Pilot autonomous task routing with a step-by-step ROI kit—baselines, metrics and results templates to prove value in 6–12 weeks.

Cut routing chaos: a practical case study kit to prove ROI with autonomous agents

Manual task routing creates hidden tax across operations: missed deadlines, unclear ownership, and repetitive handoffs that eat up skilled time. This kit gives you a step-by-step pilot plan, measurement framework, and ready-to-use results templates so you can pilot autonomous agents for task routing and prove the ROI in 6 612 weeks.

Why measure ROI for autonomous task routing in 2026?

Autonomous agents are moving from developer labs to knowledge workers' desktops (see Anthropic's Cowork release in Jan 2026) and large-scale enterprise pilots are now common. But adoption without measurement leads to "productivity illusions"—apparent speed gains followed by increased cleanup and inconsistent outcomes (a key 2026 theme reported across industry outlets). You need a rigorous, repeatable plan to show real value.

What this kit gives you

A compact case study template to communicate to stakeholders.
A measurable baseline & metrics plan for routing pilots.
Statistical testing and ROI calculation steps with a worked example.
Results templates and decision criteria for go/no-go or phased rollout.

Executive summary (one-paragraph template)

Use this in your pilot brief: We will pilot an autonomous routing agent on [task type] across [team(s)] for [pilot duration]. Success is defined as a X% reduction in average routing time and a net positive ROI within Y months, measured against a documented baseline. The pilot will run as an A/B or phased rollout, with human-in-the-loop guardrails and continuous monitoring of accuracy, SLA adherence and task reassignments.

Step-by-step pilot plan

Define scope & stakeholder map (Week 0)

Pick a single, high-volume task type with clear routing rules—examples: support tickets, invoice approvals, inbound leads, or content tagging. Identify business owner, data owner, platform owner and a change champion. Limit scope to 1 63 teams to reduce variability.
Set clear hypotheses and success criteria

Example hypothesis: "Autonomous routing will reduce median routing time by 60% and reduce misrouted tasks by 50% without increasing SLA breaches." Convert success criteria to numeric thresholds (e.g., routing time, reassignment rate, SLA breaches).
Instrument & capture baseline (Weeks 1 64)

Collect 4 88 weeks of baseline data. Instrument the systems where tasks are created and routed (Jira, Zendesk, Slack, Google Drive, CRM). Ensure timestamps for task creation, assignment, owner acceptance, reassignment and closure are logged. Document current manual steps and average time per step.
Design the agent and guardrails (Week 2 63)

Decide the agent's autonomy level: suggest-only, auto-assign with human confirm, or fully auto with audit logs. Build fallback rules for ambiguous cases, confidence thresholds, and a clear escalation path. Log every decision and confidence score for later analysis.
Run the pilot (Weeks 4 612)

Choose randomized A/B or phased rollout. Keep communication open with users and collect qualitative feedback. Monitor metrics daily and do formal analysis at 4 and 8 weeks.
Analyze, document results & recommend next steps (Week 12)

Run the statistical tests, compute ROI, and produce a concise decision memo with go/no-go, phased expansion plan, and data-driven suggestions to improve agent rules.

Core metrics to track (definitions and why they matter)

Pick 6 610 metrics—track both efficiency and quality to avoid the "speed at the cost of cleanup" trap.

Routing Time (TTF: time-to-first-assignment) — time from task creation to assignment to an owner. Decreases show immediate efficiency gains.
Time-to-Owner Acceptance — time from assignment to owner acknowledgment. Measures accuracy of routing and recipient fit.
% Auto-Routed — share of tasks routed by the agent vs manual. Tracks adoption and coverage.
Reassignment Rate — percent of tasks reassigned within X days. High rates indicate misrouting and higher downstream cost.
Error Rate / Misroute Rate — proportion of tasks incorrectly routed (measured via tags, reassignments, or manual QA).
SLA Breach Rate — percent of tasks missing SLA targets; critical for customer-impacting processes.
Work Minutes Saved — (baseline routing minutes minus pilot routing minutes) across population. Convert to FTE equivalence and dollars.
Cost per Task — total processing cost divided by number of tasks, before and after.
User Satisfaction / Qualitative Score — short surveys for owners and requesters to capture perceived value and trust.

