If it works small, it might work big. But if it does not work small, it can never, ever work big.
The law has widespread application and speaks to the nature of complex systems. “Scaling” means taking something that is working at small scope, and applying the basic idea to a wider scope. The thing you are trying to scale has to work small before it has any chance of working big. Kanban and Scrum systems are good object examples of tools that work small. Because they work in the small, there is a chance (but not the guarantee) that you can scale them. But before you try, you must confirm that you have it going in the small.
Because if it works small, it might work big. But if it does not work small, it can never, ever work big.
