Adapt or Drift: Resilience Engineering When AI Moves the Operating Point
Andrew Hatch
The Blocker Lemming represents deliberate safety intervention: pause or redirect work to preserve margin.
Session: Adapt or Drift: Resilience Engineering When AI Moves the Operating Point.
We have more capability than ever before
But less certainty we’re in control
Decades of research on sociotechnical systems and complexity still explain these risks.
Will our ability to notice, understand and correct keep pace?
AI is changing what we can do and how fast we can do it. Rasmussen’s model still helps us understand the pressures. The question is whether our ability to notice, understand and correct can keep pace.
AI can radically change how work gets done while still fitting familiar patterns of adaptation under pressure. But it can also influence what people accept as evidence and how intent becomes action. That changes the mechanisms we use to understand and control the system.
The framework can remain useful while our assumptions need rechecking. Decades of research give us a lens. They don’t guarantee that familiar review processes or feedback loops will remain adequate.
Rasmussen supplies the boundary and control framework. Applying it to AI’s tempo, verification demand and feedback delay is this talk’s synthesis. Evaluate whether people, tools and workflow retain the capacity to intervene and recover. AI can also improve assurance.

Resilience Engineering
Build and sustain adaptive capacity in socio-technical systems, both technical and non-technical, ensuring they can absorb and recover safely from incidents, anomalies and changing pressures.
Build the ability to adapt before it is needed
The opening definition is this talk’s synthesis, not a quotation. Resilience Engineering is the study and deliberate support of the capacities that help socio-technical systems continue to perform as conditions change. Sustaining that ability means maintaining expertise, coordination, time, resources and authority to act, and renewing them as the system evolves. Adaptive capacity is not simply spare infrastructure capacity.
Incidents and anomalies make adaptation visible, but it also occurs in everyday work. Keeping functioning can involve changing plans, priorities or ways of working. This does not promise immunity from disruption or unlimited capacity to absorb any event. Prepare for situations that exceed what was anticipated, and learn how people already prevent difficulties from becoming worse.
John Allspaw’s March 6, 2019 presentation abstract also places investment in adaptive capacity at the centre of the field. It remains a background source for the definition: Amplifying Sources of Resilience.

Systems Thinking
Introduce Jens Rasmussen and the 1997 model. The next slide maps the wider research landscape around Figure 3, and the slide after that locates people and technology within Rasmussen’s social control hierarchy before the boundary model is translated into plain language.
- The original model comes from Risk Management in a Dynamic Society (1997).
- Examples of safety-critical domains include radiological safety, maritime safety and healthcare.
- Socio-technical systems are hierarchical and multidisciplinary.
- Systems thinking connects these levels and disciplines.
Paper: Rasmussen, Risk Management in a Dynamic Society (1997).
The research behind the model
The 31-page paper connects decades of studies across engineering and the human sciences.
Risk analysis Different hazards require different strategies
Defence in depth Redundant layers can erode without visible failure
Human performance under pressure Studies move from error rates to work in context
Feedback control Controllers need current state, authority, and competence
Naturalistic decisions Local adaptations interact across the system
This is a synthesis paper rather than a single empirical validation of the model.
- Rasmussen distinguishes empirical, evolutionary, and analytical risk strategies.
- Defence in depth matters, but redundant protections can degrade quietly because a local violation may have no immediate visible effect.
- The paper reviews human reliability, operator modelling, field evidence, and organisational research. Its direction of travel is away from isolated error counts and toward behaviour in a real work context shaped by workload, time, cost, and competing goals.
- Risk management becomes a feedback-control problem spanning the whole socio-technical hierarchy.
- Decisions are embedded in continuous work. Locally sensible adaptations can interact across controllers and create system-level risk.
The next slide makes the paper’s system-wide control hierarchy concrete, and the following slide simplifies the geometry without discarding these mechanisms.

