Project Acceptance Criteria is the quality provisions including inspection and test requirement, and specified set of characteristics, descriptions of capabilities, or other useful qualities of the project results that is established the acceptability of the items defined in a checklist focused on the client expectations to control the project.
Reference Definition by Taskmanagementguide: The acceptance criteria should be defined in the planning phase – it is a product of collaborative efforts (interviews, discussions, negotiations and conclusions) of the project manager and project customer, so the team members clearly know what they should deliver to the customer, while the customer knows what he will get in a result of the project (he recognizes how his needs correlate with the project results). Project acceptance criteria serve as a checklist for project team to focus on the client expectations and for customer to control whether he has got everything he requested for (both at the end of the project and on certain intermediary milestones).
