90 Day Sprint

Ninety days of concentrated work toward one named outcome — the operational unit of a season, and the older name for what the Game now keeps by the sun.

A sprint is a bounded run: a fixed length, one aim, a team that stays together for it, and a hard stop at the end where what happened is counted rather than extended. Ninety days is chosen because it is the natural unit of transformation — long enough to accomplish something real, short enough to keep urgency and focus, and short enough that a person can hold the whole of it in mind from the first day.

It is load-bearing because it makes work finishable. Effort that runs continuously is never assessable; effort in ninety-day runs is assessed four times a year, whether or not anyone feels like assessing it. The stop is the point. It is also the interval at which a plan can honestly be re-pulled: what was assumed three months ago has moved, and a body that re-plans at a fixed rhythm is far less likely to be carrying a plan it no longer believes.

In the Game, the sprint and the Season are the same ninety days approached from two directions, and the difference matters. A sprint is bounded by a start date someone chose; a season is bounded by the sky, at turnings no one owns, and is named by the turning that opens it rather than by a project. The practical consequence is that every Circle on Earth starts and finishes together, which no sprint calendar can deliver. A sprint ends; seasons return.

In the System, the sprint vocabulary survives where a specific push is wanted inside or across seasons — the forty-two-day launch sprint that a first season may use to stand a body up is a worked example of the shorter form. The discipline is the same in either case: one aim, constraint-free work released, the kept-as-a-share-of-made counted at the end, and the stop honoured.
