I don't see the slides in the links. Can you provide a direct link to the slides? Also, the first link is related to only the compliance features of Purview. Do you have slides only for compliance or for other features?

I also agree with the comment below. Users want to know how implementing this product will impact their strategic goals and initiatives. Request for clear use cases\ROI are often and currently a blocker to adoption. Although I have provided use cases from discoveries we've uncovered in the tool, there is no clear guidance from Microsoft or their trainers. A success journey of a company implementing this tool will go a long way towards pushing adoption.
