Key differentiators between top strat houses and others:1. The consultants themselves. Let's face it, McK and the 3Bs attract, hire, and compensate differently from the Big 4 and others. 2. There is a difference in the type of work. John, are you privvy to the work McK, Deloitte, and Booz at BP such that you know what they're doing is truly "similar"? Have you seen the "letters of engagement" or reports? I've been on 2 projects where the client hired multiple consultancies seemingly on the same issue, but really different engagements. One involved 3 MC firms working on "profit improvement". Seems the same right? But McK was doing growth strategy, ATK was doing sourcing, and Deloitte was doing BPR. Another involved a merger where 3 MC firms were working on "post-merger integration". Same thing right? Except that McK was managing the overall PMO, ATK was doing sourcing, and PwC was doing the due diligence.Of course, it's entirely possible that BP truly hired 3 MC firms to do EXACTLY the same thing (possible, but unlikely). If they did, that would be a serious misuse of company funds and not representative of most "profit-constrained" companies.3. Brand, prestige, and consulting fees are such that a client would be hard pressed to hire McK/3B's for any work other than the most strategic in nature. Have any of you guys seen an unsatisfied and disgruntled ex-McK, Bain, or BCG consultant on this or any other Board? This, In spite of the fact that strat houses are known for working insane hours, live their life on the road, and all practice an "up-or-out" philosophy (i.e., the bottom 10-15% are culled annually)? Have you guys stopped to think why? On the other hand, how many unhappy Deloitte, PwC, EY, CG, etc. consultants do you guys see on this Board?
