Still Doing Architecture Principles

Most EA principles sound good but do not change a single decision because they are not testable.

Now you can wire that into governance (architecture reviews, portfolio decisions, roadmaps) and report progress quarterly. At that point, it stops being a poster on the wall and becomes a scoreboard the business can hold EA accountable to.  Let us explain why Architecture Principles faded away in the 1990's - let us not go backwards in time.
