Benchmarking is the process of measuring an organization's internal processes against industry best practices to identify areas for improvement. It involves understanding current performance levels, planning benchmarking studies, collecting data on best-in-class competitors, analyzing performance gaps, and implementing findings to close those gaps. There are three main types of benchmarking: internal, competitive against close rivals, and generic/functional benchmarking across different industries. Benchmarking helps organizations set targets, prioritize resources, and continuously improve processes to reach world-class performance levels.
