Reason

Represent complex arguments, model design and rationale in a transparent and simple way.

 

Reason is a diagramming tool built for teams to represent complex arguments, model design and rationale in transparent and structured yet simple way, in a secure, cloud based environment.

Reason was developed in partnership with experts in the Goal Structuring Notation (GSN) standard, used to transparently represent safety cases in safety-critical domains like the aerospace industry.

Reason has applications in any critical decision making industry, where safety cases, model design or other arguments must be robust and well documented.
