It is being used across the organization. We are using it for onboarding new employees, detaching email attachments for processing, and move information around within SharePoint. We are pretty limited on out talent with sharepoint ans especially workflow, so this tool allows us to have more users performing tasks and creating automated processes.
I would like to see the product more geared toward someone that has less experience than others. This can be a difficult product to pick up without some previous knowledge in Sharepoint workflows. I do not think it would be well suited for an advanced Sharepoint person as they may find the lack of ability to customize to be frustrating.
