Everyone sees their own tasks and deadlines; you only see the exceptions. Reminding is one click, not an email round.
The chasing usually exists because nobody knows exactly what is expected of them — except you, in a spreadsheet. In Oanax everyone has their own task list: what is open, what is coming, what is overdue. Overdue work sits on top.
You watch the exceptions view: who is behind, where things stall. Reminders go out with one click from the system.
The relationship flips: people see for themselves what is going on, and you only step in where attention is needed.
