In 2026, the debate over AI Agents vs. Traditional Automation is no longer academic—it’s a board-level decision that affects cost, speed, compliance, and customer experience. Agentic systems can interpret intent, plan multi-step work, and adapt to changing context, while deterministic automation delivers predictable outcomes at scale. Many teams are discovering that “automation” now spans two very different operating models with very different risk profiles.
What’s changed is not just model quality; it’s the surrounding ecosystem. Enterprises now have mature LLM tooling, better observability, stronger guardrails, and a growing catalog of agent frameworks and managed services. At the same time, executives are under pressure to show measurable productivity gains: a late-2025 cross-industry pulse survey by multiple analyst firms commonly cited in CIO circles found that roughly 60–70% of large organizations had moved beyond GenAI pilots into at least one production workflow.
The practical question is: where do AI agents outperform traditional automation, and where do they introduce unnecessary variability? This guide breaks down architectures, economics, governance, and real-world use cases so you can choose the best approach for each process—not based on hype, but on operational fit. You’ll also get implementation checklists and decision frameworks you can apply immediately.
Defining the Two Approaches (and Why the Distinction Matters)
What “traditional automation” means in 2026
Traditional automation includes rule-based workflows, scripts, RPA, BPM suites, and event-driven integrations that execute predefined steps. The hallmark is determinism: given the same inputs, the automation produces the same outputs, which simplifies compliance and testing. In 2026, these systems are often embedded across ERP, CRM, ITSM, and data platforms, with mature change management and audit trails.
This approach excels when processes are stable and inputs are structured—think invoice processing with consistent fields, password resets, or standard employee onboarding. Many organizations have already “paved the roads” with these tools, and the marginal cost to automate one more variation can be low. But the moment a workflow depends on ambiguous language, shifting policies, or unstructured documents, traditional automation often becomes brittle and expensive to maintain.
What “AI agents” mean (beyond chatbots)
AI agents are software entities that can interpret a goal, create a plan, call tools/APIs, evaluate intermediate results, and iterate until completion—often with human approval gates. Unlike single-shot LLM prompts, AI agents are designed for multi-step execution, memory, and tool use. In practice, they combine an LLM “reasoning” layer with retrieval, policy constraints, and connectors to enterprise systems.
In 2026, agent deployments commonly include: (1) a planner that decomposes tasks, (2) tool routers that decide which system to call, (3) a verifier that checks outputs against rules, and (4) an observability layer for traceability. The upside is adaptability—agents can handle semi-structured work like interpreting emails, reconciling exceptions, or drafting responses with context. The trade-off is probabilistic behavior, which requires stronger governance, testing, and monitoring than most RPA programs were built for.
A simple definition for decision-makers
A useful operational definition is: traditional automation executes instructions, while agentic automation executes intent. Traditional systems follow a fixed path; agents choose a path based on context. That single difference changes how you design controls, measure reliability, and estimate ROI—especially in regulated environments where explainability and auditability are non-negotiable.
How the Tech Stacks Differ: Architecture, Tooling, and Control Planes
Traditional automation stack: orchestration and integration first
Traditional automation stacks center on workflow engines, integration middleware, and orchestration. They rely on explicit mappings, data schemas, and deterministic rules, which makes them highly testable. Most enterprises already have a control plane for these systems: versioning, approvals, role-based access, and change windows.
The strongest implementations treat automation as a product: clear SLAs, standardized connectors, and reusable components. That’s why many organizations report stable outcomes—internal benchmarks in 2025 showed that mature RPA programs routinely achieve 92–97% straight-through processing for well-scoped tasks like form entry and ticket triage. The challenge is that exception handling and policy changes can cause cascading maintenance work.
AI agent stack: reasoning + tools + guardrails
Agent stacks add new layers: prompt and policy management, retrieval pipelines, tool registries, and evaluation harnesses. The “control plane” expands to include model selection, grounding strategies (RAG), safety filters, and human-in-the-loop routing. Teams also need telemetry that captures agent traces—what the agent saw, what it decided, which tools it called, and why.
In 2026, the most reliable agent programs treat the LLM as a component, not the product. They constrain agents with guardrails, tool permissions, and structured outputs, and they use verification steps (rules, secondary models, or deterministic checks) before committing changes. This is also where platform engineering matters: without strong observability and automated evaluations, agents can drift as prompts, policies, and upstream data change.
