Okay kiddo, imagine you have lots of toys to play with, but you can only play with one at a time. Sometimes your friends might also want to play with your toys, but you don't want them to take all of them at once because then you won't have any left to play with.
A resource ordering status system is like a system that helps you keep track of which toys your friends want to borrow and when they can borrow them.
Let's say your friend Timmy wants to borrow your toy truck tomorrow, but your other friend Sally wants to borrow it on the same day too. You don't want to disappoint either of them, so you use the resource ordering status system to keep track of who gets to borrow the truck first.
You write down Timmy's name on a piece of paper and mark it as "reserved" for tomorrow. Then you write Sally's name under Timmy's and mark it as "waitlisted". This means that Timmy gets to borrow the truck first, and Sally will have to wait until Timmy is done playing with it before she can borrow it.
This is like how a company might use a resource ordering status system to keep track of who gets to use certain resources (like equipment or meeting rooms) when. It helps them avoid conflicts and ensures that everyone gets a fair chance to use the resources they need.
