impactvol

Impactvol is a term used in impact investing and program evaluation to describe a framework or measurement approach that combines the scale of social impact with its measurement stability over time. It intends to capture both the magnitude of outcomes and the consistency of those outcomes across different periods or populations.

Origins and usage: The term originated in professional discourse in the 2010s but has no formal standard definition. It is often used informally to refer to dashboards or metrics that adjust impact scores by volatility, akin to risk-adjusted return in finance. Practitioners may implement impactvol through composite indices or scorecards that weight qualitative and quantitative indicators.

Methodology: An impactvol assessment typically aggregates multiple indicators such as reach, depth of impact, longevity, and cost-effectiveness, then applies a volatility adjustment to reflect outcome variability due to external factors. Results may be presented as a single score or a dashboard that highlights high-impact, high-variability areas requiring risk mitigation or adaptive programming.

Evaluation and critique: Proponents claim impactvol supports better portfolio construction and resource allocation by emphasizing durability of outcomes. Critics note a lack of standardized definitions and data challenges, risking oversimplification or misinterpretation if volatility adjustments obscure underlying drivers. As with other impact frameworks, it is most effective when paired with transparent data collection and governance.
