Architecture decays unless guided
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
explain why good architecture erodes without active guidance, and what guidance looks like.
Planned topics
- Decay is the sum of many reasonable local decisions: a shortcut, a copied client, an unowned dependency.
- Reviews catch decay late and do not scale to 25 teams.
- Guidance means writing down what must stay true and checking it automatically.
- Decay also comes from outside: versions age, vendors change, traffic shapes shift.
Draft outline details
Demonstration
a chart idea for Commerce 2030: count of cross-domain imports per quarter, rising steadily, with the one incident it later caused marked on the line.
Check your understanding
Why do reviews alone fail to stop architectural decay at 25 teams?
Show answer
They are manual and late; they cannot see every change across every team.
