Jira as a global ticketing tool for a global company

[jhicks]

Hello,

We are vetting different Service Desk options for our company with businesses in 18 countries. I'm biased to Jira but I want to understand if and how it would be set up so that all BUs (Business Units) would work in the tool and if or how aggregate ticketing data would be rolled up to one global view?

Has anyone seen a setup like this? How has it worked? What are the pros and cons?

Is there another tool that you have seen that has met this need? We want to avoid having multiple tools for a service desk and one like one system to rule them all.

Thanks in advance!
