Is it a good practice to have at least two Product Owners on big projects?

Having more than one Product Owner on a project can lead to confusion about direction and priorities, as the role of a Product Owner involves being the single point of accountability for maximizing value and providing clear guidance to the Scrum Team. The Scrum framework promotes having one Product Owner because it ensures a unified vision for the product. This single-person responsibility allows for more straightforward decision-making and prioritization of the Product Backlog.

Additionally, having multiple Product Owners could dilute responsibilities and create conflicting priorities, which can undermine the fundamental principles of Scrum, such as clarity, focus, and collaboration. Therefore, maintaining a single Product Owner is crucial for effective communication and alignment within the team, regardless of the project's size.
