Benchmarking is the process of measuring an organization's internal processes and comparing them to industry best practices in order to identify areas for improvement. It involves measuring performance using metrics, understanding differences in processes between companies, comparing to external competitors, and imitating and adapting superior practices from industry leaders. The key steps are planning what to benchmark, collecting data, analyzing performance gaps, and improving practices. Benchmarking provides a way for organizations to continuously learn and improve without having to reinvent processes. It is important for survival and helps drive improvements in performance.