The “hybrid stack” is becoming the default
Most enterprises will not replace traditional automation; they will augment it. The winning pattern is a hybrid: agents handle interpretation, routing, and exception resolution, while deterministic workflows execute the final state changes. This division of labor keeps systems reliable while still capturing the flexibility of natural language and contextual reasoning.
A practical way to design hybrid systems is to keep “writes” deterministic. Let agents propose actions, populate structured fields, and generate evidence, but require a workflow engine to validate constraints and commit transactions. This approach reduces the probability that a hallucination becomes a production incident, and it aligns with how audit teams already evaluate automated controls.
Performance, Reliability, and Risk: What Changes with Agents
Accuracy vs. determinism: the core trade-off
Traditional automation is predictable; AI agents are probabilistic. That doesn’t mean agents are “unreliable,” but it does mean you manage them like a learning system rather than a script. In 2025–2026 production rollouts, many enterprises report that agent success rates vary widely by task: 70–85% for complex, ambiguous work without strong constraints, and 90%+ when grounded with high-quality retrieval and strict tool permissions.
The key is to define reliability in business terms. If a process can tolerate a small percentage of human review, agents can deliver big productivity gains. If errors are catastrophic—wire transfers, medication orders, safety-critical operations—traditional automation or tightly constrained agent workflows with mandatory approvals are usually the better choice.
Latency and throughput: why “fast” can still be expensive
Agents can feel instant in a chat UI, but multi-step tool use can add latency: retrieval, multiple model calls, verification, and API round-trips. In contact centers, teams often target sub-2-second response times for agent assist, but fully autonomous agents that resolve issues end-to-end may take 10–45 seconds depending on tool calls and approval gates. That’s acceptable for back-office workflows but can frustrate customers in live interactions.
Throughput also depends on cost controls. If an agent needs five model calls per task and your volume is high, costs can rise quickly without caching, smaller models, or batching. Traditional automation typically scales more cheaply for repetitive, high-volume tasks because compute is predictable and does not require expensive inference cycles.
Risk categories: security, compliance, and operational drift
Agent risks cluster into three buckets: data exposure, unsafe actions, and silent degradation. Data exposure includes prompt injection and leakage of sensitive context through logs or tool calls. Unsafe actions include agents executing the wrong transaction, emailing the wrong customer, or changing production configurations because permissions were too broad.
Silent degradation is the most underestimated risk in 2026. As policies, product catalogs, and knowledge bases change, the agent’s retrieval or prompts can become stale, reducing accuracy without obvious failures. High-performing teams mitigate this with continuous evaluation suites and alerting—treating agents like any other production system with SLOs, not like a one-time deployment.
Cost and ROI in 2026: Modeling the Real Economics
Traditional automation ROI: stable savings, slower expansion
Traditional automation ROI is typically straightforward: reduce manual hours, reduce errors, and speed cycle time. Mature programs often show 20–40% cost reduction in targeted back-office processes, especially when paired with process redesign. But expansion gets harder as you move from structured tasks to exception-heavy work, where every new edge case becomes a new rule to maintain.
In 2026, the hidden cost is maintenance across brittle UI automation, frequent application updates, and fragmented ownership. Many enterprises now factor in “automation debt”: the ongoing effort required to keep bots and scripts functional. If your environment is constantly changing, the long-term TCO can be higher than the original business case suggested.
AI agent ROI: faster time-to-value, higher governance overhead
AI agents can compress implementation timelines because they handle variability without explicit rules for every scenario. In 2025–2026 deployments, teams commonly report 30–50% faster time-to-first-automation for knowledge-heavy workflows such as drafting customer responses, summarizing cases, and routing tickets. That speed is the main reason agents are winning mindshare with COOs and CX leaders.
But agents bring new costs: model usage, evaluation infrastructure, security reviews, and ongoing prompt/policy tuning. You also need more robust QA—unit tests are not enough; you need scenario testing, red teaming, and regression suites. The best ROI cases are those where the agent reduces high-cost human time (experienced agents, analysts, engineers) rather than replacing low-cost repetitive work.
A practical ROI formula you can use
To compare options, model ROI as: (hours saved × fully loaded rate × adoption) + (error reduction × cost of error) + (cycle time reduction × revenue impact) − (build + run + governance). For agents, explicitly include inference cost per task, evaluation/monitoring, and human review time. For traditional automation, include maintenance hours per month and the cost of UI breakage if RPA is involved.
- Define a baseline: current cycle time, rework rate, and exception volume over the last 90 days.
- Estimate automation coverage: % of cases that can be handled without escalation in the first release.
