This breadth ensures that the team addresses all necessary elements to deliver a complete product increment.

Non-functional requirements are vital for the system's overall quality but are often not directly related to specific features. Including them in the sprint backlog helps ensure that the team does not overlook important aspects of software quality during development. Thus, by appropriately mixing both types of work, the sprint backlog supports a holistic approach to delivering valuable software.

For example, stating that it includes only functional requirements would ignore the critical non-functional aspects necessary for a well-rounded product.
