The HR operating year
Answer a few questions about your company. This places every program on the year by its live window and the prep nobody plans for, then shows the two things a checklist cannot: the months where everything lands at once, and what depends on what. Nothing you enter leaves this page.
Add anything the defaults miss, and it lands on the wheel immediately. A second engagement survey, each country's benefits renewal, an off-cycle promotion round, a board deadline. These are yours; a small ring marks them.
Every program, in order, with the prep-start date people forget and the handoffs that break when the timing is wrong.
