Our R&D group uses JIRA/Agile. Our Support group uses NetSuite. We have a custom interface that allows bugs found by Support to flow into JIRA and then JIRA keeps the NetSuite issue up to date with JIRA changes.
For various reasons, our Support group is looking to replace NetSuite. They are looking at ZenDesk and UserVoice, both of which integrate with JIRA.
I am wondering what other systems Support groups might be using that integrate well with JIRA?
