Tally every physical reach and digital tool switch for one…

For one full work session, keep a tally sheet and mark every time you reach for a physical object or switch to a digital tool — do not trust intuition about usage frequency, as it is systematically biased toward what feels important rather than what is actually frequent.

When This Fires

Before reorganizing any workspace (physical or digital)
When workspace organization "feels right" but doesn't seem to reduce friction
When Three spatial zones by usage frequency's zone assignments need empirical grounding
Complements Measure actual elapsed time over 3-4 cycles before… (measure before optimizing) applied to workspace layout

Common Failure Mode

Intuition-based organization: placing items where they "should" go based on perceived importance rather than measured frequency. The result is a workspace optimized for the wrong interactions — high-importance but low-frequency items in prime positions while high-frequency but low-salience items are buried.

The Protocol

(1) Keep a tally sheet next to your workspace (paper or quick-capture app). (2) For one full work session (2-4 hours), mark every time you: reach for a physical object, switch to a different digital tool/window, open a drawer or folder, or move away from your primary position. (3) For each mark, note what you reached for or switched to. (4) At the end, count: rank items by frequency. (5) Compare the ranking to your intuitive sense of "what I use most." The discrepancies are the optimization opportunities: high-frequency items should be in the active zone (Three spatial zones by usage frequency); items you thought were high-frequency but aren't should move further away.