Baseline measurement: practical tips

Collect uninterrupted data for at least 4 weeks; 8 weeks if your volume fluctuates seasonally.
Validate timestamps and reconcile across systems—misaligned clocks or missing events will invalidate comparisons.
Segment by priority and task type. High-priority tasks can behave very differently from low-priority volume.
Capture human effort per routing action (e.g., average 10 min per routing decision) through time logs or quick time-and-motion sampling.
Record associated costs: hourly fully-burdened rate for routing roles, third-party vendor costs, and existing automation maintenance costs.

Baseline advice: you can’t prove improvement without a stable baseline. Spend up to 25% of pilot time on making the baseline accurate.

Pilot design patterns

Randomized A/B (recommended for statistical rigor)

Randomly assign incoming tasks to control (manual) or treatment (autonomous agent). This isolates agent effects from temporal trends. Ensure sample size supports detection of your expected effect size (see power calculation below).

Phased rollout (practical operational approach)

Turn the agent on for a single team, iterate, then expand. Use when you need quick operational learning and close collaboration with users.

Confidence-threshold auto-assign

Auto-assign only when model confidence ≥ X%; otherwise, fall back to suggested routing. This reduces misroutes during early stages.

Statistical testing & power calculations

Don’t just eyeball averages. Use tests appropriate to metric type:

Continuous metrics (routing time): t-test or non-parametric Wilcoxon test if distributions are skewed.
Proportions (reassignment rate, error rate): chi-square or two-proportion z-test.
Use confidence intervals rather than just p-values; report effect sizes (e.g., median reduction in minutes).

Quick power rule-of-thumb: for detecting a 20% reduction in median routing time with α=0.05 and power=0.8, you typically need several hundred to a few thousand events depending on variance. If your variance is high, increase sample size or stratify by task type.

ROI calculation: formulas and worked example

Key variables

V = monthly task volume
Tb = baseline average routing time per task (minutes)
Tn = new average routing time per task (minutes)
H = fully-burdened hourly cost ($/hour) of routing labor
Cagent = annual cost of agent (licenses, infra, implementation amortized)
Sother = other measurable savings (reduced escalations, faster close rate, NPS-driven revenue impact)

Compute monthly labor savings

Work minutes saved per month = V * (Tb - Tn)

Work hours saved per month = (V * (Tb - Tn)) / 60

Monthly labor $ saved = Work hours saved * H

Annual ROI

Annual gross savings = 12 * Monthly labor $ saved + Sother

Annual net benefit = Annual gross savings - Cagent

ROI = (Annual net benefit) / Cagent

Worked example (support ticket routing)

Assumptions:

V = 10,000 tickets/month
Tb = 10 minutes (manual routing)
Tn = 2 minutes (agent)
H = $40/hour (fully burdened)
Cagent = $180,000/year (licenses + infra + ops)
Sother = $50,000/year (fewer escalations, faster SLAs)

Work minutes saved/month = 10,000 * (10 - 2) = 80,000 minutes

Work hours saved/month = 80,000/60 = 1,333.3 hours

Monthly labor $ saved = 1,333.3 * $40 = $53,333

Annual gross savings = 12 * 53,333 + 50,000 = $700,000

Annual net benefit = 700,000 - 180,000 = $520,000

ROI = 520,000 / 180,000 = 2.89 11 289% ROI

Payback period = Cagent / Monthly net savings (53,333 - license monthly share 15,000) 180,000 / 38,333 4.7 months

This example shows how quickly an agent can pay back investment when volumes are high and per-task routing time is non-trivial.

