My contract manufacturing company does this. Our standard contract has a 5% bonus for being less than 10% late on the delivery date (and penalties start around 25% late). After suppliers see the contract they will often revise their originally quoted schedule.

The predominant domain to use this type of contract is infrastructure construction. I haven’t personally seen it used in software development outside of control systems but I can’t immediately think of reasons why it couldn’t be extended to other domains as well
