Github is a very special case because they have a relatively simple product and very tech savy audience. I currently work on a very large b2b web platform/application where customers are typically 40+ and still using Internet Explorer. Its also so massively complex that you just cant do it without extensive planning and talking about every last detail of the implementation with all people involved. I wanted to avoid it, but not talking things through in detail usually results in misunderstandings and more work down the line.

Its great that github can do it like this and i envy them for it, but its not a one-size-fits-all solution to project management
