An Acceptance Management Process is a formal method for reviewing project deliverables to confirm they meet acceptance criteria before the customer signs off. It involves completing review techniques documented in the project acceptance plan. The process ensures each deliverable is completed, documented, reviewed, and approved. It is undertaken towards the end of a project as deliverables are finished, and can involve individual, grouped, or final sign off of all deliverables. Without this process, customers may not accept final project deliverables.
