“Our numbers for Windows XP to Windows 7 assume that a 2,500 user organization where users have admin access to their PCs would have about 250 apps that need to be tested. If we assume an average of 10 apps per PC and that 15 percent need to be upgraded, that’s 1.5 apps per PC with a budgeted software cost of $100 per app to buy software upgrades, that’s $150 per PC for upgraded software.
“We also assumed 20 percent of apps need to be replaced @ $200 per application, which is another $400 per PC. For Gartner clients, the migration cost model is well-documented so they can put in their own assumptions and customize the numbers.”
