The best architectures rarely collapse overnight.
They erode slowly one exception at a time.

Architecture drift is that silent killer that transforms an elegant design into an unmanageable tangle often before anyone even notices. After years of working with systems that slowly veered off course, I’ve developed a practical checklist to catch drift before it becomes a crisis. 🔍

✅ Watch for “just this once” exceptions.
When teams repeatedly bypass established patterns for short term gains, it's a major red flag. I conduct regular architecture reviews not just to assess new features, but to detect pattern violations. A lightweight exception approval process has helped reduce architectural debt significantly.

✅ Mind the documentation gap.
If the system’s actual behavior consistently diverges from its documented design, you’re already drifting. I maintain living architecture documents and reconcile them regularly with real implementations this simple habit has surfaced many issues early.

✅ Close cross team knowledge gaps.
Architecture drift accelerates when key principles are known only to a few. We’ve addressed this by building communities of practice and holding regular knowledge sharing sessions across engineering teams.

🔄 Not all drift is bad.
Sometimes what looks like drift is simply your architecture adapting to evolving business needs. In these cases, the right move isn’t enforcement it’s realignment. Let your design principles evolve when the context demands it.

What early signs of architecture drift have you seen in your systems?
How do you course correct before it’s too late?
