Meet the Chen family
Two kids. Bus at 7:35. Mom used to write the same checklist on a whiteboard every night. The problem was the whiteboard never changed, even when the bus time did, or when one kid had an early band practice.
With a launch sequence, the Chens enter their actual times. The chart shows that Maya starts breakfast at 6:50 while Leo is still getting dressed. At 7:10 they swap. By 7:25 both are packing up. Mom can see the whole morning at a glance.
