What is a job title that conveys the duties of the manager of a product team that is striving to be Agile, that is meaningful in the broader market and would convey that person's value both outside and inside the company?
The product team's members would report to this person; this person is dedicated to their team and will facilitate any organization-related needs for the team. They are a leader and a liaison to senior managers and the broader organization, but they are not the Product Owner. This person wouldn't necessarily help to build the product, though they could if they want. If the team is running Scrum, this person would only serve as Scrum Master if the team determined they were the best to serve as such.
So what title would you give this person?
