Cooking several components for dinner without everything finishing at different times

Dinner is chicken thighs, roasted vegetables and rice. Every part takes a different amount of time, so one thing always sits getting cold while another finishes. I'm finally trying to plan backward from when we want to eat: oven on first, vegetables prepped, rice started later, meat rested briefly. How do home cooks coordinate a three-part meal without turning the kitchen into a restaurant service? My biggest problem is remembering the resting time.
