Direct implementation cost can include workflow mapping, schema design, integration, testing, security and privacy review, migration, and training. Operating cost can include event processing, model or tool use, storage, indexing, retrieval, access administration, reviewer time, reconciliation, incident response, and evidence maintenance when sources or policies change. Some costs are fixed for a workflow, while others vary by case volume, evidence depth, and retention.
Record predicted and actual cost at a useful grain, such as workflow, case type, model or provider, and review tier. Distinguish quoted, reserved, consumed, charged, refunded, accrued, invoiced, and settled amounts where applicable. An internal credit or capacity measure can support allocation and control but does not eliminate an external supplier cost. Reconciliation status belongs beside the number so decision makers know whether it is estimated or confirmed.
