# How to implement a workflow platform
Start with one complete route through the work, prove that people can use it and expand from evidence gathered in live operation.
## Choose a process with a clear end
For an operations leader replacing email and spreadsheet coordination, the first task is to define what finished means. Choose a route with a named owner, observable handovers and a measurable delay. Collect a typical case, an exception and a failed case. Map what actually happened rather than relying only on the written procedure.
## Agree states, evidence and authority
For each stage, record who can act, what information they need and what allows work to advance. Include returns, cancellations, delegation and reopened decisions. Decide which system owns the client, case and document records. Those decisions form the acceptance criteria for the first release and expose gaps that a screen design alone will miss.
## Build one complete route
Connect intake, work allocation, review and completion for the chosen case type. Integrate only the systems needed to carry that work. Bring users into the build with representative cases and check permissions as each role. An attractive prototype that cannot handle a rejected approval is not ready to replace the existing process.
## Plan migration and recovery
Agree which open cases move into the platform, how historic evidence remains accessible and when the old process stops accepting new work. Assign a support owner and define a fallback if a critical integration fails. A pilot can run alongside the existing process briefly, but indefinite double entry hides the real operating cost.
## Measure the first release
Establish elapsed case time, time waiting for review and the number of returned cases before rollout. Compare equivalent case types after adoption and inspect the reasons behind changes. Add the next route when users can complete the first reliably and the operation has someone who owns configuration, support and improvements.
## What determines cost and duration
The main drivers are the number of process variants, integration access, data migration, permission rules and assurance requirements. Request an estimate against a bounded first release with explicit assumptions. A supplier should explain the work excluded, the client decisions needed and how operating costs change as use grows.
