Why Product Owners should challenge technical solutions

When I started out as a Product Owner I never challenged my teams on the technical solution. I believed it was not my job to do so.

As I gained more experience and technical understanding, my opinion changed. I now do think it is my job to challenge them on the technical solution. Allow me to give a concrete example.

At refinement we discussed a new epic. I explained the why, the business value and what we wanted to achieve. It was something that needed to run just once per day.