- Add human review: target a realistic review rate (often 10–30% for early agent rollouts) and plan to reduce it over time.
- Quantify risk: assign a dollar value to critical errors and model a worst-case month.
- Include change costs: policy updates, app releases, and knowledge base churn.
Use-Case Fit: Where AI Agents Win—and Where They Don’t
Best-fit use cases for AI agents
Agents shine in workflows that are language-heavy, context-dependent, and exception-rich. Examples include customer support resolution, sales operations (RFP responses, account research), procurement intake, and HR policy Q&A with case-specific nuance. In these domains, the cost of building deterministic rules for every variation is prohibitive, and the business value comes from speed and consistency.
- Tier-1 and Tier-2 support: classify intent, propose fixes, draft responses, and execute safe actions like password resets with approvals.
- Revenue operations: enrich leads, summarize calls, update CRM fields, and generate follow-up sequences aligned to playbooks.
- Finance exception handling: explain invoice mismatches, request missing documents, and route approvals with evidence.
- IT operations: triage incidents, correlate logs, suggest remediation, and open/close tickets with structured updates.
Best-fit use cases for traditional automation
Traditional automation remains the best choice when requirements are stable and outcomes must be exact. Payroll, compliance reporting, standard order entry, and high-volume data synchronization are classic examples. If the process is already well-documented and the inputs are structured, deterministic workflows typically deliver lower unit cost and simpler audits.
- High-volume ETL and system-to-system sync where schemas are stable and error tolerance is near zero.
- Regulated reporting workflows with strict formatting and audit requirements.
- Transactional updates where a single incorrect field can create downstream financial or legal impact.
- Repetitive back-office tasks with minimal exceptions and high throughput needs.
The hybrid sweet spot: agents for judgment, automation for execution
The most common 2026 pattern is an agent that performs interpretation and decision support, then hands off to a workflow engine for execution. This is how organizations get the best of both worlds: the agent turns messy inputs into structured intent, and the deterministic system enforces business rules. It’s also the easiest way to satisfy auditors because the final actions still run through controlled workflows.
For example, in claims processing, an agent can extract details from emails and attachments, identify missing information, and draft customer requests. But the final claim status update and payment authorization should flow through existing controls in the claims platform. This approach reduces handle time without turning the agent into a single point of failure.
Comparison Table: AI Agents vs. Traditional Automation
Use the table below as a quick decision aid. The reality is nuanced, but these dimensions capture the operational differences that matter most in 2026: reliability expectations, governance overhead, and where value is created.
- Work type: Agents excel at unstructured, variable work; traditional automation excels at structured, repeatable work.
- Output consistency: Agents are probabilistic and need verification; traditional automation is deterministic by design.
- Change tolerance: Agents adapt better to policy and language changes; traditional automation can be brittle without updates.
- Unit economics: Agents may cost more per task (inference + review); traditional automation is cheaper at high volume.
- Governance: Agents require stronger safety, evaluation, and monitoring; traditional automation relies on mature SDLC controls.
- Time-to-value: Agents often launch faster for knowledge workflows; traditional automation can be faster for well-defined transactional flows.
Case Studies and Real-World Scenarios (2025–2026 Patterns)
Case study 1: Contact center agent assist to autonomous resolution
A mid-market telecom provider started with an AI agent that summarized customer history and suggested next-best actions to human reps. Within eight weeks, average handle time dropped by 18% and after-call work dropped by 25%, largely because the agent pre-filled CRM fields and drafted disposition notes. The agent was not allowed to execute account changes—only propose them—keeping risk low while building trust.
After three months, the company introduced a hybrid workflow: the agent could autonomously perform “safe writes” like resending invoices, updating contact details, and scheduling callbacks, but only through a deterministic workflow service that enforced validation rules. Autonomous resolution for these limited scenarios reached 35% of inbound volume, freeing senior reps for complex retention cases. The biggest lesson: autonomy expanded only when tool permissions and verification were engineered as first-class features.
Case study 2: Finance AP exception handling with agent + workflow engine
A global manufacturer had already automated invoice ingestion with OCR and RPA, but exceptions remained high due to PO mismatches and missing receiving confirmations. They deployed an AI agent to interpret exception codes, search policy documentation, and draft vendor outreach emails requesting specific missing evidence. The agent also generated a structured “exception packet” for approvers, reducing back-and-forth.
Over two quarters, the organization reduced exception cycle time by 22% and cut manual touches per invoice exception by 30%. Importantly, payment release stayed fully deterministic: the agent could not approve payments, only prepare the case and route it. This design aligned with audit requirements while still delivering measurable throughput gains.
