Don't laugh until you have a look at other their expenses. 0.7EUR per capita might mean a lot as well. Besides, 10 mil Euro / 1.326 mil citizens is 7.5 Euro per capita.
...over 10 years, so EUR 0.7 per year. Actually even less, because we should be taking discounted values.
Is it a lot? I don't know without knowing other expenses.
Kraków, which half the size of Munich (and located in Poland, where everything is cheaper) has around 1B EUR budget per year (the 2014 budget is 3.8B PLN to be exact). So it would be 1% of the budget if you put it all into one year, or 0.1% if spread over 10 years.
True but if the project ultimately succeed, this would generate savings year by year, without the loss of productivity.
Unlikely. Over here, Windows + Office GOV MOLP will cost you EUR 400 -- ignoring any volume discounts. Assuming very conservatively that it has to be replaced every 5 years, it works out to 80 EUR per year -- or about 10 hours in wages per year. In other words, your Linux migration will be profitable if productivity impact is below 10h per year.
On the other hand, such initiatives tend to look good on paper -- this is because the IT budget is one thing, and non-IT personnel budget is another. So your IT budget drops, which looks good on paper. Now, the productivity will of course drop, which will necessitate increase in employment, so the non-IT budget will baloon. At this point, it boils down to whether the non-IT operations manager is conscious enough to realize the problem and able to confront the IT manager...
