Agile teams must embrace change. After all, that is what agile means, right? Accommodating changing customer's requirement… But the stakeholders or customers must also understand that nothing comes for free in the world. So are changes. They have a cost related to them. Scrum works on a rule that once the required changes are fully stated, a sprint begins. And no changes are allowed into a sprint. Once a sprint is started, it’s not disturbed and the team’s entire focus is on selected work. This is good and works efficiently, but can sometimes backfire. The customer can question that the foundation of being agile is to welcome changing requirements. Well, yes, but they aren’t free.
