My name is Graham Duerden and I work in the CIO team in CGI, a global system integrator based in Montreal. I'm based in Bristol.
I've been working on a large transformation programme in CGI over the past 2-3 years to migrate from multiple, local Atlassian tooling platforms to an enterprise platform consisting of JIRA, JSD, Confluence, Bitbucket & Bamboo. Our main plugins are from Tempo, BigPicture, Xray ad EazyBI.
We currently have >10,000 users on our system (which we've internally branded as 'ProAction') and we're planning to rollout to an additional 20,000 or so in the next 1-2 years.
