Acceptance Criteria

C.

Acceptance criteria are measurable criteria that define the attributes or characteristics of a product or deliverable that must be met in order for the stakeholders to accept it as complete and satisfactory. These criteria are typically developed during the planning phase of a project and are used to guide the development and testing of the product or deliverable.

Option A is not correct because it refers to the approach used to prove whether the project's products have been completed, rather than the specific criteria used to determine if the products are acceptable.

Option B is not correct because it refers to a measurable improvement resulting from a project outcome, which is not the same as the criteria used to determine whether the outcome or deliverable is acceptable.

Option C is the correct answer because it refers to the measurable definitions of the attributes for a set of products to be acceptable to key stakeholders. Acceptance criteria are the specific requirements that must be met in order for the stakeholders to accept the product or deliverable.

Option D is not correct because it refers to project controls set up during the process of initiating a project, which is not related to the development of acceptance criteria. Project controls refer to the processes and procedures used to manage the project's scope, schedule, budget, and quality, whereas acceptance criteria refer specifically to the measurable characteristics that must be met for a product or deliverable to be accepted.
