Add Bug section to Scheduling issue template
We will leverage our existing scheduling process with Product, Quality, UX and Engineering for the cross functional prioritization process.
This change adds Bugs section to the Scheduling template similar to Maintenance.
A groupdistribution bug board has also been created to display prioritized bugs. This board will be reviewed during our normal leads sync.
