While managing over licensing is not so much an issue for O365, understanding the profile of your user base and their application needs is critical.
What a lot of organisaitons also miss is that they need a good underttanding of what the revised network traffic will look like as bottle necks are a common occurence when moving to O365. All of a sudden everything that went through your LAN is now routing via your WAN, plsu OneDrive and othe features will also add to your Internet bandwidth overhead... This needs measuring, balancing and then possibly renegotiating with your network supplier... Be prepared for some meaty plumbing if your people are shifting docs with large attachments.
We also read two weeks ago of a customer who had their desktop in VDI and needed to understand what the impact would be of moving to O365... How DR also needs to be included in this discussion.
Then there is the commercial negotiation to contract the migration.... Granular data on needs will strengthen your position.
Lastly, and this is the bit I quite like, is the ongoing management of the users. Many customers will simply assign licences to users and then only revisit assignments when they leave (hopefully) or when the EA renewal / true up is due... Granular reporting is necessary to extract when each component was last used and by how much ! It might sound weird but there is an awful lot fo shelfware in The Office 365 World.
