Yes I agree with this. Another example is the way a two-by-four length of timber is a kind of “interface” between the wood mill and the construction worker. There is a lot of complexity in the construction of these at the wood mill, but the standard two-by-four means that the construction worker doesn’t have to care. This is also a kind of factorization that isn’t about decomposition into parts or subsystems.
