A fault isolation and test (FIT) subsystem for a hardware suite: a systems engineering case study

This work covers how the systems engineering approach to problem solving was applied to the FIT (fault isolation and test) subsystem as it was developed and tested. FIT´s underlying requirements and goals are reviewed. Several characteristics of the problem that FIT was built to solve required a highly integrated product between the three main components of the operative system: the user, the software, and the hardware. A general methodology for building FIT is proposed, using the systems engineering approach to problem solving as the framework
