Apdex

Reducing measurement data to a single well understood metric is a convenient way to track and report on quality of experience.

Measurements of application response times, in particular, may be difficult to evaluate because: The Apdex method seeks to address these problems.

The resulting Apdex score is a numerical measure of user satisfaction with the performance of enterprise applications.

The Apdex Alliance, headquartered in Charlottesville, Virginia, was founded in 2004 by Peter Sevcik, President of NetForecast, Inc.

While the number of contributing companies has remained relatively stable, individual membership grew to over 800 by December 2008, and reached 2000 in 2010.
