To obtain valid and reliable results, the people observed should be representative users performing representative work tasks in appropriate circumstrmees, and the analysis should be methodical. The MUSiC Performance Measurement Method (PMM) - developed at NPL as part of the ESPRIT Project MUSiC: Metrics for Usability Standards in Computing “ provides a validated method for making and analysing such video recordings to derive performance-based usability metrics. PMM is supported by the DRUM software tool which greatly speeds up anrdysis of video, and helps manage evaluations. USABILITY AND CONTEXT Usability can be defined in terms of the efficiency and satisfaction with which specifkxl users ean achieve specifkd work goals in given environments. The MUSiC Context Guidelines Handbook provides a structured method for identifying and describing key characteristics of the ˜context
