System re-engineering of the Italian Tax Documentation Service smoothly progressed through a phased set of stages:• Definition and refinement of key end-user-profiles through observational and contextual analysis• Previous version in-depth screening through focused usability-lab tests• Interface and interaction design through mock-up screen-shots and interaction graphs• Early prototype construction• Newer and older versions usability-lab pair-wise comparisonThe project served as a test-bed for the Esprit n.20857 Project MAPI (MUSiC Assisted Process Improvement) aimed at engineering usability evaluation and metrics methods and tools, as part of the MUSiC (Measuring Usability in Context) method and toolset. The industrial experience which is reported in this paper, shows that a challenge for the future resides in understanding and modeling how to re-engineer legacy systems and turn the "legacy software life cycle" into a new "user-oriented software life cycle", based on prototyping, early evaluation and metrics collection within a cost-justifying usability approach.
