Maker vs Manager Schedule

Definitions

Paul Graham's observation that makers (programmers, writers) need long uninterrupted blocks (half-days minimum) for productive work, while managers work in one-hour appointment slots. A single meeting in the middle of an afternoon can ruin a maker's entire half-day. Organizations must protect maker time by clustering meetings and establishing no-meeting days.
In plain English: The idea that programmers need long uninterrupted blocks to be productive, while managers work in short meeting slots.
Example: "We have no-meeting Tuesdays and Thursdays — the maker schedule gives engineers 8 hours of uninterrupted focus time per week."
