A vision statement is a document that states the business need, identifies the key stakeholders, and defines the positive impact the solution will bring to the organization and stakeholders. A vision statement provides a high-level description of the desired future state and the value proposition of the solution. It also helps to align the expectations and objectives of the stakeholders and to guide the scope and direction of the project12.

The other options are not correct because:

Requirements documentation is a document that describes the capabilities, features, and qualities of the solution that will meet the stakeholder needs. It does not state the business need or the positive impact of the solution3.

Business case is a document that provides the justification for initiating a project or task. It typically includes the business need, the expected benefits, the costs, the risks, and the alternatives of the proposed solution. It does not identify the key stakeholders or define the positive impact of the solution4.

Project charter is a document that formally authorizes the existence of a project and provides the project manager with the authority to apply organizational resources to project activities. It typically includes the project purpose, objectives, scope, deliverables, milestones, roles and responsibilities, budget, and risks. It does not state the business need or the positive impact of the solution5.
