# Data, not intuition, should guide scheduling

The core philosophical shift of the source: replace intuition-based rules of thumb with localized measurement. The two rules of thumb it names — "more notice is good" and "denying change requests is bad" — are precisely the ones the contrarian findings [[contrarian-predictability-not-absolute]] and [[contrarian-managerial-flexibility-nuance]] overturn. It underwrites [[claim-uniform-policies-fail]] and the measurement layer of the [[concept-scheduling-quality-dimensions|five dimensions]].
