GrowAdaptationYour Best People Aren't the Product. What They Know Is.
4 September 2026
I’ve grown more than one consulting business on the simple premise of headcount. More consultants, more billable hours, more revenue. For most of my career, that formula wasn’t something I questioned, it was just how growth worked.
A wiser man than me once put it plainly: “The currency of professional services is billable hours, Rob.” At the time, I could only agree. It was the foundation everything else sat on.
But that’s changing, and changing fast. I had a conversation this week with one of my client’s own clients that made the shift impossible to ignore. Their message was blunt: “We don’t want your time. We want your knowledge. Help us make the boat go faster.”
That’s the whole argument in one breath, and it came from someone with no reason to dress it up for me.
The deliverable got cheap. Nobody said what replaces it.
The industry’s public story about AI is mostly a productivity story. Faster research. Faster drafting. Faster delivery. All true, and all beside the point.
The real story is that producing the traditional deliverable, the report, the integration, the migration, the analysis, is becoming radically cheaper across the board. Not just at the firms with the biggest AI budgets. Everywhere. What used to take a team of five three months now takes a smaller team three weeks, sometimes less, and next year it’ll take less again.
That should terrify anyone whose business model is still “we sell hours.” It should also be the best news growth-minded firms have had in a decade, because cheap production was never actually the constraint on growth. Access to it was.
Cheap delivery is an access problem solved, not a value problem created
I’ve watched this pattern play out inside more than one of the businesses I’ve run or advised. The instinct, every time, is to get faster at the same thing: shave the delivery time, hold the price, call it a margin win. That’s not nothing, but it’s not the real move either. If you want live examples of who’s actually rebuilding the model rather than just speeding it up, my reading list has a few worth a look this week. The interesting ones aren’t just delivering faster. They’re using cheap delivery to profitably serve clients who were priced out of expert help altogether, and that’s where the growth actually is.
The pattern underneath all of them is the same: stop treating expertise as something that gets consumed once per client and disappears, and start treating it as something built once, then sold again and again.
Selling the hour was never the point. It was just the only unit you had
Here’s the uncomfortable part. Most services businesses aren’t set up to make that move, because everything about them, the pricing model, the org chart, the way senior people spend their time, was built around a single unit of sale: the billable hour.
The billable hour made sense when expertise could only travel inside a person. If the only way to deliver what you know was to have a smart human sit in a room and apply it, then of course you priced by the hour. You were selling access to a scarce brain, one conversation at a time.
That constraint is gone. What a senior consultant knows, the pattern they’ve seen forty times, the diagnostic instinct, the “here’s what actually breaks in year two” judgement, can now be captured, structured and delivered by something that isn’t a person sitting in a room. Not perfectly. Not without oversight. But well enough that the billable hour stops being the only unit you can sell.
I’ve read and re-read David Maister and Ronald Baker on this for years. Maister was making the case in Managing the Professional Service Firm, back in 1993, that once utilisation is reasonable, chasing more hours stops making sense, the real lever is the value you’re realising, not the volume you can bill. Baker went further, building an entire movement out of pricing on value delivered rather than hours worked at all. Between them, the argument against the billable hour has been sitting there for over thirty years.
This isn’t a new idea. Most of the industry just never bothered to pay attention.
The billable hour was still the only unit you could reliably scale, so however persuasive the case against it, most firms kept the scorecard they had and got on with it.
That excuse is gone now. The good news is the tyranny of the billable hour really is ending. The bad news is we now have new challenges, and most firms haven’t worked out what they are yet.
Perform used to mean utilisation. It doesn’t anymore.
Every professional services business I’ve run or been close to has tracked the same three numbers religiously: utilisation, average bill rate, headcount. Get all three moving in the right direction and the P&L takes care of itself. That was the scorecard, and for a long time it was the right one, because the hour really was the unit of production.
None of those numbers mean what they used to.
Utilisation measures how busy people are, not what they’ve built. Chase it hard enough in a world where the deliverable is getting cheaper, and you’re rewarding your best people for staying busy re-doing something that shouldn’t need doing from scratch a fourth time. Average bill rate measures what you can charge for an hour of someone’s time, in a market where the hour itself is worth less than it was last year, and will be worth less again next year. Headcount measures how many people you need to do the work, at the exact moment AI is quietly reducing how many people a given piece of work actually requires.
Keep managing to that scorecard and you’ll optimise your way into a smaller share of a shrinking pie. Efficiently.
The replacement scorecard looks different. How much of what you deliver this year can you deliver again next year without adding headcount. How much of your revenue comes from something you built once, rather than something you’re doing again for the first time. Whether your best people are spending their time creating reusable IP, or still getting consumed one client at a time, the same way they were a decade ago.
That’s an uncomfortable set of numbers to start tracking, because most firms don’t have good answers to them yet. But it’s the actual scorecard for the business this piece is describing, and utilisation isn’t on it.
From billable hour to durable asset
So what do you actually own, once the hour stops being the product? For most firms, the honest answer right now is: nothing. The knowledge lives in people’s heads, in old proposal decks, in the memory of whoever ran the last three engagements. It’s real, it’s valuable, and it evaporates the moment that person leaves or gets busy on something else. That’s not an asset. That’s a liability wearing an asset’s clothes.
Turning it into an actual asset means doing the unglamorous work of getting the pattern out of the expert’s head and into something repeatable: a workflow, a diagnostic, a decision framework, a productised offer that doesn’t require your best person in the room every time it’s delivered. It means being honest that most of what your senior people do for a client isn’t actually bespoke, it just felt bespoke because nobody had bothered to write it down and package it before.
That’s harder than it sounds, and slower than the AI headlines suggest. It’s also the only version of this story that ends in growth rather than a slow, well-managed decline. A firm that gets faster at selling the same hour is still selling hours, just cheaper, into a market where everyone else is getting cheaper too. A firm that turns what its people know into something it can sell without needing that specific person in the room has built something the first firm doesn’t have: a product.
Your best people were never really the product. They were the only available packaging for something more valuable underneath: what they know. AI is the first technology that’s ever made it possible to ship that without the packaging attached.
The firms figuring that out first won’t be competing on rate cards anymore. They’ll be selling something the rate card was never built to price.
