This document is intended to be a guide for the use of the Reusability Quick Assessment Toolkit (RQAT) by the Solution Owners of any organisation (both European Commission and Public Administration / Institution at European, National and Local level) who decide to assess the Reusability (RES) of their software solution.

The Reusability Quick Assessment Toolkit, developed in the context of the Action “Assessment of Trans-European solutions supporting EU policies” of the ISA2 Programme, is based on explicitly differentiating between Application Components and Application Services.
