NOTES / 01
The value of a short checklist
A checklist is most useful when it captures the things that are easy to forget, not everything that could possibly be done.
Keep the list near the task, make each item observable, and revise it when a surprising failure teaches you something.
NOTES / 02
Measure the path, not only the destination
When a system feels slow, start with a small measurement that can be repeated. Record where it was taken and what changed.
A single successful test is a useful observation, but several observations over time tell a more reliable story.
