Project success criteria are the standards by which the success of a project is judged. They include specific goals, deliverables, and performance measures such as cost, time, and quality targets. Defining these criteria during the initiation phase provides a clear understanding of what constitutes project success and guides decision-making throughout the project lifecycle.
Per the CompTIA Project+ PK0-005 exam objectives, under Domain 1.1: Explain the basic characteristics of a project and various methodologies and frameworks used in IT projects, establishing clear success criteria is fundamental for project planning and evaluation.
