Systems don't announce their problems. Learn to read the warning signs before it's too late.

Symptoms of a failing system

  • Simple changes take weeks
  • Only one person understands how it works
  • New features break existing functionality
  • Performance degrades over time
  • Workarounds outnumber features

The accumulation problem

Technical debt is like financial debt. Small compromises compound until they become unmanageable.

When to restructure

The best time was before the problems started. The second best time is now.

Restructuring vs. rebuilding

Not every system needs to be rebuilt from scratch. Sometimes targeted restructuring is more effective and less risky.

Conclusion

Ignoring system health doesn't make problems disappear. It makes them more expensive to solve.
