Hi Hussam,
Below is some info for you with more reference material to read if you like.
Agile Product Vision —
From PMI’s Learning Library:
Agile project management with Scrum
The Product Owner represents the single voice of the customer, and creates, manages, and owns the Product Vision. The Product Vision details the purpose of a Product, the aim with which the Product is being created and what it intends to achieve for customers and users. The Product Vision describes a future shape of the Product and what problems it tries to solve or what ambitions it tries to achieve.
The Product Owner may conduct a Strategy Meeting at the beginning of a project with key management Stakeholders, a Project Manager/Coach, and a Scrum Master. Strategy Meetings are driven by a vision associated with a specific strategic business need or goal. The Product Owner leads the planning session, establishes ground rules, and documents the outputs. The vision is framed as a strategy with associated goals and objectives. Out of the Strategy Meeting will come the artifact, the Product Vision Statement.
The Development Team would be involved next in a Release Planning Meeting where the Product Vision would be reviewed.
Agile Project Charter —
From the
Agile Practice Guide, ©2017 PMI, pp. 49-50.
5.1 Chartering the Project and the Team
A servant leader may facilitate the chartering process. A team can coalesce by working together, and the project charter is a great way to start working. In addition, team members may want to collaborate to understand how they will work together.
At a minimum, for an agile project, the team needs the project vision or purpose and a clear set of working agreements. An agile project charter answers these questions:
• Why are we doing this project? This is the project vision.
• Who benefits and how? This may be part of the project vision and/or project purpose.
• What does done mean for the project? These are the project's release criteria.
• How are we going to work together? This explains the intended flow of work.
Hope this helps in your understanding.
