Every sector is a buyer. None of them is your market.

Open the website of almost any environmental consultancy between ten and a hundred staff and you will find the same page. Sectors we serve: oil and gas, mining, infrastructure, residential development, local government. Sometimes agriculture. Sometimes defence. Eight tiles, eight stock photos, and under each one the same services offered on the same terms. The page is meant to say we can help anyone. What it actually records is everyone who has ever paid an invoice.

The instinct behind the page is sound, which is why nearly every firm has one. Each sector on it is a real buyer with approvals to win and conditions to meet. Turning one away feels like turning away revenue, and a wide net feels like insurance against a downturn in any single market.

But the page answers the wrong question. Where the work has come from is history. Where the growth will come from is a choice, and breadth makes that choice for you, badly, in two specific ways.

What breadth costs

The first cost lands on sales. Consulting firms grow on referrals, and referrals travel inside sectors, along the grain of an industry. A quarry manager whose expansion just cleared approval first go, or whose new treatment basin quietly took a standing task off the crew, tells other quarry managers, at the same conference, in the same association, in the same group chat. They do not tell a residential project director, because they have never met one. Spread the delivery across five sectors and you are seeding reputation in five separate rooms. In each room you are an occasional name. In none of them are you the firm people recommend without being asked.

The second cost lands on the product. Across sectors the service names look identical: erosion and sediment control, contaminated land, ecological assessment. The needs underneath the names are not identical, and those differences are exactly where a service either sharpens into something distinctive or stays generic. A firm serving everyone has to average across the differences. Averaging is how a firm ends up credible in every market and the obvious choice in none.

That claim deserves to be earned, so let us pull one service apart.

One line on the services page, three different jobs

Take erosion and sediment control, a line that appears on nearly every environmental services page in the country. Point it at three different buyers and watch it turn into three different products.

A quarry is a static site with a long life. The pit will be worked for twenty or thirty years, the disturbed footprint is permanent, water reports to the same low points after every rainfall event, and it leaves the site through a fixed discharge point with licence conditions attached. That combination rewrites the economics of treatment. A serious engineered asset at the discharge point, a designed basin with automated dosing and continuous flow treatment, is entirely rational here: the capital amortises across decades of operation, and it buys the two wins this buyer actually talks about. Expansions clear approval first go, because a regulator looking at a controlled, monitored discharge has little left to argue with. And the labour line shrinks, as continuous dosing retires a standing manual task the crew used to chase through every wet season. The conversation is about growth and operating cost, and there is genuine appetite for capital that buys both.

A residential development is the opposite site. Nothing is static. The works move through stages, every control is temporary, and every dollar spent on controls comes straight off lot margin, on a program where a fortnight’s delay costs more than the controls do. A permanent engineered asset makes less sense here, and even where the approval still calls for one it is a cost to minimise rather than the centrepiece. This buyer wants the cheapest defensible path to compliance: a staged plan keyed to the civil program, low-cost controls that can be installed, shifted and removed as the stages turn over, and an inspection regime that keeps the regulator satisfied without ever stopping the earthworks.

A road authority is different again. The site is a corridor, the works are cut and fill in short runs along a chainage, and staging as a residential contractor would understand it is often simply unavailable. Procurement arrives with a score attached. On the large road and infrastructure jobs the head contractor is chasing an ISCA sustainability rating, and there is a bonus riding on hitting it, so a criterion favouring recyclable or low-impact materials carries real commercial weight. It looks minor in the tender documents and is decisive in the design, because it removes whole categories of control from the table and pulls others in. The plan that satisfies this buyer is shaped as much by specification and auditability as by the dirt itself.

“Same line on the services page. Three different products underneath.”

Same line on the services page. Three different products, three different buying logics, three different definitions of good. A firm serving all three at once has one honest option: write plans generic enough to pass in each market. And generic enough to pass is a ceiling. Every client can feel it, including the ones who could not name it.

Small differences, large consequences

The pushback writes itself: these are details, the core discipline is the same, a competent consultant can flex between them. All true, and all beside the point, because in consulting the details are the product. A materials mandate is one line in a specification, and it reshapes everything installed along a five-kilometre corridor. A staging constraint is one sentence in a brief, and it rewrites the sequencing logic of an entire plan. What reads as a minor difference in needs is routinely the difference between a solution the client accepts and a solution the client renews.

There is a real version of the objection, and it is worth being honest about. Pay for genuine A-listers and they can work each case out from first principles, bespoke, every time. It is also the most expensive way a firm can run. The margin sits in the gap between what those people cost and what the client will pay, and bespoke brilliance keeps that gap thin. The firm that has turned its market knowledge into systems gets the same result from good people who are not the most expensive in the state, and it keeps the difference. Good staff produce A-list work because the system carries what it should, and the firm stops depending on heroics that never scale.

And the differences keep resolving. Sectors behave like coastlines: measure with a shorter ruler and there is more coastline. This is the fractal nature of knowledge, and it does not run out. Look at quarries as a class and you see one set of needs. Get closer, to hard-rock quarries in a wet-season climate, and another layer of jobs and problems appears: geology that changes which treatments behave, regulators whose officers inspect particular things, failure modes that only show up in the third summer. Each layer you can see is a job you can build the service around, and the generalist never gets close enough to see past the first one. Depth of understanding is the one input a competitor cannot buy quickly, which is what makes it worth owning.

