Your organization requires all Increments to pass user acceptance testing (UAT) before it is allowed to be released to production.
Is it a good idea to postpone UAT until the end of the project to prevent the Development Team from being disrupted during the Sprints?

A. No, because the state of the Product Increment won't be transparent and the feedback loop would be too long.
B. It depends on the team's Definition of Done.
C. Yes, because the Development Team is a self-organizing team and should not be disrupted during development.
D. Yes, because UAT is done in a hardening Sprint before the release Sprint.
