Variance commentary
Variance commentary is the written explanation accompanying variances in management or board reporting. For variance commentary, the useful boundary is the driver, assumption, source data, owner, time period, scenario logic, and decision the model is meant to support. For variance commentary, the practical standard is making the driver, assumption, and owner visible when actuals change.
Also known as variance narrative, management commentary, variance explanation
Why it matters
Understanding variance commentary matters because planning only improves decisions when assumptions, drivers, owners, and time periods are explicit enough to revisit when actuals arrive. Pluvo drafts variance commentary from the computed root cause, so the narrative is grounded in traced drivers rather than written from guesswork.
In practice
Planning example
Teams use variance commentary when a forecast, budget, or scenario needs an assumption that can be revisited. The finance team should know the driver, source data, owner, and period before using it in a model.
Pluvo example
Pluvo drafts variance commentary from the computed root cause, so the narrative is grounded in traced drivers rather than written from guesswork.
In practice, teams should define variance commentary with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for variance commentary separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.
