FEDERAL ENTERPRISE ARCHITECTURE (FEA)
➤ Example
Homer: Do you have a torch I can borrow?
Peter: No, I'm afraid not.
Homer: Do you know where I can get one?
Peter: The hardware store in town should have one.
So, Homer goes out to the hardware store and buys himself a torch.
He returns.
Peter: Did you get your torch?
Homer: Yes, here it is.
Peter: That's not a torch! That's a flashlight. Why didn't you say so?
I have one you could have borrowed.
Homer: Well, why didn't you say so?

HOW TO?
➤ The ability to reuse relies in an essential way on the ability to
build larger things from smaller parts, and being able to
identify commonalities among those parts (wikipedia).

SOLUTION
➤ No single solution
➤ Generic, Stability, Modularity, Extensibility
➤ Orthogonality in design and architecture
➤ Best practices should become procedures
➤ Responsibilities to right people
➤ Incentives on reusable modules
