I would say the director's comment is misdirection with a core of truth.Yes, McKinsey has had the Business Technology Office for ages, BCG has an IT strat division etc.But - there is a huge gulf between this and what constitutes tech consulting at Big 4, however. If you think of it as a venn diagram, there'd be a sliver of overlap. The majority of Big 4 tech consulting is implementation and systems integration, which is out of scope for MBB - what is in scope is consulting at senior management level on tech strategy, tech enabled operations/marketing etc. in the same way as any other non-tech related strat/ops/marketing project.The core business of traditional strat houses is management consulting - high level concepts, decks, benchmarks, and yes, now proprietary tools/solutions.The core business of Big 4 is audit/systems integration/outsourcing, with management consulting done as a way of either selling on other business or to market themselves as a 'one stop shop'. This is not to say that their management consulting arms are poor or can't compete, but that their strategic commercial aim is not really the service they themselves provide.
