How does a technical services firm actually grow?

In the first piece I argued that technical services firms stall for lack of a consistent approach or system. Before getting to what that system could look like, two questions decide everything downstream: what business development actually is, and what growth in a technical services firm rests on. Skip them and even a well-built system is pointed at the wrong thing.

Business development starts from strategy

Let us start with the term itself. Business development is the structured approach that converts strategy into opportunity, by identifying, shaping and pursuing work that creates value for clients and sustainable growth for your firm. Notice that strategy comes first. There is nothing to convert until the firm has decided where it is going. A clear strategy is what business development serves, and it is what informs the criteria every later decision is judged against: which sectors to focus on, which opportunities to qualify in or out, which pursuits deserve real effort, which clients you want to work with. Without it, business development has no compass, and every decision becomes a matter of opinion, usually settled by whoever speaks loudest in the room.

Strategy does not have to be elaborate. It has to answer a handful of questions: where do we play, who do we serve, what do we want to be known for, how do we win, and what will we not do. Often the answers are half-formed and carried in the founders' heads, and that is usually where business development gets confused. They do not have to be perfect or final. They have to be clear enough to guide a decision when an opportunity lands.

Growth rests on service, trust and visibility together

With a strategy to point the way, growth in a technical services firm rests on three foundations that have to be present together: excellent service, trusted relationships, and visibility.

Excellent service is the minimum requirement and what clients come back for. In work that is bought on judgement rather than specification, the quality of what you deliver is the strongest argument you will ever make. It does not mean going above and beyond on every engagement; it means delivering what you committed to, consistently and well. Good work earns the right to the next conversation. But excellent service on its own has a ceiling: it reliably produces a good reputation, but does not, by itself, produce growth.

Trusted relationships are the second foundation, and in technical services they are gold. Clients hand you problems they cannot fully see, and trust you with decisions that carry real consequences for them. That trust is earned slowly over time. But trust is personal and reactive; it does not automatically reach the next client, the next sector, or the next opportunity.

Visibility is the third foundation. Before anyone can work with you, they have to know you exist: being known, by the right people, for the right things. Like service and trust, it builds naturally over time. A firm that delivers well and earns real relationships builds a reputation, and word travels without anything deliberate being done about it. The difference is pace. Being in the right conversations early, sharing thinking and staying present all speed up what would otherwise happen slowly by itself.

In my experience, the order matters because the direction of failure is asymmetric. A firm with excellent service but limited visibility has a fighting chance. Growth will be slower, dependent on referrals and a few senior relationships, but there is a good foundation to grow from. A firm with high visibility but poor service is in a different, worse position. No amount of business development recovers that. The only path out is fixing the work, which means BD effort is wasted until that is done.

Existing clients are the easiest growth and the most neglected

Something I have observed consistently across my career is that it is significantly easier to grow the work done with an existing client than to find and win a new one. The three foundations help explain why. When you have delivered well, trust is already earned. When you have stayed present and engaged, you are known. What remains is understanding your client's world well enough to find more ways of supporting them, and looking for those opportunities deliberately rather than waiting for them to surface.

New clients still matter, particularly when expanding into new sectors or geographies. But it is worth asking how much effort goes toward cultivating what you already have versus finding what you do not yet.

As my thinking on this developed, I started reading more widely to check whether what I observe in practice is grounded in something beyond my own experience. The answer is yes. David Maister, in Managing the Professional Service Firm, described the business development effort of most professional firms as systematically inverted: the activities with the highest return, serving existing clients exceptionally well and actively nurturing relationships to surface needs that have not yet been articulated, typically receive the least deliberate investment. The effort goes instead toward pursuing new clients and building general market awareness. Both feel more like business development. Neither produces as much of it as looking after what you already have.

He also put a sharper edge on why trust alone does not compound. The people closest to the client (project managers, account managers, senior project staff) carry two responsibilities. One is looking after the client during the work. The other is growing the relationship: noticing adjacent problems, creating conditions for follow-on work, keeping the relationship alive when delivery goes quiet. Most firms are strong at the first. The second usually gets left to chance. No one has made it a deliberate practice with a clear owner.

So this is the ground a business development effort stands on: a clear enough strategy to give it direction, and three foundations, service, trust and visibility, that have to be tended together. The question then is what approach or system actually does that for a firm that wins work through trust and expertise rather than volume or compliance, and whether anything off the shelf already does the job. That is what the next piece takes on.
