LEADERS IN CONSULTING

The episode offers some substantive observations about consulting industry transformation driven by AI, particularly the shift from generalist to specialist models and the decline of long-term, large-scale team deployments. However, much of the content consists of Purnell elaborating on his own business practices and philosophy rather than introducing densely packed novel ideas. Several segments (COVID response, talent development, personal interests) dilute insight density with narrative rather than actionable frameworks.

“the dependency that companies had on getting very good quality um humans into companies to help manage change, uh it it that that that that model is no longer a model that's going to suffice um for the years ahead”

“AI has commoditized that. So I think if you're a generalist firm, uh if you're a small generalist firm or even an enormous generalist firm, I think you've got some serious problems on your hands”

Purnell's core thesis - that consulting is moving from scaled delivery to specialized advisory, and that AI will disrupt generalist business models - is not particularly novel. The comparison to architects' practices and the "fixed fee for fixed scope" model are borrowed analogies. The multi-generational talent strategy and investment in junior talent show some originality, but the broader frameworks are well-established consulting industry wisdom.

“the model of consulting has changed um and will continue to change”

“I describe our business more like an architect's practice, actually”

Olly Purnell is a highly qualified guest with 31 years in consulting, 17 years building Q5 from five people to 300+ across eight offices, achieving consistent 20%+ growth, and demonstrable operational success. He speaks from direct experience running a specialist consulting firm and has navigated major industry transitions (newsrooms, COVID, AI). His track record is substantive and relevant, though he is not a household name outside consulting circles.

“I have been in the world of consulting for 31 years now”

“We set it up as a small little five-person business focusing on what we called organizational health, uh, which is all design and development and looking at structures and spans and layers and people. And that has grown over the last 17 years. So we're now in eight offices around the world, and we have just over 300 employees”

The episode contains some concrete details (Q5's 8 offices, 300+ employees, 160 clients/year, 20%+ growth, 8-12 week project cycles, 987 youth panel applications, 15 selected). However, many claims lack hard evidence: the assertion that big four consultancies are struggling relies on anecdotal observation and Accenture stock price rather than data; the claim about consulting firm growth in the UK is stated but not substantiated; specific client transformations and metrics are largely absent; the 'There's an AI for that' app is mentioned but not verified.

“we're now in eight offices around the world, and we have just over 300 employees across those different offices and work with about 160 clients a year”

“our own company grew at the rate of over 20% in the lot in the year just finished last month”

Sarah Edwards asks good framing questions and demonstrates knowledge of consulting models, but rarely challenges Purnell's claims directly or pushes back on assertions. She allows him to set the narrative and extend into tangential stories (music, COVID response, personal AI use) without redirecting. A few moments show genuine follow-up ('What's driving that increase in demand?'), but overall the conversation reads more as a platform for Purnell's perspective than a rigorous exploration. Missing are harder questions about survivorship bias, contradictions in his claims, or pressure-testing his predictions.

“What pushed you to do something different?”

“what are some of the signs then? You know, there's still a lot of consulting firms out there that I think are running in that generalist way”
