According to the PMBOK Guide, 7th edition, the project success criteria and objectives are the measurable terms that define what the project is intended to achieve. They are usually defined by the customer or sponsor, and agreed upon by the project manager and other stakeholders. They provide the basis for project planning, monitoring, and evaluation. Therefore, the project manager should understand the project success criteria and objectives first, before performing any other actions, to ensure that the project is aligned with the customer’s or sponsor’s expectations and requirements. The project success criteria and objectives are typically documented in the project charter, which is the key output of the Develop Project Charter process. The project charter also contains other information, such as the project purpose, scope, assumptions, constraints, risks, and stakeholders, that the project manager should review and understand. References:
