Doelranges

Doelranges, or target ranges, refer to a predefined interval around an objective value within which performance is considered acceptable. The interval is defined by a lower bound and an upper bound; often a central target value exists inside to guide interpretation. The purpose is to guide decisions, monitor performance, and manage risk by signaling when actions are required or when outcomes are satisfactory.

Doelranges are used across multiple domains. In macroeconomics and finance, authorities may establish an inflation or growth range to accompany a target value; in business, teams use ranges for revenue, costs, or service levels; in quality management and healthcare, ranges trigger checks or interventions when measurements fall outside these bounds.

Ranges can be fixed or dynamic, and they are typically set by a governing body or management, based on historical data, forecasting, risk tolerance, and scenario analysis. They may be revised in response to new information or changing objectives.

Advantages include clearer accountability, predefined decision rules, and a structured response to deviations. Limitations include the risk of overreliance on a single metric, potential rigidity, measurement lags, and the need to regularly reevaluate ranges to remain relevant.

Examples: a central bank might target 2% inflation with a tolerance band of ±1 percentage point; a company might aim for 95% on-time delivery with a 90–98% range. In Dutch usage, doelrange is the common term for this concept; in English contexts, target range or tolerance band is used.