Where does control live?
Social control hierarchy Rasmussen’s structural hierarchy
The social control hierarchy surrounds the people and technology doing the work. Research disciplines and environmental stressors cross its levels.
Control is distributed rather than owned by any single actor, and information must travel upward while decisions and constraints travel downward. Each layer adapts on a different timescale.
Goals, evidence and authority
The control structure is the distributed network of decision makers, goals, constraints, information, competence and authority around the work. Observations and outcomes inform decisions, and decisions and constraints change the work. Feedback must reach actors with the resources and authority to respond.
When AI enters these channels, re-examine problem framing, attention, verification, skill retention under pressure, communicated intent and feedback fidelity across the hierarchy. Task-level studies do not establish the accumulated effects on a whole socio-technical system.

Putting it together
👩🏿
👨🏼
🧑🏽
🧕🏻
The hierarchy on the previous slide surrounds the people and interactions in this complex system. People and technology operate within economic, workload and performance constraints. The dotted error margin marks a buffer inside the performance boundary.
The following slide explains the boundaries and the margin in detail.
Adaptation with LLM tools
Tools change the conditions in which people work, and repeated adaptations change workflows, expectations and later decisions. Rasmussen remains a framework for examining these effects. Measures of human performance, learning, coordination and control need revalidation in LLM-mediated work. This does not make earlier human-factors research obsolete.

💸 Boundary to economic failure
😢 Boundary to unacceptable workload
Boundary of functionally acceptable performance 💥
Error Margin
Plain-language script
“The economic boundary marks where we can no longer pay the bills. The workload boundary marks where people cannot keep going. The performance boundary marks where the system can no longer do its job acceptably or safely. We cannot see that line exactly, so the dotted line gives us a margin for error.
This dot is not a person. It is the whole system — people, software, and rules — working right now. The dim dot marks the starting reference position, not a second current operating state. The shaded area is the playing surface, with the error margin shown in orange.
Economic and workload limits can change as financial and human capacity change. Inward shifts reduce the playing surface; outward shifts expand it.
Pressure for efficiency and less effort can draw normal adaptations, and the whole system's operating state, toward the performance boundary.
The charts stand for pressure to reduce cost, which a downturn can intensify. The hands stand for ways people reduce effort under workload; the Blocker Lemmings show safety action near the error margin: pause or redirect work to preserve margin. Rasmussen describes actors adapting within the work-space, encountering an effort gradient while management supplies a cost gradient. The charts and hands are scattered through that space to illustrate local adaptations, not measured locations of individual decisions in Figure 3.
The economic-side arrow shows the gradient toward cost efficiency; the workload-side arrow shows the gradient toward least effort. Both point toward the acceptable-performance side. Figure 3 and its adjacent discussion support these directions of migration. The arrow endpoints are illustrative rather than measured positions or fixed targets.
Everyone makes sensible choices. The business asks for cheaper and faster. People make work easier. Together, those pressures can move the dot toward the performance edge.
There is no magic safe spot in the middle. The lines do not push the dot back. Any line can move as demand, staffing, technology, or AI changes.
That is Rasmussen's warning: failure does not require one stupid decision. Normal adaptations can slowly move the system toward an edge nobody can see exactly.”
Core point: one current operating state moves within economic, workload, and acceptable-performance constraints; pressures move it, while sensing and control preserve margin and recoverability.