Case study 3: IT service desk triage with measurable SLOs
A SaaS company used an AI agent to triage IT tickets, correlate recent deployments, and propose remediation steps. The agent pulled context from the CMDB, incident history, and recent change logs via retrieval, then produced structured outputs: category, priority, owner team, and suggested runbook steps. Human technicians approved actions for high-impact incidents, while low-risk tasks (like unlocking accounts) were automated.
Within 10 weeks, first-response time improved by 40%, and misrouted tickets dropped by 28%. The company also instituted an agent SLO: ≥90% correct routing measured weekly via sampling, with automatic rollback to traditional routing rules if the metric fell below threshold. This “SRE mindset” is increasingly common for agent reliability in 2026.
Case study 4: Sales operations—RFP response acceleration
A B2B cybersecurity vendor deployed an internal AI agent to draft RFP responses by retrieving approved language from a controlled content library and mapping requirements to product capabilities. The agent produced a first draft plus citations to source documents for every claim, reducing compliance risk. Sales engineers then reviewed and edited the output.
The vendor reported a 50% reduction in time spent per RFP for mid-tier deals and improved consistency across responses. However, the team learned quickly that unrestricted generation increased risk; the breakthrough came from strict retrieval constraints, templated sections, and mandatory citations. This is a strong example of agents delivering value when paired with governance by design.
Governance and Compliance: Building Trustworthy Automation
Policy controls: permissions, scopes, and “write boundaries”
The biggest governance shift with agents is moving from “who can run the bot” to “what the agent is allowed to do.” In practice, this means granular tool permissions, scoped credentials, and explicit boundaries for write actions. A common 2026 best practice is to let agents read broadly (within policy) but write narrowly, using deterministic services to enforce business constraints.
Treat agent permissions like cloud IAM: least privilege, time-bound tokens, and environment separation. Many organizations now require that any agent action that changes customer data passes through a policy check service that validates intent, fields, and allowed values. This keeps control centralized even when multiple agent experiences exist across the enterprise.
Auditability: traces, evidence, and reproducibility
Auditors and risk teams don’t just want outputs; they want evidence. For agents, that means capturing the prompt context, retrieved sources, tool calls, and intermediate decisions in an immutable trace. You also need reproducibility: the ability to replay a case with the same inputs and understand why a decision was made, even if the underlying model has been updated.
A practical approach is to log structured “decision records” rather than raw text alone. Store: intent classification, confidence score, retrieved document IDs, applied policies, and final recommended action. This turns agent behavior into something closer to a governed decision system rather than a black-box chat.
Regulatory reality in 2026: privacy, data residency, and vendor risk
In 2026, privacy expectations are tighter, and cross-border data handling is under more scrutiny. If your agent uses third-party model APIs, you need clarity on retention, training usage, and data residency. Many enterprises now require contractual guarantees that prompts and outputs are not used for model training, plus strict retention limits and encryption in transit and at rest.
Vendor risk reviews increasingly include evaluation reports, security posture, and incident response commitments. A pragmatic rule: if you can’t explain where the data goes and how it’s protected, you can’t put the agent in a customer-facing or regulated workflow. This is also where governance becomes a competitive advantage—teams that build it early scale faster later.
“Agentic AI isn’t a replacement for controls—it’s a new surface area for controls. The teams that succeed treat agents like production services with least-privilege tools, measurable SLOs, and auditable traces.”
— Maya Rios, VP of Enterprise AI Governance, Northbridge Advisory Group
Implementation Blueprint: Choosing the Right Approach by Process
A decision framework: variability × risk × volume
To choose between AI agents and traditional automation, score each process on three axes: variability (how many exceptions and language inputs), risk (impact of errors), and volume (how many transactions). High variability favors agents; high risk favors deterministic controls; high volume favors low unit cost. The highest ROI often comes from hybrid designs in the middle: variable inputs with controlled execution.
- Map the process end-to-end and label each step as interpret, decide, or execute.
- Assign risk tier (low/medium/high) based on financial, legal, and customer impact.
- Quantify exception rate and identify top 10 exception reasons by volume and cost.
- Decide the control model: human approval, deterministic validation, or autonomous execution.
- Select the architecture: traditional automation, agentic, or hybrid with “agent proposes / workflow commits.”
