• Models and Metaphors - One of us (Mathias) consulted for a client that acted as a broker for paying copyright holders for the use of their content. To do this, they figured out who the copyright holders of a work were. Then they tracked usage claims, calculated the amounts owed, collected the money, and made the payments. Understanding who owned what was one of the trickier parts of their business. — “It’s just a technical problem. ” — “But nobody really understands how it works!” — “Some of us understand most of it.

• Use a general purpose language to manage the interface evolution - Many commercial integration tools market their ability to own the integration landscape and call out to general purpose languages as needed. While Brandon can appreciate the marketing behind such messaging — it promotes product penetration and lock-in — as architectural guidance, it is exactly backwards. Instead, we should almost always manage the interface evolution in a general purpose language for at least two reasons: so we can better manage the complexity of maintaining a clean interface, and so that we avoid the gravitational pull of our tool's mental model when making strategic integration decisions. more… [Martin Fowler]
