Planning Makes Perfect is an in-game achievement in Run 3.
To earn this achievement, use either the Skater or the Child (although, the Skater is a bit better), and move right at the start to cross the first gap. After that, you can get into the air by using ramps and/or landing on the sides of boxes. The Skater benefits more from ramps, and the Child benefits more from boxes.
Walkthrough 1: here.

If you need to see if the achievement is completed or not, look in the achievement menu to see if it is completed.
