NOTE 01
What to verify before using AI in a product
Define the inputs and evaluation criteria first. The design must also account for cost, latency and failure.
ENGINEERING NOTES
Questions to answer before implementation
Choosing technology is only the beginning. These notes examine the decisions that shape how a product behaves in use and how it can change over time.

NOTE 02
When to rebuild and when to repair
How to decide what should stay and what should change without losing data relationships or operating knowledge.

NOTE 03
Permissions and state before the interface
Why access rules and data state need a recovery path before the interface is refined.
Four questions before design begins
- BOUNDARY
- How much should the system be allowed to do?
- STATE
- What state are the data and request in now?
- FAILURE
- What remains after a partial failure?
- RECOVERY
- Who may reverse the action and what record do they need?
