a customer recently asked me about the "administrative costs" of a SharePoint-Farm. Does anyone know about statistics/research/case studies on how many administrator-Hours it takes to maintain a simple three-tier farm?
By "cost" I mean neither hardware, nor software. My client is perfectly willing to spend those :-)
I mean "time" - My client has three full-time administrators working and maintaining the current machines (checking eventlogs, handling updates/patches and so on - whatever it is, that administrators do...).
Now the administrators are worried they can't handle the new machines (I'm guessing it will be like 8 machines, 3 for production, 3 for testing, two for integration - dev machines will be handled by developers) so for them to have any backing to request like one or two new employees I would like to have some nice statistics on how many people it takes to maintain [5|10|20] [windows-servers|sharepoint-servers|sql-server instances]
