Everything is scheduled in whole weeks. Every task lands inside one week, so the Monday status note always has a clean "last week / this week" to report. This is the ideal-scenario plan — five phases, each with its own sub-phases and approval gates.
No task crosses a week boundary. If something takes two weeks it appears as two weekly items, so the Monday note always reports a finished thing.
Client review weeks are real weeks on the plan. A gate that runs long pushes launch one-for-one — the work behind it cannot start early.
Design happens in the build, so changing direction after the lock means rebuilding rather than redrawing. On Extra Large it locks every release at once.
Discovery, direction and the catalog are paid for once, then every release inherits them. Two Mediums as one programme beats two Medium projects.
