    The Autonomy Index

    Six levels of enterprise AI maturity, from automation to autonomous organisations.

    The Autonomy Index is a six-level model for assessing how far an organisation has moved from automating tasks to running processes autonomously. Each level is defined by what the system decides, what it executes, and where humans remain in control. Most European companies today sit between Level 1 and Level 2.

    The six levels

    The six levels in detail

    0

    Data-Driven Automation

    Rule-based automation and predictive analytics. Systems execute instructions written by humans and surface insights humans interpret.

    What the system does

    • Executes scripted sequences across applications (RPA)
    • Applies machine learning models to forecast or classify
    • Produces dashboards and reports

    How to recognise it

    • Automations break when an interface changes
    • Analytics exist but decisions are still made in meetings
    • Every exception returns to a person

    Where it stops

    Automation is brittle because it encodes steps, not intent. Anything outside the script becomes manual work.

    1

    Conversational Copilots

    Natural-language assistants embedded in enterprise workflows. They draft, summarise and answer; humans decide and execute.

    What the system does

    • Drafts documents, emails and code
    • Summarises meetings, contracts and reports
    • Answers questions about internal documents

    How to recognise it

    • Adoption is measured in seats and usage, not in process outcomes
    • Value varies enormously between individuals
    • No business metric has moved as a result

    Where it stops

    Productivity gains are individual, not organisational. The process runs exactly as it did before.

    2

    Cognitive Reasoners

    Generative systems that draft decisions and explain their reasoning. Humans still execute every action.

    What the system does

    • Analyses a case and proposes a decision with justification
    • Compares options against criteria
    • Flags anomalies and inconsistencies

    How to recognise it

    • The AI produces a recommendation a person copies into another system
    • Reasoning is visible but not connected to systems of record
    • Quality is evaluated by reading, not by measuring

    Where it stops

    The last mile is still manual. The system thinks but does not act, so throughput is capped by human transcription.

    3

    Autonomous Agents

    Systems that plan and execute multi-step processes through APIs and tools, inside the company's own systems, under defined policies.

    What the system does

    • Completes a business process end to end
    • Writes to systems of record
    • Escalates exceptions to a human by policy
    • Produces an audit trail of every decision

    How to recognise it

    • A process has a state: running, awaiting approval, escalated
    • Permissions and thresholds are configured, not improvised
    • The process owner can answer why an action was taken

    Where it stops

    Each agent operates within its own domain. Work crossing business units still requires a human to coordinate.

    4

    Swarm Intelligence

    Cooperating agents that self-orchestrate across domains, hand off work and reach consensus without human coordination.

    What the system does

    • Routes work between agents across functions
    • Resolves conflicting objectives against shared policy
    • Reallocates capacity dynamically

    How to recognise it

    • Cross-functional processes complete without a coordinator
    • Governance operates at the level of the system, not the single agent

    Where it stops

    Governance complexity grows faster than capability. Very few production deployments exist today, and accountability models are still immature.

    5

    Autonomous Organisations

    Enterprises where the operating structure is largely executed by AI, with virtual org charts and a synthetic workforce. Humans set objectives, policy and boundaries.

    What the system does

    • Runs entire functions without a human operating layer
    • Adjusts strategy execution against outcomes

    How to recognise it

    • No verified production example exists today.

    Where it stops

    Level 5 is not achievable with current technology, and the legal and accountability frameworks it would require do not yet exist. It is a direction of travel, not a roadmap item.

    Where is the market today?

    LevelAdoption todayWhat it takes to get there
    0WidespreadProcess documentation and system access
    1WidespreadLicences and change management
    2GrowingDomain context and evaluation discipline
    3Early productionIntegrations, policy model, audit trail
    4ExperimentalCross-domain governance, consensus model
    5TheoreticalLegal and accountability frameworks that do not yet exist

    The gap between Level 2 and Level 3 is where most AI programmes stall. It is not a model problem — it is an integration, permission and governance problem.

    How do you assess your level?

    Ten closed questions. The result is shown immediately, in full, without an email address.

    Question 1 / 10

    Can AI systems in your organisation write to systems of record, or only produce output a person transfers manually?

    All ten questions

    Answer options: Yes · Partially · No

    1. Can AI systems in your organisation write to systems of record, or only produce output a person transfers manually?
    2. Is there at least one business process that completes end to end without human execution?
    3. Are agent permissions defined as policy, or configured case by case?
    4. Can you reconstruct why an automated decision was taken, six months later?
    5. Do exceptions escalate automatically to a named owner?
    6. Is AI performance measured by a business metric, or by usage?
    7. Do automated processes cross business unit boundaries?
    8. Is there a defined control regime per process — human in the loop or human over the loop?
    9. Are model and data residency constraints enforced at runtime, or checked in review?
    10. Would your current AI deployment survive an external audit?
