While building Axolo we are talking to CTO and developers. Some of the things I learned that were super interesting:
Polaris Methodology:
One CTO told me this one: They have 6 weeks sprint (Q&A included) + 2 weeks of rest. The rest is a time for them to go back to what hasn't been completely finished 'smelling code' he calls it. Those two weeks is an opportunity for them to refactor and rethink their architecture.
