that they have only a cursory knowledge about.

Let's face it, most of us do well in the field because we can read and understand how to do something that our clients often cannot comprehend or do not have the time to learn. Unfortunately, most consultants that over-extend their skills do not understand the implications or ramifications of decisions made.

There certainly are nightmare clients that no one can please but if you are part of the problem, then the client is better off without you.
