Integrated systems health management (ISHM) is one of several approaches to building automated diagnostic and prognostic systems. We describe a unique architecture for ISHM along with other key technology elements such as Smart Sensors complying with the IEEE 1451.x family of standards, and user interaction methods. Technology readiness levels (TRL) and functional capability levels (FCL) are useful metrics for evaluating the readiness of each contributing technology and identifying those technologies that need further development. ©2008 IEEE.
