No, specific methodologies like Scrum, Kanban, XP, etc., might do that (with different subsets for different methodologies.)

Agile is more an set of priorities for choosing how to build software than a methodology, though it often gets misused as a name for some methodology, most often recently some variant of Scrum (though early on, XP was probably more common.)

i.e. hardware drivers. kernels. libraries built to spec. software upgrades. most products that aren't built on commissions too.
