The essence of consultancy is simply stated, and you should never fail to bear it in mind. You are there to do the dirty work. It is therefore essential you never make the elementary mistake of supposing for a single moment that any of your careful recommendations will necessarily be put into effect. To believe that is to misunderstand the true nature of the consultancy business. Being a consultant means being an expert in a field which you have yourself invented, namely that of telling people who have been doing a job for years that you know how to do that job better. A bluffer is somebody who pretends to do all this, which comes to very much the same thing in the end.
Consultancy has become a euphemism for the state of being unemployed. This book is not for such people, who have brought consultancy a bad name. It is for those who actually seek to earn a living from consultancy, without knowing the smallest thing about it. In other words, for bluffers.
Bluffer's Guides is a series of snappy little books containing facts, jargon, and all you need to know for instant expertise.