Economic Boundary
External conditions change what the business can sustain.
More room to operate
- 📈Stronger demand and better pricing power
- 💰Fresh funding or cheaper financing
- 🏭Lower energy, supplier or infrastructure costs
Less room to operate
- 📉Market slowdown, churn or price competition
- 🏦Costlier credit or funding that dries up
- 💱Higher supplier costs or currency shocks
Greater financial capacity expands room to operate, tighter budgets increase pressure to reduce costs.
Activity, capacity and control
More consumption or commitments can move the operating state toward economic failure when costs outpace value and supporting financial capacity. Sustainable savings can expand viable operating space; reduced revenue, funding or runway can contract it. Forecasts provide feedback, and budgets or quotas are management targets and decision thresholds. Revised targets do not by themselves change the actual viability constraint. Rasmussen draws the perceived boundary and error margin only on the performance side.
Economic Boundary Actions
Signals become decisions that push toward cost efficiency.
| Leading signal / metric | Possible management action |
|---|---|
💸Forecast cash burn increases |
✂️Reduce scope, defer investment, reprioritize commitments |
🧾Cost per verified outcome increases |
🤝Renegotiate suppliers, rightsize resources, remove low-value work |
💤Idle capacity or unused licences |
🧹Consolidate platforms, retire unused capacity |
🗜️Projected margin decreases |
Freeze hiring, reduce staffing or maintenance |
Cutting waste can reduce costs, but cutting expertise or maintenance can leave less room to operate safely.
Account for transferred work
Chapter 5 §5.2.4 (printed p. 81; supplied PDF p. 89) asks who receives a saving, who absorbs the work, and when it becomes visible. Track authoring savings beside reviewer, maintainer and on-call costs. Section 5.5.2 (printed p. 85; PDF p. 93) extends evaluation to future adaptability, coupling, congestion and conflict. A local saving is not sufficient evidence of a net workflow saving.
Financial feedback must reach people with authority, competence and resources to change commitments. They must communicate effects on review demand, maintenance and recovery across levels. Savings preserve other margins when low-value work is removed. If output stays fixed while expertise or review are cut, the resulting adaptations can transfer pressure into workload and acceptable performance.

Workload Boundary
The sustainable capacity to do and understand the work can change.
More room to operate
- 🎓More trained people and relevant expertise
- 🛠️Better tools and reliable toil reduction
- 🕒Protected focus, recovery time and knowledge sharing
Less room to operate
Attrition, layoffs or unavailable specialists- 🥵Fatigue, burnout and constant interruptions
- 🔥Fragile tooling and lost operational knowledge
Less capacity moves the boundary inward, more work can push the operating point toward it.
Focused verification capacity
Effective capacity means relevant expertise, focused time and enough context for this work, not merely assigned headcount. A reviewer can be allocated to many tasks yet lack usable time to assess this change. Protect contextual knowledge and recovery; changing demand or removing expert capacity can also change the verification effort required per item.
- Rasmussen (1997), Figures 1 and 3; control, adaptation and information
Workload Boundary Actions
People adapt toward least effort when demand strains capacity.
| Early signal / metric | Possible adaptation |
|---|---|
⏳Queue age and work in progress |
🛠️Automate repeatable toil, improve tooling, limit incoming work |
🤝Interruptions and handoffs Focus time |
🗂️Batch tasks, standardize paths, simplify tools and coordination |
🥵Overtime and fatigue Recovery time |
🛌Reduce scope, protect rest, share on-call load or rush and bypass checks |
🔁Review findings and rework |
🧪Improve tests and shared understanding or accept output without examining it |
Reducing toil can preserve control, but skipping checks saves effort now and creates work later.
Match admission to assurance
Count admitted work, focused verification effort per change and effective capacity. The review-load ratio in TALK.md is this talk’s illustrative capacity heuristic, not a measure established by Chapter 5. Demand rising relative to capacity can increase backlog and delay. Defects additionally depend on adaptations such as reduced review or testing; queue growth alone does not demonstrate a defect increase.
Change scope, timing or admitted work, and accept latency when necessary. Preserve source evidence and give reviewers time and practical authority to reject, pause or reverse action. Chapter 5 §5.1 (printed pp. 78–80; PDF pp. 86–88) illustrates responsibility without resources through a scenario, not a measured universal outcome. AI can strengthen tests, diagnosis and verification where tools actually help.

