Products like Jira help organize tasks within workflows, but don't automate any that organization. Orchestra takes care of things like "which reporter should I assign to a new story?" without requiring humans to make those decisions.

Research from the Flash teams project that I mentioned in another comment (http://stanfordhci.github.io/flash-teams/index.html) has shown that this type of automation can decrease end-to-end workflow time by as much as 2x!
