This process group covers supporting products once they have been sold. It includes registering products, receiving and validating warranty claims, investigating failures through field service visits and root cause work, deciding who is responsible, handling pre-authorisations, approving or rejecting claims, notifying the claimant, authorising payment, closing the claim and reconciling the outcome. It also covers recovering costs from suppliers and delivering service to individual customers, from confirming their requirements and building a service order to scheduling resources, carrying out repairs and collecting feedback on quality.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
