Dave and Jamison answer these questions:

I’m a front-end web developer on a SCRUM team. Our Product Owner is also our tester, but she has a very busy schedule and she hardly has any time to test anymore.

My team thinks we need a second product owner, but I think we should hire a dedicated tester to help the PO. How do I convince my team and my manager to hire a tester instead of a second product owner?

We don’t work with scripted test plans or anything, so I think a dedicated tester would be a huge benefit to our team and our deliverables.
