Core Principles
The Learning Cadence Sets the Pace
Loop length emerges from how fast you can close a learning loop, not from a calendar.
In Scrum, the sprint length is fixed (two weeks). In Shape Up, the cycle is fixed (six weeks). In LDD, the natural unit of time emerges from how fast you can close a learning loop, not from arbitrary calendar divisions.
Some learning loops close in a day. Some take a week. The approach should support variable loop lengths, with natural breakpoints for synchronization and decision-making, whether that's a team standup or a solo builder's weekly reflection.
