Final answer:
Developers should have the ability to contact the product owner to clarify work aspects during a sprint to ensure project success, while balancing productivity and communication.
Step-by-step explanation:
During a sprint, developers should be able to contact the product owner to clarify aspects of the work. This collaboration is essential to ensure that the work meets the product owner's expectations and adheres to the project requirements. While developers should strive to work independently and minimize the need for supervision, the availability of the product owner for necessary clarifications contributes to the success of the sprint. It is not necessary to be in twice-daily contact with the product owner, nor should developers be completely uninterrupted. The key is to find a balance that allows productivity without excessive disruption.
