We are not purists at LinearB. Certainly not when it comes to "methodologies" like Agile or Scrum. We're not bothered with how things are "supposed" to be done. All of those rules are just dogma to us and we don't care.
We believe in lean engineering and we buy-in to a lot of ideas from the Agile Manifesto. But some Agile principles are outdated. Like "The most efficient and effective method of conveying information to and within a development team is face-to-face conversation." Not for us. We embrace asynchronous as the default form of communication within our dev team.
