1. A design failure mode effect analysis (DFMEA) method of analyzing faults and failures in the design of electronic apparatus and devices, wherein an information recording form including a data-entry mask is used for recording some information concerning the performed analysis and in which at least a portion of said recording form is displayed to a user in an electronic display format;

  • the method comprising;

    detecting and recording past design problems and corresponding solutions to the past design problems using said recording form;

    associating keywords in a database to each said past design problems as individual functions;

    associating data concerning each of said past design problems, in the same database, including information concerning past fails that occurred in similar applications;

    detecting major changes and/or innovations, as well as any improved block or part of a new device with respect to other devices, thereby postulating possible new problems introduced by the new device; and
