I recently helped a Protime (https://www.protime.eu/) with a transformation from feature teams to stream aligned teams - or how we called them: domain teams.
In this case study, I'll go over what went wrong with their past setup, what kind of problems we've solved and what challenges are still open.
I'll talk about changing the team structure (from mostly dev teams to more cross functional teams) and giving teams more autonomy, clear ownership and responsibilities helps the teams grow and improves flow in the company.
