With the increasing use of micro-controllers in smart~instruments and control~systems,
software is increasingly being seen as the `missing~factor' in FMEA analysis.

This paper presents a new modular variant of FMEA, Failure Mode Modular Decomposition (FMMD).

Because FMMD is modular and hierarchical, and deals with all its objects in terms of their failure mode behaviour,
it is ideally suited to creating integrated software and hardware models.

This paper takes a simple example of a hardware/software hybrid (an industry standard {\ft} input), analyses
the hardware and software using FMMD, and then discusses the effectiveness of the
failure modelling from the perspective of the hybrid hardware/software sub-system.
