Hi There,
I have a question about the inputs related to sprint planning. According to the scrum guide, there are 4 inputs for this event: Product Backlog, the latest product Increment, projected capacity of the Development Team during the Sprint, and past performance of the Development Team.
However I have read from some links and tutorials on internet, and even on the official class from scrum.org that there are 2 more others items composing the inputs, beyond the 4 listed above: The Definition of Done and Restrospective Commitments.
