"In all my analyst roles I was responsible for coordinating and leading user acceptance testing. This involved working with my clients to identify the right participants, writing the UAT scripts, coordinating with our technical teams to stage the UAT environments, facilitating testing, gathering user feedback, and negotiating the resulting changes.
As a product owner, I performed similar tasks, but they happened on an iterative basis at the end of each sprint. I also performed UAT on behalf of my customers from time to time. It all depended on the groups that would be affected by the release and the degree of testing appropriate before a launch."