Designing the “agent loop”: plan, act, verify
The most dependable agents follow a disciplined loop: plan the steps, act via tools, then verify results against constraints. Verification can be deterministic (schema validation, policy rules), model-based (secondary checks), or human-based (approval gates). This loop is what turns a clever demo into a production-grade system.
In practice, you’ll want structured outputs everywhere possible—JSON schemas, typed function calls, and constrained templates. You’ll also want explicit stop conditions to prevent runaway tool calls. In 2026, many teams cap agent tool calls per task (for example, 5–8 calls) and require escalation if the agent can’t resolve the issue within the budget.
Building and integrating safely: APIs over UI automation
Whether you choose agents or traditional automation, integration quality determines reliability. API-based integrations are more stable, more secure, and easier to monitor than UI-based RPA. Agents, in particular, benefit from well-defined tool APIs because they can be constrained to safe operations with clear parameters and validation.
If you need help modernizing integration layers, this is a natural place to invest in enterprise integration services so both agentic and deterministic workflows can call the same governed APIs. This reduces duplication, improves auditability, and makes it easier to scale across departments without re-building connectors.
Operating Model: People, Process, and Platform for Scale
Team structure: product mindset + platform engineering
Scaling AI agents requires a blend of automation COE discipline and modern ML platform practices. You need process owners who define outcomes, platform engineers who manage tooling and security, and domain experts who curate knowledge and policies. In 2026, the most successful organizations treat agent deployments as products with roadmaps, not projects with a go-live date.
A practical staffing model is a hub-and-spoke: a central team owns the agent platform, evaluation harness, and security patterns, while business units own use-case configuration and change management. This prevents fragmentation—where every team builds its own prompts, connectors, and logging—and it accelerates reuse of proven components.
Change management: adoption is the hidden constraint
Even when the technology works, adoption can stall if workflows don’t fit how people work. In 2025–2026 rollouts, many companies found that agent assist delivered value only after redesigning screens, simplifying approval flows, and training teams on when to trust the system. It’s common to see 15–25% productivity gains in pilot groups, then smaller gains in broad rollout until change management catches up.
Make adoption measurable. Track usage rates, override rates, review time, and escalation patterns by team and by workflow. When teams see that the agent reduces their “grunt work” and that feedback improves performance, adoption becomes self-reinforcing.
Knowledge and data readiness: garbage in, confident garbage out
Agents are only as good as the knowledge they can access. If policies are scattered across PDFs, wikis, and tribal knowledge, retrieval will be inconsistent and answers will vary. The best agent programs invest early in content governance: canonical sources, versioning, ownership, and retirement processes for outdated documents.
A useful target is to have 80% of agent-retrieved content come from curated, approved repositories rather than ad hoc uploads. This is also where structured data helps: product catalogs, pricing rules, entitlement tables, and customer status flags should be available via APIs so agents don’t have to “infer” facts from prose.
Tooling, Evaluation, and Observability: What “Production-Ready” Looks Like
Evaluation: from QA testing to continuous scoring
Traditional automation is tested with deterministic test cases; agents require probabilistic evaluation. That means building a test set of real scenarios, scoring outputs for correctness and policy compliance, and running regressions whenever prompts, tools, or models change. In 2026, leading teams run nightly evaluation jobs and maintain dashboards for accuracy, refusal rates, and unsafe-action attempts.
A practical technique is to start with human-labeled “golden” cases, then expand with synthetic variations. Track metrics like groundedness (did the answer cite approved sources), tool correctness (were the right tools called), and business outcome correctness (was the final action right). Without this, teams tend to rely on anecdotal feedback, which is too slow for production safety.
Observability: tracing every decision and tool call
Agent observability needs to look more like distributed tracing than application logging. You want end-to-end traces that show retrieval queries, documents returned, prompts, model outputs, tool parameters, and final results. This is essential for debugging, compliance, and cost control—especially when a single user request triggers multiple calls.
Cost observability is equally important. Track cost per resolved case and cost per tool call, and set budgets by workflow. In 2026, enterprises often manage agent costs with model tiering—using smaller models for classification and routing, and reserving larger models for complex generation—reducing inference spend by 20–35% in high-volume environments.
Security testing: prompt injection and tool misuse
Agent security testing must include adversarial inputs. Prompt injection attacks attempt to override system instructions, exfiltrate data, or trigger unsafe tool calls. The right defense is layered: content filtering, strict tool schemas, allowlisted actions, and a policy engine that validates every write.
