What is the primary reason for inviting external participants to Sprint Planning?

Inviting external participants to Sprint Planning primarily serves the purpose of providing valuable advice. This can include insights from stakeholders, subject matter experts, or even customers who can help clarify requirements, share important context about the project, or offer different perspectives that might improve the planning process. The expertise and viewpoints of external participants can significantly enhance the Developers' understanding of what needs to be accomplished during the Sprint.

This interaction is beneficial because it helps the Scrum Team make informed decisions about the work they can commit to, ensuring alignment with the stakeholders' needs and expectations. Having external participants present encourages collaboration and helps to foster a shared understanding of the project goals, which is crucial in a Scrum environment.
