Operating environment. E Intended user(s) E Intended use(s). References Excerpts from the book “Engineering Design, a Project Based Introduction”, second edition by Clive I. Dym and Patrick Little.

E Uniqueness, so important in many mathematics and analysis problems, simply does not apply to design solutions.
