Each control in Acuna displays a colour-coded health badge — green (healthy), orange (at risk), or red (unhealthy). Health is driven primarily by recurring task completion: a task completed on time scores as healthy (100), completed late scores as at risk (75), in progress but not past due as at risk (75), and not started past due as unhealthy (0). These scores cascade upward through measures and requirements so operational slippage surfaces in the control and programme views, not only in a task list. Click any health badge for a breakdown explaining which tasks contributed to the current score.