Boundary of
Acceptable Performance
Crossing the functional limit means unacceptable outcomes.
Failure in the service
- 🚨Outages and cascading system failures
- 🔓Lost, corrupted or exposed customer data
- ⏳Recovery that cannot restore service in time
Consequences
- 🚧Customer operations disrupted, safety put at risk
- 💔Trust and reputation damaged
- ⚖️Contractual losses or regulatory consequences
Can people, tools and workflows anticipate and adapt to failure, ensuring system capacity remains resilient to performance degradation and recovers?
Joint performance over the lifecycle
Evaluate people, tools and workflow together across good, mediocre and poor AI output. A model benchmark alone cannot establish operational joint performance. Chapter 5 §5.5.3 (printed pp. 85–86; PDF pp. 93–94) calls for evaluation situated in the actual work and repeated through the lifecycle.
Compare verified outcomes, revision and checking effort with a relevant baseline. Include a plausible consequential mistake in a controlled exercise: can people access the evidence, detect it and correct it before enactment? Measure outcome quality, verification effort, consequential-error detection, response time and successful recovery. Re-evaluate when models, workflow, staffing or dependencies materially change. These are proposed engineering measures rather than a universal score; operational signals remain imperfect proxies for the true functional limit.
Morey, Rayo and Woods (2025) studied predictive clinical AI in simulated patient cases with 450 nursing students and 12 licensed nurses. Recommendation correctness improved or degraded joint performance. Added explanations did not significantly change those effects in this experiment. It motivates the evaluation design; it is not an LLM software-risk estimate or evidence that explanations never help.

The Error Margin
Notice, act and recover before the functional limit is crossed.
| Signal / concern | Protective actions |
|---|---|
🕳️Blind spots or stale telemetry |
🔎Improve monitoring, check user journeys, connect alerts to an owner who can act |
🪫Saturation or shrinking headroom |
⚙️Improve software efficiency, load-test, add scalable capacity and tested redundancy |
🌊Changes exceed verification capacity |
🚦Limit admission, use canaries and rollback, retain independent review and access controls |
⏳Slow or uncertain recovery |
🛟Exercise failover and restore, update runbooks, practice diagnosis and share expertise |
Sustain adaptive capacity by turning signals into effective action
Notice, intervene and recover
Deliberate interventions pause or redirect work to preserve margin. Someone needs the evidence, authority and capacity to act.
Notice requires usable signals and timely interpretation. Intervention requires evidence, authority, tools and remaining response capacity. Recovery requires contextual knowledge and fallbacks that people can use under pressure. A written rollback procedure does not establish that capability. Awareness and the margin itself exert no automatic restoring force; the objective is sufficient margin, bounded excursions and recoverability, not a preferred geometric center.
Exercise stale observations, scarce time, excess review demand and unavailable supporting services outside production. Assess whether the team can pause, reduce scope and recover. Chapter 5 §§5.3.2–5.3.5 (printed pp. 82–84; PDF pp. 90–92) discusses difficulties recognizing plausible errors; §5.1 illustrates responsibility without resources and decay of alternatives; §§5.4–5.5 (printed pp. 84–86; PDF pp. 92–94) support challenging exercises and continuing assurance.
The AWS 19–20 October 2025 disruption report describes conventional automation and dependencies, with no reported generative AI involvement. Delayed DNS-plan application interacted with changed state and cleanup; subsequent EC2 recovery entered congestive collapse. AWS announced recovery testing and controls on incoming work. The report does not establish that all announced work was complete. Use it as a control-and-recovery mechanism example, not an AI-caused incident or a general verdict on automation.

What happens as AI infiltrates every part of the system?
The operating point represents the whole socio-technical system's current state. The AI artwork is shorthand for AI-mediated work at that same state, not a second operating point, a person or a fourth constraint. The reference ball marks the starting state, not an ideal or inherently safe location.
Ask what changes in cost, effort, evidence and recovery when AI enters the work.
AI in the feedback and action channels
AI is not automatically a new controller. It influences channels used by existing controllers. On the feedback side it can gather and summarize observations, find contradictions and support testing; fluent summaries can also conceal uncertainty. On the action side it can present options, draft decisions and translate intent into output; plausible detail can exceed the communicator’s intended criteria.
AI output changes the operating state when people or automation admit and enact the resulting decisions, not merely when output is generated. The risk is conditional: AI can strengthen testing, diagnosis, challenge and verification. Risk rises when generation and action become easier faster than assurance and correction.
Rasmussen (1997) describes behaviour and work activity migrating toward the boundary. Cook and Rasmussen (2005) explicitly use operating-point terminology. The ball remains shorthand for one current whole-system state.

