The difference between actual performance and the relevant plan, budget, or forecast in a given period, expressed in absolute and percentage terms. Variance analysis is the entry-point of finance review and the primary mechanism for surfacing the operational drivers of period results. The federation requires variances above a defined materiality threshold to be attributed to volume, price, or mix drivers, with the attribution documented in the variance log and reviewed at the next operating cadence under UFMS-001:4.1. Repeated unattributed variances signal a planning maturity gap.
From the Latin variantia, difference; the financial sense was crystallised in the standard cost accounting literature of the early twentieth century.
Federation members publish variance analysis with volume, price, and mix attribution above materiality. Repeated unattributed variance is reported as a planning maturity issue under MEV-Annex:5.1. Steward tier accreditation reviews variance methodology consistency.
