The question comes from a service design perspective. I suppose you could look at it in the context of design thinking tools like business model canvas (businessmodelgeneration.com) and customer journey mapping (files.thisisservicedesignthinking.com) which still encourage a linear "inside" and "outside" mindset.

My starting point was that everyone is the user of an organisation (including employees) and that an organisation is not a group of people but a platform to provide experiences for all those who interact with it.

This being the case I was wondering how we evolve design tools to better reflect a conceptual absence of "inside" and "outside".

By the way, liking the look of Branch so far. :)

Thanks Simon. I'm foreign to the field and I'll take a look :)
