What document summarizes the project’s aims, deliverables, and success criteria?

The document that summarizes the project’s aims, deliverables, and success criteria is the Project Brief. This document serves as a foundational reference during the project initiation stage as it clearly outlines what the project is about and what it seeks to achieve. It captures the essence of the project, including its objectives and the key outputs that are expected to be delivered.

The Project Brief also includes success criteria, which are essential for measuring the project’s success upon completion. These criteria provide benchmarks against which the project's performance can be evaluated. Overall, the Project Brief is crucial for ensuring that all stakeholders have a clear understanding of the project before it commences, facilitating better planning and execution.

In contrast, the other options serve different purposes within the project framework. The Project Mandate typically provides the authority and initial justification for the project, but it does not go into the level of detail regarding aims and deliverables. The Project Approach outlines how the project will be executed, focusing on methods and strategies, rather than summarizing its aims. The Business Case assesses the project's viability and justifies the investment but does not summarize the specific aims and deliverables as the Project Brief does.
