6 Principles for Product-Grade System Design
A practical framework for designing systems that scale in both product behavior and engineering operations.
Why I Start with System Boundaries
Before building UI, I define product boundaries:
- What state is authoritative?
- Which path is latency-critical?
- Where does consistency matter more than speed?
Without these constraints, interface decisions become expensive rewrites.
Flow is the Product
A page is not the product.
The sequence between pages is.
I optimize transitions, not isolated screens:
- Entry intent
- Decision point
- Commitment action
- Recovery path
Delivery is Part of Design
Design that cannot be released safely is unfinished.
deploy pipeline = design system + validation system
Every change should be traceable from intent to production behavior.
