Hi, I know what the immediate responses are going to be: ' no deloitte strat is a tier 2, tier 1 is only Mck, Bain, BCG etc etc'I want to probe further. I think what we define here as tier 1 / 2 etc oftentimes is a defenition of the BRAND - not of the type of work or client base.Of course i agree that Mckinsey has outstanding people and delivers superb work. However - is it greatly superior to that of a Deloitte of a Roland Berger? Dont they deliver the same work for same clients just calling it differently?Take BP for example: at any given point in time there are several of the top consultancies in thier london offices. Accenture is there, Booz is there, Deloitte and Mckinsey.But if you look closely, McKinsey's 'growth strategy' is a very similar to Deloitte's 'fundamental business review' - which in turn is similar to Booz's revenue analysis etc etc. So my question to you: are the tiers that we so often obsess about created by success and innovation of delivery or are they solely about prestige and brand. ( and thus higher fees)??
