Hiring More People Won't Fix GRC & TIC Delivery

When the pipeline fills and delivery timelines start to stretch, the conversation in most GRC and TIC firms moves quickly to headcount. Bring in more auditors, more inspectors, more qualified reviewers. The logic feels sound, more capacity means more throughput.

The problem is that capacity and headcount are not the same thing in an expert-led firm, and the gap between them is exactly where growth pressure builds. In earlier pieces in this series we explored why growth breaks in GRC and TIC firms and why rising revenue is not translating into better margins. The hiring question is where both of those threads weave together.

The Supply of Qualified GRC and TIC Professionals Is Decreasing

Let’s start with the supply side, because the hiring answer is harder to find than most firms expect.

According to the FRC's 2025 Key Facts and Trends in the Accountancy Profession, the number of UK registered statutory audit firms fell from 5,007 in 2020 to 3,760 in 2024, a 24.9 per cent decline. ICAEW audit qualifications dropped from 1,900 to 1,800 over the same period.

The sector needs approximately 11,600 new specialists a year and is nowhere near producing them. Nearly half of audit firms (49 per cent) already offshore work simply to manage capacity constraints.

This is a structural constraint rather than a near-term pipeline problem. The qualified professional pool available to GRC and TIC firms is shrinking, and the regulatory expansion driving demand is moving faster than the profession is producing people to meet it.

For COOs planning a hiring round, that supply picture is worth understanding before the round begins. Competition for qualified reviewers and inspectors will intensify, time-to-hire will extend, and the window between opening a role and having a net-positive contributor is longer than most operational plans account for.

In a Fragmented GRC or TIC Model, Every New Hire Adds Coordination Cost Before It Adds Capacity

Even in firms where hiring is viable, the capacity gain from a new professional is rarely what the headcount arithmetic suggests.

In a fragmented operating model, adding a delivery professional generates additional demand on every function surrounding them. If your firm uses one coordinator per eight auditors as a planning ratio, hiring eight auditors means hiring a coordinator too.

As people find their feet, this triggers additional

• Scheduling complexity
• QA volume
• Reporting lines
• Exception handling

None of that overhead sits in a single budget line. The additional scheduling time is inside operations, the additional QA work sits inside quality and the additional management attention is absorbed by the leadership team without appearing on the management pack.

It means that while each individual cost looks manageable, in reality, the overhead of absorbing new hires into a complex operating model is substantial.

Hiring into a fragmented model creates proportional complexity.

The firms that feel this most acutely are typically those that have grown through acquisition. When each entity runs its own scheduling tools, report templates and QA processes, every new professional joins a system that requires more coordination than a designed operating model would.

The work of getting them calibrated to local practices and integrated into the delivery flow adds overhead before they contribute a single piece of certified output.

A New GRC or TIC Hire Typically Takes 12 to 18 Months to Become Net-Positive

The timeline issue reinforces the capacity argument. A new hire in a complex GRC or TIC operating model typically takes 12 to 18 months to become net-positive for the operation.

In that window, they are consuming scheduling resources, QA reviewer time, senior oversight and onboarding coordination, which generates work for others while building toward independent contribution.

In our experience, you can’t put this down to a failure of the recruitment process. Procedures have been followed as necessary. So what’s going wrong?

We argue that it’s a feature of operating models that have grown organically, where the knowledge, processes and relationships needed to deliver well are embedded in people rather than in the system. When those conditions exist, each new hire has to reconstruct institutional knowledge the system has never documented.

For COOs approving hiring rounds, the question worth sitting with is:

If the answer to delivery pressure is headcount, and each new head takes 12 to 18 months to contribute net capacity, what does the delivery problem look like during that ramp?

And consequently, what happens to the operating model's complexity as each new layer arrives?

Where GRC and TIC Firms Are Finding Capacity Without Hiring

The firms absorbing demand growth without breaking are recovering capacity from inside the operating model they already have.

When qualified auditors, inspectors and consultants spend an estimated 25-40% of their working week on report formatting, scheduling administration, QA rework and data re-entry across disconnected systems, the available capacity in a firm is already materially larger than its utilisation figures suggest.

The first simplification cycle in a firm where the operating model has evolved organically typically recovers 15 to 20 per cent of expert capacity previously absorbed by non-core activity. It’s the equivalent of adding one qualified professional for every five or six already on the team, with no hire required and no 12-month ramp.

The firms that see this have stopped treating headcount as the primary lever for delivery pressure. They start with operational reality:

1. Measure where qualified time actually goes,
2. Identify the highest-friction constraints, and
3. Redesign around them.

For many firms, the capacity is already there. The task is to stop the operating model consuming it.

That is the premise behind our Simplify4Scale methodology: start with operational reality, address the highest-friction constraints first, and build the internal capability to sustain the improvement.

Our whitepaper, Scale Without Hiring: A COO's Guide to Unlocking Growth in GRC and TIC Through Operational Design, sets out the diagnostic approach in full, including how to measure where qualified time is going and where the redesign opportunities are highest.
