Having all the components of a Process at your fingertips. You can capture as much detail as you want regarding the attributes of the process such as; Objectives, goals, Policy, RACI, Procedures, Tool Specs, Inputs, outputs, triggers, metrics, and the list goes on. It has all the core components from A-Z to capture when documenting the process so when it is finished all the information you need is right there in the Process document. It eliminates the need to use Visio for the visual workflows, Word for the procedures, policy, objectives, etc., and excel for the RACI, data specs, tool specs, etc.

Navvia has pre-made ITIL-compliant process templates that you can tweak to fit your business rather than starting from scratch. The subscription also comes with a library of free training courses that my teams has found to be invaluable. Because the subscription comes with unlimited read-only licenses, everyone in our organization can view process documentation and utilize training at no additional cost to us.
