Principles that decide things
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
write principles that settle real disagreements.
Planned topics
- A good principle has a trade-off built in: "prefer X over Y even when Y is faster".
- Test: could a reasonable team choose the opposite? If not, it is a platitude.
- Attach a short example and the reason for each principle.
- Keep the list to under ten; revisit when disagreements recur.
Draft outline details
Demonstration
two principle versions: vague ("build scalable systems") versus decisive ("prefer asynchronous events between domains over synchronous calls, except for user-facing reads").
Check your understanding

Show answer
It shows a real trade-off and makes the principle usable in a dispute.
