How often can the number of Scrum Teams working on the same Product change?

The number of Scrum Teams working on the same Product can be adjusted as needed, taking into account potential short-term impacts. This flexibility is essential for adapting to changes in workload, project demands, or the capacity of the organization. For example, if the scope of work increases or decreases, or if there are resource constraints, it may be necessary to add or reduce the number of Scrum Teams.

This adaptability allows for a more responsive and efficient approach to product development, ensuring that the teams can be aligned with the current priorities and that the effort is balanced against any potential risks or challenges that may arise from changing the number of teams. In this context, considering short-term impacts means being mindful of how such changes could affect collaboration, communication, and team dynamics, which are critical in a Scrum environment.
