This document discusses the differences between utilisation and efficiency as metrics for measuring performance.
Utilisation measures the percentage of available hours that a resource spends on assigned work. It indicates how effectively time is being managed to maximize billable hours. Efficiency compares actual output like billable hours to expected output based on hours worked to measure individual performance and return.
While both metrics are concerned with how time is used to contribute to the organization, utilisation focuses on managerial effectiveness in allocating time, while efficiency measures individual performance and productivity levels. The document advocates managing time well to high utilisation targets while maintaining efficient output.
