I've had discussions with other programmers on interfaces (C#). I tried to use the analogy of interfaces being like a contract between programmers. Meaning that when you design to an interface, you are designing to a "thought out plan".

This didn't fly. The other programmers (limited experience) couldn't get the concept. Or worse, refused to participate.

How do you explain to people like that there are reasons to use interfaces?

Thanks
