Thetypical size of an effective Scrum Team is ten or fewer people, as stated in the2020 Scrum Guide. This includes the Product Owner, Scrum Master, and Developers. Smaller teams ensure better communication, collaboration, and effectiveness, as larger teams can introduce inefficiencies and coordination challenges.
Why the other options are incorrect:
* B. Size doesn't matter as long as the Scrum Master coordinates the work in collaboration with the Product Owner:Scrum Teams are self-managing and self-organizing; they do not rely on the Scrum Master to coordinate work. Team size does matter for effectiveness.
* C. Bigger teams communicate better, are more productive and produce better results:Larger teams often face communication and coordination challenges, reducing productivity and effectiveness.
* D. When a team expands beyond ten, activities, like verification and operations, are assigned to a different team:Scrum encourages cross-functional teams that handle all activities required to deliver a usable Increment without assigning work to other teams.
