Several agents split the work, check each other’s output and pass the judgement calls to the right person. First agent live 6–12 weeks From the first workflow to daily use Ownership 100%Code, prompts and models owned by the client Starts with One workflow Usually the top use case from a readiness sprint Most agent pilots stall at the same point: the step where the agent has to act inside a real system. - 01 Agents that demo well and fail on real data. Retrieval and tool calls break on the long tail of cases. - 02 Work that crosses three or more systems. ERP, CRM, email and documents in one process. - 03 Work passed between five inboxes. Each hand-off adds a day and loses context. ## A working system, ready to run every day. Each agent ships with the parts that keep it reliable after launch: tests, traces and a clear path to a person when it is unsure. - 01 Process and agent design The target process, which steps each agent owns and when it must ask a person. - 02 Orchestration A coordinator that splits the work and checks every hand-off. - 03 System connections Validated links to the ERP, CRM, inboxes and documents. - 04 Human approval steps Low-confidence or high-impact decisions go to the right person. - 05 Evaluation suite Golden datasets that every change must pass before release. - 06 Monitoring and runbooks Every call traced, with runbooks the client team can follow. ### The same invoice, two ways of working - Email Invoice arrives in a shared inbox - Person Keyed into the ERP by hand - Email PO checked with purchasing - Person Price difference chased - Email Approval by email thread - Agent Reads and extracts the invoice - Agent Matches it to the PO - Agent Applies the approval rules - Person Approves the one exception - Agent Posts to the ERP Example Same people, different work ## Six to twelve weeks, set by the systems involved. The first agent runs alongside the team before it takes over any work. Each additional system adds connection and test time. ## Run it, extend it or hand it over. Allow-lists, audit logs and evaluations on every change, ready for the EU AI Act. Teams learn to hand their own everyday work to AI, alongside the agents. Runbooks, evaluation suites and time alongside the client’s engineers, so the team can run and extend each agent. ## Agents in daily use. ## About agent engineering. What does an agent project cost?
