This module focuses on where architecture work should happen and how changes should mature before production.

Learning objective

Use dev for experimentation, use test for preparation and review, and treat production as the place for proven configuration.

What to learn

• why dev is a sandbox;
• why test is the preparation surface for promotable configuration;
• why production should not be the first learning surface;
• how to classify a change as experiment, candidate configuration, or production-ready.

Exercises

1. List three changes that belong in dev first.
2. List three changes that should be reviewed in test before production.
3. Explain one scenario that should never be learned first in production.

Completion signal

The learner stops treating promotion as a copy step and starts treating it as a governance decision.
