No process is immune from the need to be redesigned. This is inherent to the life cycle of every process. The trick is to redesign it before our well loved but clunky processes make your company lose business and value. To some this suggests benchmarking as a cure. This is where processes are isolated from their system in the hope that using a benchmark for a process, with the same name, from a foreign system will somehow spur or shame us into better performance.
Many intermediaries exist to sell benchmarks and even the processes that belong to other companies.
Yes, such practice is also ineffective. To stay in business we have no option but to renew objectives and redesign our processes. This is the other reason for developing and using our system.