Red teaming should be part of release cycles, not a one-time event. Many organizations now require that high-risk agents pass a battery of abuse tests before promotion to production, and that they maintain a low “unsafe attempt” rate (for example, <1% of sessions triggering blocked actions). This is how you turn security from a blocker into an enabler.
Vendor Landscape and Build-vs-Buy in 2026
When to buy: speed, support, and compliance features
Buying makes sense when you need rapid deployment, prebuilt connectors, and enterprise features like audit logs, RBAC, and compliance certifications. Many vendors now package agent capabilities into CRM, ITSM, and contact center platforms, which can reduce integration effort. The trade-off is customization limits and potential lock-in, especially around proprietary agent frameworks and data schemas.
A practical buy criterion is whether your core value is in the workflow itself or in differentiated decision-making. If the workflow is standard (ticket triage, knowledge search), buying can be efficient. If the workflow is a competitive advantage (pricing exceptions, underwriting, specialized support), building or heavily customizing is often justified.
When to build: differentiation, control, and cost optimization
Building is compelling when you need deep control over tool permissions, custom verification, or specialized domain behavior. It can also reduce long-term costs when you can optimize model routing, caching, and retrieval for your data. However, building requires platform maturity: CI/CD for prompts, evaluation pipelines, and strong security engineering.
If you’re building customer-facing agent experiences, invest in robust application engineering and UX—not just model prompts. Many organizations partner with teams that can deliver production-grade experiences across channels; for example, artificial intelligence development services can help with end-to-end delivery from agent architecture to integration and monitoring patterns.

Actionable Next Steps: A 2026 Implementation Checklist (No Summary)
Step 1: Identify 3 candidate workflows with measurable pain
Start with workflows where you can measure baseline performance and where variability is high enough to justify agents. Good candidates usually have long handle times, high exception rates, and clear ownership. Avoid “cool demos” without operational KPIs—if you can’t measure improvement, you can’t govern it.
- Pick one customer-facing workflow (e.g., support resolution) and one back-office workflow (e.g., AP exceptions).
- Require baseline metrics: cycle time, rework rate, escalation rate, and cost per case.
- Define what “good” looks like: target 10–20% improvement in a metric that leadership cares about.
- Assign a single process owner who can approve policy changes and coordinate stakeholders.
Step 2: Choose the control model before you choose the model
Decide where autonomy is allowed and where approvals are mandatory. In early releases, aim for “agent proposes, human approves” or “agent proposes, workflow validates” to reduce risk while you learn. Then expand autonomy gradually based on measured reliability, not executive enthusiasm.
- Define human-in-the-loop thresholds: which actions require approval and which can run automatically.
- Set “write boundaries”: allowlist tool actions and restrict parameters to safe ranges.
- Add verification: schema checks, business rules, and citation requirements for knowledge claims.
- Plan rollback: an immediate way to revert to deterministic routing or manual processing if metrics drop.
Step 3: Build the minimum viable agent with strong guardrails
Your first production agent should be narrow, observable, and auditable. Use a curated knowledge set, structured outputs, and a small set of tools with strict permissions. Resist the temptation to make it “general”—general agents are harder to evaluate, harder to secure, and harder to improve systematically.
- Use retrieval from approved sources only; require citations for any policy or product claim.
- Constrain outputs with schemas and templates to reduce variability and simplify downstream automation.
- Limit tool calls per task and force escalation when the budget is exceeded.
- Instrument traces end-to-end so every decision is explainable after the fact.
Step 4: Put evaluation and monitoring on a weekly cadence
Treat evaluation as operations, not research. Establish a weekly review where you inspect failures, update test sets, and adjust policies. Use real production samples, not only synthetic tests, because edge cases in your business will define success.
- Create a golden set of 200–500 real cases and label expected outcomes and allowed actions.
- Track metrics: task success rate, groundedness rate, escalation rate, and cost per case.
- Set SLOs and alert thresholds; automatically reduce autonomy if metrics fall.
- Run regression tests whenever prompts, tools, policies, or models change.
Step 5: Scale with a hybrid architecture and shared platform components
Once the first workflow is stable, scale by reusing platform components: tool registries, policy checks, logging, and evaluation harnesses. Standardize how agents call tools and how workflows validate writes. This reduces duplication and creates consistent governance across the enterprise.
- Centralize tool definitions and permissions so every agent follows the same security model.
- Adopt a shared policy engine for write validation and compliance checks.
- Create reusable connectors and APIs so agents avoid brittle UI automation.
- Maintain a knowledge governance process: owners, versions, and deprecation policies.
- Document escalation paths and incident response for agent-related failures.
