What powerful questions does Scrum help you answer?

The video on powerful questions made me think about the deeper purpose of the various Scrum activities. Can I formulate Scrum as a series of Powerful Questions to be general enough, that they might be useful outside of software development? Here is the image I came up with and below are the questions I think each of the Scrum Activities and artefacts strives to help you answer.

Sprint

• The Sprint is a container to limit ourselves to setting reasonable medium-term goals. 
• What can we reasonably expect to accomplish by the end of the sprint?

Vision

• How will our efforts make the world a better place?
• Who needs our product and why?
• Why should we build it?

Product Backlog

• What characteristics should our product have?
• What goals must we accomplish to achieve our vision?

Backlog Refinement

• What could we do to get us closer to our vision?
• What small steps could take us nearer to our goal?
• How can we make the steps smaller and more likely of success?

Sprint Planning

• Part 1 – What is the best possible step forward, given what we know today?
• Part 2 – How can we accomplish these steps?

Daily Scrum

• What are our goals for the day?
• How will we accomplish them?
• What help do we need?
• Who needs to talk about what?
• What could be slowing us down?

Sprint Review

• What have we accomplished or learned?
• How does this change our vision?

Retrospective

• How can we work more effectively?
• What could be slowing us down?

Definition of Done

• How do we know a step was successful?
• How do we ensure the quality of our work?
• How do we know that what was done in the last sprint is still done in this sprint?
