Question: Who is doing FAST today?
Answer : Spotify, Valve and GitHub are doing aspects of FAST
Spotify : I was excited to read that my idea of a tribe and the max size of a tribe being Dunbar's number match the model described by Spotify. The Spotify tribe are all co-located and work on the same project. FAST differs to the Spotify tribe in that FAST lets the tribe self-organize into teams where Spotify has a notion of fixed squads.
Spotify is a company that created a music platform by the same name and have become famous for their agile process as well as their world-class service/product.
Valve : Valve allows teams to self-organize and self-manage.
