Diagnostic Tool

Revenue Diversification Index

This diagnostic measures how evenly revenue is distributed across the different activities, products, services, or markets that the business operates in. It generates a diversification score that reflects whether the business operates with a broad, resilient revenue base or whether it is heavily dependent on a narrow set of income sources.

In practice, revenue concentration by segment often mirrors customer concentration but operates through a different mechanism. A business may serve many customers but generate most of its income from one product category, one geography, or one service line. If that segment is disrupted (by substitution, by regulatory change, or by competitive pressure), the entire revenue base is exposed even if the customer list appears diversified.

Understanding diversification matters because it determines the resilience of the revenue engine to changes in specific segments. A highly diversified revenue base absorbs segment-level disruption without a structural crisis, while a concentrated base transmits the full impact of any single-segment disruption directly to the profit and loss account.
