                 Active and Passive Metrics and Methods
                     (with Hybrid Types In-Between)

Abstract

   This memo provides clear definitions for Active and Passive
   performance assessment.  The construction of Metrics and Methods can
   be described as either "Active" or "Passive".  Some methods may use a
   subset of both Active and Passive attributes, and we refer to these
   as "Hybrid Methods".  This memo also describes multiple dimensions to
   help evaluate new methods as they emerge.
