Scrum embeds three inspect-and-adapt loops: daily standup (1-day cycle), sprint review (1-4 week cycle for the product), and retrospective (1-4 week cycle for the process). — Scrum.org

OKR (Objectives and Key Results) The user's xettel frames this as a thermostat that checks once a season — functional, but slow. Compared to Scrum (sprint-length loops) or Kanban (continuous flow), OKR operates at the lowest frequency in the management feedback spectrum. →

Open-Loop vs Closed-Loop Systems Goal-setting frameworks vary in loop frequency: OKR checks quarterly (xettel), Scrum inspects every sprint (xettel), Kanban operates as continuous flow (xettel). A quarterly OKR is effectively a thermostat that reads the thermometer once a season. →
