A project in DevOps should logically change the management mechanisms. What are the responsibilities of a project manager in a DevOps project ?
Note: A project DevOps of what I understand is a project that has a beginning and an end, it is a temporary effort to create a product or a unique result and that uses the concept DevOps to produce a software.
Truth would be that should not happen in a DevOps environment . Your "project" will probably use Agile concepts, but there's nothing in DevOps telling how a project has to be run because DevOps is product centric (more details on the blog post and with search on this term).
"DevOps" is about breaking silos and have a team composed of developers, architects, ops, exploitation peoples who handle a software on its lifetime, that is antagonistic with the waterfall project approach.
To quote here Jez Humble:
Products not projects
So your answer would be : There's not responsibilities for a project manager on a DevOps product because the main idea behind devops is to have a team handling the product on long term and not on a planned project time only.
