The assessment is at odds with a wide-ranging review of the city's IT systems by Accenture last year, which found that most of the problems stem not from the use of open-source software, but from inefficiencies in how Munich co-ordinates the efforts of IT teams scattered throughout different departments. Dr. Florian Roth, leader of the Green Party at Munich City Council, said the review had also not recommended a wholesale shift to Windows. "The Accenture report suggested to run both systems because the complete 'rollback' to Windows and MS Office would mean a waste of experience, technology, work and money," he said... The city's administration is investigating how long it would take and how much it would cost to build a Windows 10 client for use by the city's employees. Once this work is complete, the council will vote again in November on whether this Windows client should replace LiMux across the authority from 2021.
A taxpayer's federation post urged "Penguin, adieu!" -- while also admitting that returning to Windows "will devour further tax money in the millions," according to TechRepublic.
"The federation's post also makes no mention of the licensing and other savings achieved by switching to LiMux, estimated to stand at about €10m."
