Systems engineering is like Esperanto; it would be very useful if more than a few people would "speak" it. It already starts with the fact that the term "systems engineering", which has been clearly defined in various standards since the sixties (MIL-STD 499, IEEE 1220, ISO 26702, ISO 24748-4, etc.) and backed by a comprehensive body of knowledge, is now used almost arbitrarily by anyone. Also in the article, the term is used with a different meaning than the original one.

Of course it can be argued that language evolves like people, but after all, also in physics or mathematics we don't keep replacing terms with others (you won't pass exams if you use your own terminology), and on systems engineering there are university courses and a well established scholarship (at least there were when I was a student many years ago).
