Benchmarking is defined as a process of improving performance by identifying best practices inside and outside a company and implementing results. The main advantages are product and process improvement through imitation rather than invention, which reduces time and costs. There are different types of benchmarking including strategic, performance, process, functional, internal, external, and international benchmarking. Successful benchmarking requires management commitment, resources, proper infrastructure, and following best practices such as involving employees and relating improvement to strategy. Limitations include being time consuming and expensive, with difficulties in information sharing due to perceived differences between organizations.
