A fast payment platform cannot fix an unverified milestone.
Participants experience the full journey: activity completed, milestone recorded, eligibility confirmed, exception resolved, payment approved, and funds delivered. The payment rail is only one step in that chain.
Map the queue between completion and approval.
For each milestone, identify the source of truth, the person or system that verifies completion, the rule that determines eligibility, and the owner of exceptions. Then measure how long each handoff waits before someone can act.
Design for the ordinary path and the exception path.
A governed workflow should move routine milestones automatically while routing missing evidence, duplicate events, and participant questions to a named owner. That preserves human review where it matters without making every payment a manual reconciliation exercise.
Use the playbook to find the first fix.
The Participant Payment Friction Playbook helps teams separate payment-rail performance from the operational queues that happen before approval. Start with one milestone and one study, then measure time-to-approval and exception aging.
