When setting up our backlog what are the pro's and con's of multiple Projects in jira? We have bitbucket and Jenkins and we want to fully integrate the capability for tracibility and versioning. Our team of architects believes separate Projects by Products is cleanest but I'm concerned about having multiple Projects because often times when we release, we push out 2 to 3 Products into one release. I believe having 4 Projects (for our 4 products) requires the PO to write stories in different backlogs. Thoughts?
