What design is for people, architecture is for systems. It needs to be clear to be understood by both people and systems. Architecture is back-end design, as I state it, and there are so many flavors: Infrastructure, Enterprise, Reference, Integration, Frontend, … It is very important to make sure the set you use are all aligned and pinned on the same business goals and strategic choices. Therefore, I create a strategic linked architecture to tie the technical components to the business direction and strategy.
