Why this matters
Design engineering is not a narrower version of design or a lighter version of engineering. It is ownership across the seams where product quality is usually lost.
Concepts to learn
- Interface craft
- Frontend implementation
- System ownership
- Instrumentation
- Release and repair
Apply It in Casset
Casset is the working environment for this skill—not the curriculum itself.
- Choose one complete feature and own its product decision, interface, runtime, data, release, instrumentation, and recovery path.
- Leave behind code, tests, measurements, and a clear note—rather than a polished surface with invisible debt.
Suggested project
Complete feature ownership
One feature carried from product thesis through production verification and repair.
Evidence of completion
These are completion conditions, not claimed achievements. Each stays planned until it links to a real artifact or verification.

Open questions
- Where does broad ownership create leverage, and where does it need deeper specialists?
- How can one person preserve taste without becoming the only owner?

The goal is not to do every job. It is to understand the whole experience well enough to preserve its point of view.
