The ReverseAndReengineeringTaxonomy defines reverse engineering as:

The process of analyzing a subject system with two goals in mind:

  1. to identify the system's components and their interrelationships; and,
  2. to create representations of the system in another form or at a higher level of abstraction.

Observe that reverse engineering is a process of examination only: the software system under consideration is not modified (which would make it ReEngineering).
