Principles04 — Operating Notes
01

Reliability is an engineering discipline

Built into the system from day one. Not bolted on after the first incident.

02

Craft is non-negotiable

User experience is engineering. The seam between the two is where most products fail.

03

Architecture is a long game

The right call this quarter is the one that holds up three years from now.

04

Write the post-mortem first

If a system can fail in a way you cannot describe, it is not yet ready to ship.
