configuration management

   administrative controls to identifying, documentating and
   reporting on configuration items, their physical and functional
   characteristics and changes to characteristics of those
   configuration items.

   Change management is one aspect of configuration management but
   may also refer to the softer, human side of getting people to
   adapt to changing processes and organisation.

   management applied to code through the various stages of the
   software life-cycle.
