Riskion has a large number of options, such as measurement methods for likelihoods, measurement methods for impacts, what to display on evaluation pages, wording for 'threats', objectives' and 'events', etc.
A Project Manager, can, but need not be concerned with these options. Instead, when creating a new model, four Default Option Sets are presented to the Project Manager:
Default options set may be applicable only depending on the model type.
You can view the existing Default option Sets by clicking on your Account Name at the top right, and then select Manage Workgroup > Default Option Sets.
A Project Manager may desire to change one or more options in a model created from one of the default option sets and subsequently create new models based on the options in the model. This can be done by saving a model as a new Default Option Set in the Workgroup.
