You can achieve operational excellence through process, but craft can only be achieved with tenure.
During his conversation with Patrick Collison, Jensen argued that although operational excellence can achieve many valuable things, exceptional outcomes require something more nuanced, like craft.
What makes the difference is that operational excellence can be systematized through processes, while achieving exceptional craft requires the experience and accumulated knowledge that come with tenure.
Craft is impossible to codify into a set of explicit instructions. It can only be developed over time by a team that has shared experiences and has collectively learned to operate on a deeper, almost intangible level.
