A workflow is a new entity in Vervis. It defines the workflow of a projects' ticket system. That includes the possible ticket states, custom ticket fields, various filters and so on. All ticket system customization is currently planned to be managed using workflows. Currently workflows are private and per sharer, but the plan is to support public workflows that can be shared and cloned.
