The FRAM Model Visualiser



Extending the capabilities of the FMV

There is an increasing interest in utilising the FRAM approach for the analysis of what exactly is going on in complex sociotechnical systems in practical high hazard environments. There are, for example, a number of ongoing projects at the moment in aviation, self-driving vehicles and, of course, on the challenges of the COVID 19 pandemic for healthcare responses. But as well as these practical applications there is an increasing interest from the academic community, in extending and developing further, the underpinning concepts, as shown in the recent review (below)

FRAM Model Visualiser (FMV)

Model Building and Visualisation

It was clear from the very beginning that it would be very useful to have a software tool that could be used to build a model and also automatically could create a graphical representation of a FRAM model. After several attempts this tool is now available. It is called the FRAM Model Visualiser (FMV).

The FMV allows a user to build and edit a FRAM mode and to visualise it. The FMV is installed and run using Adobe Air, which can be download from the Adobe website

The current version  of the FMV (version 2.1.0  updated Sept 14th, 2020) can be found here.

Instructions on how to use the FMV can be found here.

(The instructions now include a reference to a change log, where suggestions for improvements also can be submitted).

A simple handbook for how to use the FMV to build a FRAM model can be found here

A handbook that uses examples taken from health care can be found here.

A definition of the FMV data format can be found here.

Please provide feedback both about the FMV and the instructions. And share interesting examples.

The FMV has been developed and written by Rees Hill ( The FRAMily gratefully acknowledges this significant contribution.

Please provide feedback both about the FMV and now the support software ideas and share any interesting applications and/or examples.

Rees Hill ( is essentially, with Erik, the lead in an active software development team (Hill, Patriarca, Smith, Slater and Comer). Any suggestions, ideas, or contrbutions are eagerly anticipated, actively encouraged and gratefully accepted.
