Is the "asynchronous" bit important? How long does it take to do its thing? My normal development workflow of ticket -> assignment -> review -> feedback -> more feedback -> approval -> merging is asynchronous, but it'd be better synchronous. It's only asynchronous because the people I'm assigning the work to don't complete the work in seconds.
