Three articles independently overturn the same instinct: that a single, centrally-set rule can be applied uniformly across a distributed system.

- **A111**: [[claim-uniform-policies-fail|uniform scheduling policies don't deliver uniform results]] — the same 12-day notice window yields 4% turnover at one retailer and 8% at another. Drivers vary by [[claim-store-format-differences|store format]], [[claim-worker-segment-differences|worker segment]], and [[claim-regional-labor-markets-dictate|region]].
- **A115**: the blanket radius is [[contrarian-radius-inefficiency|wasteful]]; effectiveness depends on [[concept-relative-proximity|who's closer than the rival]] and forms a [[concept-inverted-u-shape|donut]], varying by campaign type and geography.
- **A108**: strategy dictated from HQ ignores local expertise; [[action-require-regional-briefs|framing must originate at the periphery]].

**The shared prescription** is a continuous, localized *experiment* rather than a static policy — A111 literally calls scheduling a "[[quote-living-experiment|living experiment]]". The boundary condition, honestly flagged in all three, is that hyper-localization can create cross-location inequity and coordination cost — which is exactly why A105's [[concept-structured-empowerment|curated options]] and A108's [[claim-centralized-control-still-necessary|retained central control]] act as guardrails. See [[cross-where-and-how-decisions-begin]] and [[cross-data-foundation-prerequisite]].
