Amber at the Fixed Point

A Renormalisation-Group Account of KPI Roll-Up in Business-Intelligence Hierarchies

A research poster from the School of Emergent Priorities treats each tier of a business-intelligence reporting hierarchy as a block-spin transformation and measures scaling eigenvalues for twelve indicator families across five roll-up levels in 23 organisations. Summed indicators are relevant, averaged ones irrelevant and worst-of statuses marginal, and a RAG status rolled up by worst case with escalation flows to a stable fixed point at amber, so that executive tiers fall into one universality class per aggregation rule.
