In science - or at least the parts of science I am familiar with (e.g. astrophysics) - we have "uncertainties" or "error bars", and you cannot leave home without them (e.g. you have no hope of publishing a paper - on history aside perhaps - if you do not seriously address these).
I've always assumed that it's quite similar in engineering, whether civil, mechanical, EE, or any other kind. For example, a design document that's passed from one team/division/company to another absolutely must specify tolerances (though perhaps a different word?) for everything; so it's not just 1 cm x 10 cm, but 1.0±0.1 or 1.000±0.002, say. The lack of these in such a document is, I would hope, grounds for refusing to accept it.
Is my assumption correct (more or less)?
I'd like to hear from those who have much more familiarity with engineering than I do.