💸 Boundary to economic failure
😢 Boundary to unacceptable workload
Boundary of functionally acceptable performance 💥
And work function and outputs rely heavily on non-determinism?
The same constraints still apply
Economic failure, unacceptable workload and functionally unacceptable performance remain the three constraints. The error margin is the protected performance-side buffer, not an additional constraint. AI does not create a fourth boundary.
The moving ball represents one current whole-system state. The reference ball marks the starting position, not a second current state or an ideal geometric centre.
The trajectory illustrates how adaptation under pressure can move the operating state toward the performance side. It is not a measured path. Organisational choices and usable feedback shape the actual trajectory, and no geometric centre guarantees safety.
Ask how non-deterministic outputs change what people can understand, verify and rely on. Examine the consequences for economics, workload, expertise and the capacity to intervene and recover.
AI has to be paid for
Cheaper generation can still mean higher total cost.
The bill grows
- 📈47% of surveyed tech leaders reported AI spending over plan. ETR, 2026
- 🪫Uber’s annual AI budget was exhausted by April. CTO interview, 2026
- 🔁More seats, agent loops and adoption add demand.
Money moves
- 🏗️Cut infrastructure refresh to fund AI overruns: 49% of firms reallocating budgets. ETR, 2026
- 🏦Bring in outside capital: Meta’s $27bn Hyperion venture with Blue Owl. 2025
- 🎯Redirect investment toward AI products with stronger expected returns.
Savings here can add work elsewhere. Who covers it and at what cost?
Whole-workflow economics
Include model use, platform commitments, integration, tools and data, evaluation, human verification, rework and recovery in outcome cost. Longer contexts, retries, agent loops and additional workflows can consume unit-cost savings. This is conditional, not a prediction that cheaper AI must increase spending. Evaluate work transferred or deferred to reviewers, maintainers and responders, along with future coupling, congestion and recovery costs.
Preserve capacity by reducing low-value demand, bounding loops, changing scope and routing or caching where verified quality permits. Organizations may also redirect portfolios toward products with stronger expected returns, as the visible example suggests. Keep verification and recovery funded. AI can improve tests and diagnosis as well as generation. If required output stays constant while relevant expertise or review is removed, workload can rise and performance margin can shrink.

Tokenomics Evolution
| Stage | Control intent |
|---|---|
| 🏆Maxxing | Treat token consumption as a score to maximise. |
| 📏Metering | Count token use to track limits and allowances. |
| 🔀Optimization | Route users’ requests to cheaper models to reduce costs. |
How does commercial AI evolve from here, and what are the risks?
Token consumption, dependence and platform power
Tokenmaxxing turns LLM-agent consumption into a public scoreboard. The tokenmaxxing.sh leaderboard ranks token counts and estimated API-equivalent spending. Those estimates are not reconciled bills, and token consumption does not measure useful outcomes, productivity or quality. These are language-model usage tokens, not cryptocurrency. The site was checked on October 27, 2026.
Doctorow’s enshittification model describes two-sided platforms. They first offer users substantial value, then shift value toward business customers such as advertisers and sellers, then squeeze both groups to retain more surplus for the platform. Business customers are distinct from the platform owner. This is a conditional analogy about AI dependence and pricing power, not a claim about every provider or measured model quality.
Cursor’s August 12, 2025 announcement describes a change in metering. Individual Auto usage had been unlimited since June. The announcement said it would count against included monthly usage at token rates from each user’s next renewal after September 15, 2025. Some annual renewals could fall in 2026. This dates the announcement and planned transition, not independently confirmed rollout for every subscriber. This does not establish deliberate lock-in, reduced model quality or rent extraction.
Optimization describes a business routing users’ requests to cheaper models to reduce costs. Microsoft’s model-router documentation describes a Cost mode that favours smaller, cheaper models, with possible quality trade-offs on complex prompts. Routing requires evaluation against the actual workload. Cheaper routing alone does not demonstrate deliberate degradation or Doctorow’s full platform cycle.
The parallel is a risk to examine: when workflows depend on a provider, that provider controls the meter and can change the terms. Token leaderboards can reward consumption while the organization needs useful, verified outcomes. These documented examples do not establish that every AI provider has completed Doctorow’s cycle. Ask about switching costs, portability, alternative suppliers and outcome cost before increased use becomes a commitment that is difficult to unwind.

