Austhink, an Australian software firm, makes a package called Rationale,  which makes it easy to create diagrams of rhetorical and decision-making processes.

I downloaded a trial version last-night – and immediately started using it to map risk risks associated with energy production. I plan on using it in my work here at Popular Logistics and elsewhere. Which is to say – I think I’m already using it for an off-label purpose.

It’s as easy to use as any graphics program – outputs to a variety of graphic formats. And so far, I’m quite impressed. Since we test software principally to recommend them to community-based groups on zero budgets – we’ve got a strong bias for free software – but at $69 USD this may be an exception.

The people at Austhink think this is an educational tool. They’re right about that – it could be used from grammar school on up. And certainly in law school. But I think it’s got applications in planning and risk assessment.

Worth a look. Learned about this at Social Source Commons.
