How UK CEOs Must Redesign Their Operating Model for AI in 2026

AI operating model redesign is now the UK CEO’s most consequential strategic decision: 72% of CEOs report that AI investments are not yet delivering expected productivity improvements — and the primary barrier is not technology, it is an organisational structure built for human workers that has not been redesigned for autonomous AI agents.

Why Is Operating Model Redesign Now a CEO Responsibility, Not an IT Project?

For the first three years of the enterprise AI cycle, the dominant narrative was one of technology deployment: select the platform, run the pilots, scale what works. That narrative has reached its limits. According to the IBM 2026 CEO Study, which surveyed more than 1,500 global chief executives, 72% report that AI investments are not yet delivering the productivity improvements expected at board level. The primary barrier cited is not technology — it is organisational design.

The operating model — the way decisions are made, roles are defined, processes are structured, and value is created — was built for human workers operating within hierarchical command structures. Agentic AI systems, which can now autonomously execute multi-step workflows across enterprise software, do not fit neatly into this structure. They require new definitions of authority, new accountability frameworks, and new management practices that most UK organisations have not yet developed.

Under the UK Corporate Governance Code, the CEO is directly accountable for designing and maintaining an effective organisational structure. Boards are asking their CEOs not simply whether AI is being adopted, but whether the organisation’s operating model has been redesigned to extract sustainable value from it. According to EY’s May 2026 UK CEO Survey, 87% of UK CEOs are pursuing M&A activity to accelerate AI capability — but the organisations acquiring these capabilities have yet to restructure how work, authority, and value creation are distributed around them.

Executive Action:

• Commission a current-state audit of your operating model: where are decisions made, which roles are primarily information-processing, and which processes are already end-to-end automated?
• Brief your board on the gap between your AI investment thesis and your current operating model — the two must be aligned for productivity gains to materialise.
• Define three operating model changes to be implemented in 2026, with named executive ownership and measurable outcome targets.

What Does a Human-Plus-Agent Operating Model Look Like in Practice?

The conceptual shift required is from human roles augmented by AI tools to operating models designed around the combination of human judgment and AI execution. BCG’s AI Transformation research (2026) identifies four structural changes that characterise organisations successfully making this transition.

Role redesign around orchestration: Roles that previously involved routine information processing — financial reporting, customer query triage, compliance monitoring, procurement approvals below threshold — are being redesigned around oversight, quality assurance, and exception handling. The human role becomes orchestrator: setting objectives, reviewing agent outputs, handling exceptions, and continuously improving the agent’s performance parameters.

Decision authority at the edges: Centralised decision-making slows down in an AI-native operating model because the volume of decisions that AI systems can make in real time exceeds the bandwidth of centralised approval processes. The most effective organisations are pushing decision authority closer to customer-facing roles while reserving strategic and high-stakes decisions for executive layers.

Accountable AI ownership: Each AI-enabled process needs a named human owner who is accountable for the outcomes produced, not just the deployment decisions. This is both a governance requirement — under SMCR in financial services, under the UK Corporate Governance Code more broadly — and an operational necessity: someone must be answerable when the agent produces a wrong output.

Metrics redesign: Most organisational KPIs were designed to measure human output. In a human-plus-agent model, the relevant metrics include agent task completion rates, human override frequencies, error rates by process type, and time-to-exception-resolution. CEOs who continue to measure AI performance against legacy productivity metrics will misread the transition entirely.

Executive Action:

• Identify the five highest-volume routine decision processes in your organisation and assess whether each can be redesigned around AI execution with human oversight.
• Redesign three role profiles in the next quarter to reflect orchestration responsibilities — use these as pilots for broader operating model change.
• Update your strategic plan KPIs to include AI-specific performance metrics alongside legacy productivity measures.

How Should the CEO Manage the Workforce Transition?

The operating model redesign that AI demands is also a workforce transformation. According to BCG’s AI Transformation research (2026), organisations that deploy AI without redesigning roles or retraining people consistently underperform those that treat AI adoption as a people-led change programme alongside the technology deployment.

For UK CEOs, the regulatory and legal context adds complexity. The Employment Rights Act 2025, which took effect in stages through 2026, strengthens collective consultation rights and increases the minimum protective award for failure to consult. Any operating model redesign that involves role changes or redeployment requires careful TUPE, redundancy, and collective consultation analysis — and CEOs who skip this step face material legal exposure as well as cultural damage.

EY’s May 2026 UK CEO Survey found that 69% of UK CEOs pursuing M&A activity to acquire AI capability were specifically targeting companies with existing AI-trained workforces — a recognition that the human capability gap is as significant as the technology gap. CEOs who treat operating model redesign as primarily a cost reduction exercise — using AI deployment to reduce headcount without investing in capability building — are creating significant legal and cultural risk simultaneously.

The most effective approach is parallel-track: technology deployment and workforce transition proceed simultaneously, with the CEO personally visible in communicating the rationale, timeline, and support available to affected employees. This is not an HR communication exercise — it is a strategic leadership requirement.

Our Strategy and Transformation briefings provide detailed operating model frameworks for the AI transition. Access our Executive Assessment tools to benchmark your organisation’s AI operating model maturity against sector peers.

Executive Action:

• Appoint a cross-functional AI Transformation team with C-suite membership and CEO sponsorship — technology, operations, HR, finance, and legal must all be represented.
• Develop a workforce transition plan aligned to your operating model redesign timeline, with upskilling investment quantified and board-approved.
• Communicate the operating model vision directly from the CEO — not via HR or IT — to signal that this is a strategic programme, not a technology project or a cost exercise.

How Should Boards Measure CEO Performance on This Agenda?

The board’s role in AI operating model transformation is to set expectations, provide accountability, and ensure the CEO has the mandate and resources to make structural changes that cut across functional boundaries. Under the UK Corporate Governance Code, the board is responsible for ensuring that the organisation has the leadership, capabilities, and culture necessary to achieve its strategic objectives — and in 2026, that explicitly includes AI readiness.

Boards should resist the temptation to measure CEO progress on AI transformation solely through financial metrics — cost savings, headcount ratios, or technology spend as a percentage of revenue. These measures are lagging indicators that will not reveal whether the operating model is actually changing until it is too late to course-correct. Instead, boards should require the CEO to report quarterly against a small set of leading indicators: the number of processes redesigned around AI execution, the percentage of roles with documented orchestration responsibilities, and the organisation’s AI incident response capability.

The Remuneration Committee should also consider whether AI operating model transformation is appropriately weighted in the CEO’s long-term incentive plan. Organisations that anchor executive incentives exclusively to near-term financial performance will find it difficult to sustain the investment in operating model change that AI transformation requires.