AI prices have fallen for the same capability. But!!
Stanford AI Index, 2025Lower costs don’t guarantee lower prices.
Cloud-market example: CMA, 2025Cory Doctorow, Enshittification (2025)
Doctorow describes a two-sided platform moving value from users to business customers, then taking more from both groups. Business customers mean advertisers, sellers or other participants, distinct from the platform owner. The headings are a paraphrase. Applying this pattern to AI is a risk to examine, not a prediction that every provider follows it.
Lower costs do not determine who keeps the savings
Stanford’s AI Index article reports that the price of querying models at GPT-3.5-level MMLU performance fell from $20 per million tokens in November 2022 to $0.07 in October 2024. Its 2025 report also describes hardware costs per unit of performance declining by 30% annually. These are historical trends, not guarantees about future token prices or total workflow costs.
The cloud analogy concerns competition and switching. For its UK and EEA market definition, the CMA’s July 2025 cloud decision found concentrated supply, sustained AWS and Microsoft returns above their cost of capital, and barriers to switching. Its April 2024 foundation-model review identified risks from control over critical inputs and routes to customers. These findings support questioning how fully efficiency gains reach customers, rather than asserting an inevitable AI oligopoly.
The October 2026 CMA update records improvements, including removal of transfer fees for switching providers, while identifying remaining barriers. Cloud prices have risen for some services and fallen for others. The precedent is imperfect competition, not a claim that cloud prices never fall.
DeepSeek still supplies MIT-licensed model weights and charges for its hosted API. Open weights do not mean free compute. The evidence does not establish that incumbents will push DeepSeek out. The question is whether competing models remain practically accessible and switching remains viable as the market evolves.
AI and least effort
AI can make “generate, accept, act” the path of least effort.
Proxy the judgment
Pass off plausible AI reasoning as your own judgment.
Quick answers can hide a lack of understanding.
Multiply the streams
Agents generate more proposals, and humans inherit
review, integration and maintenance.
Squeeze recovery
Extra checking and context switching can
raise workload and burnout risk.
Evidence, capacity and understanding
Least effort describes normal adaptation under competing goals and limited attention, not a moral claim about laziness. Plausible ≠ measured. Fluent ≠ intended. Fast generation does not establish fast verification, integration or maintenance. Conflicting AI proposals still require people to reconstruct context and understand fundamentals. The meat-proxy scenario is this talk’s illustration, not a claim that all AI use reduces expertise. Chapter 5 §§5.3.1–5.3.4 (printed pp. 82–83; PDF pp. 90–91) discusses filtering, revision and plausible errors that need expertise to recognize and correct.
Current LLM evidence shows changes in task pace and cognitive effort that differ by task and experience. Lee et al. (CHI 2025) surveyed 319 knowledge workers: critical-thinking effort shifted toward verification, response integration and task stewardship, while higher confidence in AI was associated with less scrutiny. This is self-reported association, not causal proof. Dell’Acqua et al. randomized 758 consultants: work was faster and higher quality within the model’s capability frontier, but correctness was lower outside it. These are task-specific results, not a universal effect or a whole-system risk estimate. Dillon et al. and Brynjolfsson, Li and Raymond provide additional heterogeneous workplace evidence.
Preserve focused attention, contextual knowledge and usable authority to change commitments. Change scope, timing or admitted demand when checking cannot keep pace. AI can improve assurance capacity where joint evidence supports its testing and diagnosis. Demand relative to capacity can increase backlog and delay; defects additionally depend on adaptations that shed assurance. Do not treat generated backlog clearance as verified completion.

This is a discussion of the risk to expertise, not a measured claim that all AI use erodes it.
Doctorow’s reverse-centaur distinction asks who controls the work: whether a person chooses how a machine assists them or is required to serve the machine’s pace and demands.

