Performance benchmarking involves comparing business processes and performance metrics to industry leaders to identify best practices and areas for improvement. It helps companies increase productivity, lower costs, improve quality, and gain competitive advantages. The benchmarking process involves determining weaknesses, forming a benchmarking team, researching potential partners, gathering and analyzing their data, and applying results with or without a third-party consultant. An example is how Dell Computers used benchmarking of other companies to implement just-in-time inventory techniques and online ordering and customization, which provided advantages like reduced costs and increased customer satisfaction.
