Project Objectives
What does the customer expect to get from this project, when, and for how much expenditure of resources? The answer to that question is called the Project Objective.

Notice the specificity of the question – not “why,” but “what, when, and how much.”

The question of “why” generally relates to an expected business outcome, often called the “goal” or “mission.” The project team is challenged to develop a specific approach with measured results that will satisfy the goal or mission. This specific approach, along with relevant constraints, is called the project objective.

When the project objective is understood and agreed among the stakeholders (performing organizations, senior management, team members and their line managers, and the customer), then you have achieved the corresponding behavior of agreement.
