Explanation
The project charter is a document that formally authorizes the project and defines its high-level scope, objectives, assumptions, constraints, and stakeholders1. The project charter is usually created by the project sponsor or initiator, but it should also involve the input and agreement of all the key stakeholders, including the business and project stakeholders, as well as the technology suppliers2. By including all stakeholders in the creation of the project charter, the project manager can ensure that their expectations, requirements, and interests are aligned and clarified, and that they have a common understanding of what the project aims to deliver3. This can help avoid or reduce conflicts, ambiguities, or changes in the project scope later on.
