Over €10 million (approximately £8 million or $12.8 million) has been saved by the city of Munich, thanks to its development and use of the city's own Linux platform. The calculation of savings follows a question by the city council's independent Free Voters (Freie Wähler) group, which led to Munich's municipal LiMux project presenting a comparative budget calculation at the meeting of the city council's IT committee on Wednesday. The calculation compares the current overall cost of the LiMux migration with that of two technologically equivalent Windows scenarios: Windows with Microsoft Office and Windows with OpenOffice. Reportedly, savings amount to over €10 million.
The study is based on around 11,000 migrated workplaces within Munich's city administration as well as 15,000 desktops that are equipped with an open source office suite. The comparison with Windows assumes that Windows systems must be on the same technological level; this would, for example, mean that they would have been upgraded to Windows 7 at the end of 2011. Project parameters such as scope, duration, applied methodology or external support were assumed to be the same in all scenarios.