The people, shrugging, flame and “This is Fine” are a metaphor for uncertain understanding and unaddressed trouble in a complex system. The system remains complex even when the people responsible for it can no longer explain what is happening or how to intervene.
This is an illustration of a risk to expertise and control, not evidence that every use of AI causes expertise loss or failure.

where we think we are
🚨
The buckets represent accumulating verification and repair work. The Lemming represents the expertise and response capacity needed to protect performance. Cheap generation can move checking, maintenance and recovery work elsewhere, consuming attention and capacity even as visible output increases.
The dotted line warns about the remaining buffer. Crossing it begins consuming protected error margin, while the solid line marks the actual functional limit. A warning helps only if people have practical understanding, time, authority and means to reduce demand, challenge output, stop further action or recover.
The faded reference marks where we think we are, while the moving point illustrates how actual conditions can drift. This is an illustrative possible journey, not a measured trajectory or claim that all AI output is workslop. Organisational choices and usable feedback shape whether people can detect and respond to a convincing mistake in their actual work.

Skills that protect margin
- 🔎
Systems understanding
Trace how AI shifts cost, workload and risk across the system.
- 🧠
Critical judgment
Challenge plausible output and test it against the real work.
- 🔄
Adaptation and recovery
Notice drift, revise mental models and act before margin runs out.
Learning Opportunities by Dr. Cat Hicks
Build expertise with guided exercises while coding with AI.
Expertise turns warnings into protective action.
Rasmussen directs attention to how locally reasonable decisions interact across the whole system. AI can change cost, effort and the pace of proposed action. Expertise helps people see those interactions, question plausible explanations and recognise when a plan no longer fits. Protecting margin requires useful feedback and the capacity to act on it. Crossing the dotted line begins consuming the protected buffer before the actual functional boundary. It does not establish that harm has already occurred.

Tool vs Operator
- 🧰
AI assists the operator
Explore, diagnose and test, with people checking the result.
- 🎛️
AI acts in the system
Bound its permissions and pace, retain authority to stop and recover.
Test people, tools and workflow together.
AI can assist diagnosis, testing and explanation, and can also be authorised to act. It can change existing feedback and action channels. The distinction changes what must be bounded and observed. People need useful evidence, practical understanding and enforceable authority to interrupt or recover. Evaluate the joint workflow with relevant baselines and both helpful and misleading outputs. The clinical joint-performance research motivates this question but does not estimate software or LLM risk. Whether an application helps depends on its use and evaluation, not the label “tool” or “operator”.

We have to adapt
- 💸
Economic: Count generation, verification, operation and switching costs.
- 😢
Workload: Match AI output to the team’s ability to understand and check it.
- 💥
Performance: Test the work, including plausible AI mistakes and recovery.

Error margin: Give people time, expertise and authority to turn signals into action.
Local savings can create pressure elsewhere.
The same three constraints remain: economic viability, acceptable workload and acceptable performance. AI can save effort in one place while moving verification, maintenance or recovery work elsewhere. Count the whole workflow and protect the people who interpret warning signals and own corrective action. Error margin is a protected performance-side buffer, not an SLO error budget or a fourth constraint. These proposed responses need local evidence and adjustment as conditions change.

Expertise, coordination and judgment help us respond when plans no longer fit.
Use AI to strengthen our capacity to understand, act and recover.
Adaptive capacity is developed before surprise and renewed through everyday work. Expertise, shared understanding and coordination help people change plans when familiar responses are no longer enough. They also need time, resources and authority to act. AI can contribute to that capacity when its use supports understanding and effective action. The aim is sustained joint performance and recoverability. This is the talk's application of resilience engineering, not a guarantee that humans or tools can absorb unlimited pressure.

Socio Technical Systems
...in organizational development (Socio Technical Systems) is an approach to complex organizational work design that recognizes the interaction between people and technology in workplaces.
A socio-technical system cannot be understood by examining either people or technology in isolation.
The visual contrasts studying people and technology separately with seeing people as part of the system. Its connections emphasise the interactions between them.
This names the system the talk will examine and prepares Rasmussen’s control hierarchy.
People are part of control
People and organisations are adaptive components and controllers within the socio-technical system, not an external human input. Locally sensible adaptations can preserve control, or interact to create conditions for failure. Rasmussen connects effective control with usable objectives, feedback, competence, coordination and commitment.