The flywheel only spins in one market

Put the pieces together and a loop starts turning. You build for one buyer, so the fit is better. The fit is better, so the outcomes are better. The outcomes travel, and they travel inside the sector, where your next ten clients are already listening. The new work is more of the same, so every job deepens the understanding, which sharpens the product again. Marketing gets easier for the same reason: you can name the buyer’s problem in the buyer’s own words, and they conclude, correctly, that you have solved it before. A sharper fit is also the position from which pricing on worth rather than hours becomes possible, because you finally know the buyer well enough to know what the outcome is worth to them.

The gains are not only in sales. Repetition is what makes delivery predictable too. When your people have run the same kind of job twenty times, over-runs stop being a fact of life and become rare, because nobody is solving it fresh. Estimating turns programmatic in the same way: you learn what actually drives cost in this work, and you can write simple rules that price it consistently across clients and projects, instead of building every number from a nervous blank page.

None of this is available to the firm spread across five sectors. The loop needs repetition in a single market before it will close, and breadth is a standing decision never to repeat.

Two ways to narrow

Narrowing does not have to mean picking a sector, and this is where the two axes matter. A discipline specialist takes one service deep into many markets: the firm that does erosion and sediment control, and little else, for anyone with disturbed ground. An end-market specialist takes many services deep into one client type: the firm that handles everything a quarry operator needs, from first approval through to closure. Both are focus, pointed at a different dimension, and both escape the generalist’s averaging problem, because each one repeats. The discipline specialist sees the same service so often that its every failure mode is familiar; the end-market specialist sees the same buyer so often that their whole world is.

How you go about each is different. As a discipline specialist, pick the one service you are already best at, take it to every market that has the problem, and set out to become the name people reach for when that problem is the hard part of the job. As an end-market specialist, pick the client type whose business you understand best, and build outward from a single service into the full arc of what they need across a project’s life. The worked example earlier narrows on both axes at once, one discipline pointed at one end market, which is where the fit is sharpest and the market is smallest. Where you land is a sizing decision as much as a positioning one: the niche has to be large enough to feed the firm you intend to run.

And if you are the firm doing many services for many markets today? The honest advice is do not stay there. But you do not have to burn the website down on day one. Leave the shopfront alone and change what happens behind it: pick one service and one market, and go deep. Build the product, write the templates, win a few jobs, and collect the referrals that only a focused reputation earns. Let the focus prove itself in the numbers before you rebuild the site around it. Narrowing is a direction you commit to and grow into, one job at a time.

The evidence for the choice is already in the building. Run a Pareto read over the job ledger: where margin and repeat work concentrate, which clients came back without a tender, which sectors produced the jobs your best people still talk about. Firms rarely need to invent a niche. Most need to notice the one their own numbers have been pointing at for years.

From product to template to institution

A narrow market pays one more dividend, and it is the one that compounds longest. When the needs are homogeneous, the deliverable can be standardised, and once it can be standardised the firm can stop relying on each consultant’s private version of how the work is done. That is the current state in most firms: Sarah pulls up the last report she wrote, Harry pulls up his, the two have been drifting apart for years, and the firm’s method is whichever file got opened.

The fix is a pair of documents for each product. The first is the template: the deliverable’s skeleton, with the structure settled, the standing text argued over once and locked, space for the data, and the recommendations that are genuinely standard written in line. The second is a guidance document keyed to it section by section: how to actually produce each part, at whatever level of detail stops the reinvention. If a section calls for a plan, the guidance holds the stepwise method for building one, down to where the files live and how to georectify the base image.

I learned what that second document is worth early in my career, in Cairns, when a manager handed me a handwritten procedure. Seven steps for georectifying an image in ArcGIS: which menu, what a control point was, where the imagery sat in the company’s file structure, the order of operations that dodged the software’s traps. The person who wrote it had left the firm four years earlier. The page was creased soft from being passed from desk to desk, and it worked every time. I did not have the language for it then, but I was holding institutional knowledge: one person’s hard-won method, captured well enough that it kept doing its job years after its author had gone.

That is what a template and its guidance are, at the scale of a whole product. Every improvement a consultant discovers has somewhere to land, so the next project starts from the firm’s best current version rather than one person’s memory of it. New starters become useful in weeks because the method is on paper. And the know-how stops resigning when people do, which matters well beyond delivery: a firm whose method lives in documents rather than heads is a firm that is worth something without its founder in the room.

The template is also where quality stops being a slogan: the product’s definition of good, the one this buyer holds, written down where the work happens. Most firms define quality once, at company level, and it collapses into on time, on cost, to scope. That trap is its own article.

The chain

One warning before the chain sounds free. Templates and guidance take real hours to build, and those hours are never billable. They belong in the same deliberate allocation as every other piece of future work the firm does, with a bucket, a budget and a sponsor of their own. Firms that treat this as spare-time work end up with templates that are three years stale, which is worse than none, because people trust them. And building them is only half the cost; keeping them current takes its own discipline. The firms that manage it treat their templates and guidance like code, versioned and reviewed, so anyone can propose an improvement and nothing changes without a set of eyes on it. That is a subject for another day.

Describe the buyer, then go looking

Choosing to narrow is the first decision. The second is turning the choice into a description sharp enough to act on. Write down the operation’s size and situation, the trigger that makes them buy, the approval or licence pressure they sit under, what they have usually tried before calling anyone, who signs, and what that person is judged on. The test of the description is practical: could someone outside your firm take it and pull a list of a hundred operations that match? If yes, you have an ideal customer profile and a market you can scan for lookalikes, sized, prioritised and approached deliberately. If no, you have a preference.

That scan, sizing the market, reading the competitors, building the target list, is its own piece of work and the next article in this stage. The narrowing has to come first. You cannot describe a buyer you have not chosen, and you cannot choose while the services page is still promising every sector that the firm was built for them.
