I became the scrum master of a newly established team, that is responsible for creating a software AND maintaining other deployed application. So basically each team member has development & operations tasks.
I have been observing how they work the past couple of weeks and I noticed that team is having troubles in coordinating these tasks. when a developer is concentrating on coding he get interrupted to fix an issue raised in production, and it's hard for him to focus again on previous task.
I have tried allocating % of developer time for operations work but apparently this isn't resolving the issue. I'm interested in hearing from scrum masters who came across this situation before, how did you manage it and what are your recommendations?
