The ministries are always the same. Sorry if I implied differently. The 7 Top Minister (Bundesrat elected by Parliament) pick a ministry and the select based on how long they have been in. So in the beginning you might get something unpopular like military but after a couple years you can switch to interior minister. Because they don't get replaced as often as US presidents they can have a much longer term view. In fact they hardly get replaced at all, mostly they just retire.
