ICO Std 2002 is the world's first universal standard covering the full lifecycle of ranking methodology — principles, indicator design, weighting, data collection, scoring, publication and audit. It works in concert with ICO Std 2001 (DPP-CQ): Std 2001 governs data inputs, Std 2002 governs methodological integrity.
