I am considering joining a botique outsourcing advisory firm who provide consulting services across the whole sourcing lifecycle (sourcing strategy, supplier selection, contract negotiation, project management, health-check, the whole works!). My long term plan is to gain enough experience in this market and jump to a MBBB. My understanding is that these top strategy consultancies also provide such services. Does it sound like a plausible plan? How well are the top firms doing in this specific domain of consulting?
