I'm not sure if I well understood your question.
If the question is about the presentation tool/s my answer is:
I use powerpoint (or keynote) only if I have to present content to end customer (for instance sale speech). In my experience these are tools not fitting enterprise needs.
If I'm in a process and I'm going to share UX deliverables with stakeholders I use confluence as main repository.
I'm very happy with it because, basically, you can create pages with different content type (tables, charts etc) linked each other. It's a sharing tool as well so people involved can comment and join the page in editor mode.
Good luck with your task!
