We can illustrate a violation of this pattern with an example of two modules: Order and User, where Order’s facade exposes a lot of methods like GetProduct(), GetTax(), GetAvailability(), SetBasket(), SaveOrder(). Whereas the User module invokes all these methods (in the correct order!). As you can see, the communication is very intense and the User module is the coordinator to something that looks like a “CRUD” Order module. To reduce coupling we could move the coordination logic to the Order module itself and just expose one PlaceOrder() method.
