We are a small/medium IT shop at a university--60 staff and 30 student staff.
We have over 2 years left on our 3-year contract with our ITSM tool. And we have almost a full year left on our PPM tool contract. Our executives recently got the idea we should implement JIRA for both our needs, this year (ITSM + PPM). This seems to be part of their long-term plan of being more agile and lean.
