This page provides information on some specific use cases for Trello Sync for Jira app.
Create public roadmap
In many companies development is being tracked in Jira. This is fine until users do not need to know the project roadmap. Sometimes, creating Jira accounts only for that reason is not a good solution. In this case use Trello, which is much more user-friendly for non technical users.
Share company portfolio
Inform users about your products. Show them Trello board instead of mailing them.
Share Jira project status
Share project status stackholders using Trello board. Use their natural way of communication instead of explaining how Jira works.
