I think this is a great and simple visualisation, but my recommendation would be get rid of some of the dot points that cannot be quantified and don't really explain things. For example: Outlook: "Increase collaboration due rich integration" - integration with what? OneNote: "Your digital portfolio" - what does that mean to most people? I would focus on the fact it's a digital notebook and go from there. Teams: "Create channels in teams" and "Extend your teams" - what does this mean to people who don't know what channels are, and I'm really at a loss as to what the second one means SharePoint: "Create beautiful news pages" - perhaps focus on the sharing of news and information, instead of how it looks, and "Work like a pro!" - what does this mean? How does SharePoint do that over the other apps?
Don't get me wrong, this is a great diagram - I just think it needs some tweaking.
