A specific Agile framework with fixed-length sprints, defined roles (product owner, development team, scrum master), and a set of recurring meetings: planning, daily standup, review, and retrospective.
Scrum gives a team a predictable rhythm and clear decision rights. Its value is less in the ceremonies themselves than in forcing a conversation about priorities and blockers on a regular schedule.
We run a light version: sprint planning, a short daily sync, a demo, and a retrospective. We drop ceremonies that do not earn their time on a given project rather than following the framework for its own sake.
