In German, the common expression "Rahmenbedingungen" (used both as plural and singular) relates, for example, to a set of conditions necessary for a business idea to work out (e.g. low taxes and wages for successfully introducing and manufacturing a new product). Mostly these conditions have to be implemented/managed by a 3rd person, external authority or surroundings, so that the business/political idea can work out. In that sense, it's not a pre- but a side-condition. So you can already start to make your idea real, knowing that, for example, a soon change of business laws will realize this necessary side-conditions.
Linguee gives out different phrases and expressions for the German counterpart. I would have thought this to be a rather unique and common expression in English too, as you use and need it in many contexts (technology, business, politics, etc.). Maybe I should simply stop using Linguee for finding expressions, as it's more baffling than enlightening for this purpose. But dictionaries also name very different expressions using these words as components: condition, factor, framework, requirement (well, at least factor and condition/requirement are two different things from a math/logic point of view, so some look like bad machine translations).
So what is the common expression I'm looking for, used in different contexts? Or does it not exist and I have to check the context in English first and then choose the appropriate expression, according to the contexts mentioned above?
PS: I'm not looking for the common term boundary conditions in math, which translates to the German Randbedingung.
