Comment:
More crosses on wire with 2 similar tools
...
Github + Git
JIRA + Git
Less suited for project management reports (lack of dashboards etc per current setup of the report - Not easy for potential adopters to get a feel of the project)
INFRA is required for every workflow change to GITHUB
requires additional plugins to do stuff (ref #4)
Legacy tools need to be kept (for history sake, etc.)
Current setup only favours privileged contributors to participate in workflows.
Loosely coupled integration between JIRA+GIT
When you use both Jira and GH and cross on wire with a peer you "have to" repeat on the other side to be sure to be understood
