What's covered

An excerpt of the full document. Request access above for the complete asset — including diagrams, templates and code where applicable.

  1. 01

    The RPA ceiling and the agentic alternative

    RPA excels at stable, rule-based, structured tasks. Most enterprise work is unstable, semi-structured and exception-rich. This chapter maps where RPA still wins, where agents take over, and why the coexistence phase matters.

  2. 02

    Portfolio triage: retire, replace or coexist

    A 5-question framework for classifying every bot: stability, data shape, exception rate, business criticality and change frequency. Includes a decision matrix and migration sequencing model.

  3. 03

    Agent design for document and exception work

    Document extraction, classification, validation and reasoning patterns. How agents handle missing data, conflicting signals and exceptions without breaking the process.

  4. 04

    Tool contracts and system integration

    How agentic agents call ERP, CRM, ITSM and document stores through typed APIs and idempotent actions. Includes fallback patterns when a downstream system is unavailable.

  5. 05

    Governance, risk and audit

    Policy gates, approval workflows, evidence trails and model-risk management. Control mappings for SOX, internal audit and industry regulators.

  6. 06

    Migration roadmap and ROI proof

    A 12-month migration cadence: pilot, coexist, retire and scale. Includes the business case template and KPI framework used with Fortune 500 operations leaders.

Frequently asked

Questions enterprise readers ask

Do we have to rip out existing RPA?

No — and we usually don't. The playbook uses a coexist-and-retire model where agents handle judgment-heavy steps and RPA handles stable, high-volume mechanical steps until the agent proves it can take over safely.

Which processes should we automate first?

Start where documents, exceptions and structured data intersect: invoice processing, claims intake, purchase-order validation, contract review and HR onboarding paperwork. These have high pain, clear ROI and manageable blast radius.

How do we prove ROI to the CFO?

The playbook includes a working business-case template built on cost-per-transaction, exception-handling effort, throughput uplift and FTE redeployment. Most clients see payback within 6–9 months on the first process family.
