What is Scrum Team Velocity?
This is a tricky one, and you need to be answering it in the context of the organization you are interviewing with and its complementary practices.
Let’s start with the basics. Velocity is mentioned quite a few times in connection with Scrum in various contexts. First thing you might hear is that the velocity is a measure of the team’s ability to deliver value to the customer. That’s quite an okay definition you might give to your interviewer. Just be ready for an onslaught of questions it might bring, such as, “What do we measure”, “How do we measure it”, “Why do we measure it”.
Velocity is recognized by Scrum.org as a complementary practice. This means, that Scrum framework does not have a prescription for a Scrum Team as to how to measure its ability to deliver value. Remember that Scrum is a framework, which can work really well with a variety of practices that fit teams needs, desires, and abilities. And velocity is one of such practices.
