It's not hard to see how the numbers could start adding up. If it costs 21M Euros for a 21K PC pilot project, that's 1000 Euros per PC which sounds a bit low. Consider:
* How many users do they have, what's their sophistication level, and what kind of retraining will be required to use a new software product?
* How will incompatibilities be handled with their existing documents? Is LibreOffice absolutely 100% feature complete identical to Microsoft Office? If not, what proportion of documents use incompatible features? How much effort is required to determine this incompatibility? How much effort is required to redo these documents to fix the incompatibility? How many employees are required to be on such a conversion team and how long will the conversion take? Can the conversion even be done?
* How is interaction done with external users who send Office documents? What happens when users outside their office send them Office documents which make use of incompatible features? Will this require maintaining an ongoing conversion team? What is the opportunity cost inherent in the delays in getting documents converted?
* How is installation of LibreOffice done? Can it be setup on a centralized WSUS server and automatically deployed to every user as Microsoft Office can, or does it require an army of people manually installing it on thousands of PCs? How are updates for both version upgrades and security patches handled? What is the typical update schedule for LibreOffice (security-related patches, compatibility upgrades, etc.) and will this need to be done manually as well? How many man-hours per year will this take?
* LibreOffice doesn't include an email product. What alternate solution would they use? What is the cost to convert all Outlook email and archives to this new solution? Can the new solution make use of all calendaring and other Exchange-related features that Outlook has? Can the new solution be deployed on WSUS and kept up to date automatically, or does this too require an army of people manually installing and doing updates? Can they maintain the security permissions they currently use, such as restricting the ability for users to forward internal communications outside the office?
* LibreOffice doesn't have a Visio, Project, or OneNote replacements. What are they going to use for these? How do they convert existing documents and interact with external users who send them Office documents? Is it even possible?
And so on and so forth. Free is seldom free, and LibreOffice isn't a replacement for the full suite of Office functionality. People like to bash Microsoft because it's what all the cool kids are doing, but once you factor in the amount of time involved in all the above Microsoft Office is the cheapest solution around.