Results templates (copy these into your final report)

Executive highlights (one paragraph)

Example: The autonomous routing pilot reduced median routing time from 10 to 2 minutes (-80%), cut misroutes from 8% to 3%, and produced an annual net benefit of $520k representing a 289% ROI. Recommendation: expand to X teams with phased ramp and tighten confidence threshold logic to reduce residual misroutes.

Metrics table (before/after)

Provide a concise table for stakeholders (CSV-ready):

Metric, Baseline (value), Pilot (value), Absolute Change, Relative Change, p-value
Routing Time (median), 10m, 2m, -8m, -80%, <0.001
Reassignment Rate, 8%, 3%, -5pp, -62.5%, 0.002
% Auto-Routed, 0%, 72%, +72pp, n/a
SLA Breaches, 3.2%, 2.7%, -0.5pp, -15.6%, 0.12
Work Hours Saved/month, 0, 1,333, +1,333, n/a
Monthly Labor $ Saved, 0, $53,333, +$53,333, n/a

Go/No-go decision checklist

Did routing time reduce by target X%?
Is misrouting rate within acceptable threshold?
Is the net financial benefit positive within Y months?
Are guardrails and audit logs in place for compliance?
Do users report neutral or positive satisfaction?

Common pitfalls and how to avoid them

Pitfall: Poor baseline data. Fix: invest time in instrumentation and reconciliation.
Pitfall: Ignoring quality metrics. Fix: track reassignment and SLA breach rates alongside speed.
Pitfall: Overtrusting confidence scores. Fix: set conservative thresholds early and monitor drift.
Pitfall: No human fallback. Fix: keep human-in-loop for exceptions and set audit windows.
Pitfall: Post-deployment cleanup. Fix: instrument for cleanup time and include it in ROI (ZDNet’s 2026 guidance emphasizes avoiding gains that require extra cleanup).

Advanced strategies & 2026 trends

As of early 2026, two trends shape pilots and long-term decisions:

Desktop autonomous agents with file-system access (e.g., research previews like Anthropic's Cowork) make it easier to route tasks that require document-level context—good for finance, legal, and content operations but heightens data governance needs.
Autonomous business architecture approaches emphasize a "data lawn": an ecosystem where clean, well-governed data powers multiple agents. If you plan scale, invest early in a centralized task and event log (as ZDNet suggests), not per-agent silos.

Advanced pilots should also test cross-agent handoffs, agent-to-agent orchestration, and integrate signals from CRM and analytics systems for prioritized routing.

Sample timeline & resource checklist

Typical pilot: 8 612 weeks

Week 0: Kickoff, scope, and stakeholders
Weeks 1 64: Baseline capture & instrumentation
Weeks 3 64: Agent rule design & guardrails
Weeks 5 610: Pilot run with daily monitoring
Week 11 612: Analysis, ROI computation, decision memo

Minimum team: product owner, data/analytics engineer, platform engineer, operations lead, and a representative from impacted users.

Actionable checklist to start today

Select a single high-volume task type and stakeholder owner.
Document current manual routing steps and capture 4 weeks of timestamps.
Define success thresholds (time, error, and ROI) and publish them.
Design an A/B or phased pilot with clear guardrails and logging.
Run simple ROI estimate using the formulas above to secure budget.

Closing—future predictions (2026 & beyond)

Through 2026 we’ll see two clear shifts: agents gain deeper access to contextual sources (documents, inboxes, CRM) enabling higher accuracy, and enterprises will demand measurable ROI and governance to scale. Teams that pair early pilots with rigorous measurement—capturing both speed and quality—will realize sustainable productivity gains and avoid the cleanup trap. The best-practice playbook evolves quickly; treat your pilot as an iterative experiment, not a one-time deployment.

Takeaways

Measure both speed and quality. Fast routing with high misroutes is a net loss.
Invest in baseline quality. Accurate baselines make your results defensible.
Start small, prove ROI, then scale. Use A/B when possible for rigor.
Include governance and audit logs. Desktop agents and file access change the risk profile.
