The operating model that carried most professional services firms through the last decade is no longer fit for the one ahead. Complexity has compounded across every dimension. Regulatory obligations have multiplied. Client expectations have been recalibrated. The firms that respond by doing more of the same are making their situation structurally worse. The firms that are pulling ahead are redesigning the underlying model, not patching the existing one.
What follows are five design principles that our work with professional services firms has shown to be the defining characteristics of resilient operating models. They are not a sequential methodology — they are a set of interlocking properties that, taken together, determine whether a firm can sustain performance under pressure.
- Regulatory complexity and compliance overhead
- Compressed fee structures and margin erosion
- Technology proliferation without integration
- Rising client expectations for speed and transparency
- Talent retention and knowledge continuity
- Governance that moves at operational speed
- Delivery structures that scale without proportional cost
- Retained context as a competitive asset
- Flexibility without fragility
- Measurable client outcomes, not just activity
Resilience is not built by preparing for specific disruptions. It is built by designing a model that performs well under conditions you have not yet anticipated.
— Actus Verto, Operating Model PracticeComplexity accumulates naturally in organisations. A process that was designed to handle one situation gets extended to cover adjacent ones. A technology tool that solved a point problem acquires integrations, dependencies, and workarounds. A governance layer that was added for good reason becomes a permanent feature long after the reason has passed.
The first design principle of resilient operating models is a deliberate, recurring commitment to simplification. Not simplification as cost-cutting — that is a different exercise with different outcomes. Simplification as design: asking, with genuine rigour, whether every structural element of how the firm operates is earning its place. Whether the process step is adding value or adding friction.
Firms that practice this well schedule it. They build formal simplification reviews into their operating calendar — not as a crisis response when things go wrong, but as a regular discipline. They treat complexity as a cost, measure it, and hold people accountable for it in the same way they hold them accountable for financial performance.
Firms that conduct annual operating model audits — mapping process steps, technology dependencies, and governance touchpoints — consistently identify 20–35% of activity as low-value overhead. The challenge is not identifying it; it is creating the organisational will to remove it.
Flexibility and structure are often positioned as opposites. Firms that want to be agile are told to remove structure; firms that want to be consistent are told to add it. This is a false choice, and acting on it in either direction produces the same outcome: a model that cannot do both things simultaneously.
The operating models that perform best under changing conditions are those that are structured precisely where structure adds value — in how work is defined, how quality is assessed, how knowledge is retained — and flexible everywhere else.
In practice, this principle manifests in the move toward distinct work types with distinct delivery models. A managed service for stable, recurring operational requirements. Structured project packets for defined change initiatives. A clear support function, separated from both, for business-as-usual queries and incidents.
The single most common structural failure we observe is change delivery and operational support competing for the same resource pool. When an urgent support request arrives, it displaces the change pipeline. Over time, the backlog grows, confidence erodes, and the firm is trapped in a permanent state of reactive delivery.
Governance is the connective tissue of an operating model. Done well, it provides the oversight, accountability, and decision-making clarity that lets everything else function at pace. Done poorly — or done at the wrong granularity — it becomes the primary impediment to the firm's ability to act.
Most professional services firms have governance frameworks that were designed for a different operational tempo. Approval cycles built for capital investment decisions are applied unchanged to low-risk software configuration changes. The result is delay, demoralisation, and a gradual erosion of the firm's capacity to respond to anything quickly.
Redesigned operating models distinguish sharply between strategic governance — which should be thorough, deliberative, and appropriately slow — and operational governance, which must be fast, delegated, and calibrated to the actual risk of the decision being made.
Firms that implement tiered decision frameworks — categorising changes by risk level and routing each to the appropriate approval authority — report a 60–70% reduction in elapsed time from decision request to authorisation, with no increase in error rates or governance failures.
Every professional services firm runs on knowledge. The knowledge of its people — their understanding of the firm's processes, systems, client relationships, and institutional history — is not incidental to the firm's value; it is the firm's value. And yet most operating models treat this knowledge as an attribute of individuals rather than as an organisational asset.
The consequences of this are felt most acutely when experienced people leave and when new people join. In both cases, the transfer of contextual knowledge is inefficient, incomplete, and largely unmanaged. Productivity dips. Quality suffers.
Resilient operating models treat knowledge retention as a structural design challenge. They invest in documentation that captures genuine operational knowledge. They structure their partnerships to build and retain contextual knowledge on both sides — recognising that a partner who understands the firm's environment deeply is a fundamentally different asset from one who does not.
The firms that manage knowledge as infrastructure are the ones where new resource deployments — internal or external — reach full effectiveness in weeks rather than months. The investment in knowledge transfer is visible; the cost of not making it is invisible until something goes wrong.
Every operating model will experience disruption. The question is not whether it will happen — it is whether the model is designed to absorb it without cascading failure. Fragile delivery models are those where a single point of dependency can bring the whole system to a halt when it is unavailable or underperforms.
In the context of change delivery specifically, resilience means structuring programmes into discrete, independently deliverable units of work — each with its own defined scope, acceptance criteria, and dependencies mapped. When a unit is disrupted, the others continue.
This principle also addresses quality. Quality failures are not just a quality problem — they are a resilience problem. They consume capacity, erode trust, and compress the margin for managing other disruptions. Investing in quality upstream is an investment in delivery resilience as much as in client satisfaction.
Firms that define acceptance criteria before development begins rather than after reduce rework cycles by an average of 45%. The time spent in upfront definition is recovered many times over in reduced retesting and remediation downstream.
The Diagnostic: Is Your Operating Model Resilient?
The five principles above are assessable. A firm that honestly examines its operating model against each one will quickly identify where the structural vulnerabilities lie.
Operating Model Resilience Diagnostic
Select all that apply to your firmWhere to Begin
For most firms, the honest answer to the diagnostic above will surface two or three principles where the gaps are acute. The temptation is to address all of them simultaneously. We would counsel against it — spreading effort too thinly produces incremental progress everywhere and meaningful progress nowhere.
The more productive approach is to identify the single principle where the gap is widest and the consequences most visible in operational performance — and to begin there, with the ambition of demonstrating a meaningful change within a defined timeframe. Done iteratively, it produces a fundamentally different operating model within two to three years.
Start with an honest audit
Map your current operating model against the five principles. Not where you intend to be — where you actually are. The gap between intention and reality is almost always larger than expected.
Pick the highest-leverage intervention
Identify the structural failure pattern causing the most visible operational pain. A structural problem requires a structural response — more resource applied to a fragile model will not make it resilient.
