Customer Perceived Latency (CPL) is a new term for a simple, established idea: measuring latency from the callerís perspective. It can be a very powerful tool in creating and maintaining voice self-service applications. Customer satisfaction and the customer quality of experience are critical to an organizationís success, and latency is an important element of usability and of the customer experience.


CPL can and should be used throughout the application delivery process: from design, through system test and deployment, to production monitoring. Measurements are done from outside the system, ideally across the same networks customers use. Products and services are available to make CPL measurements simple, non-intrusive and cost-effective.
