As soon as a job becomes routine enough to describe in a spec sheet, it becomes vulnerable to outsourcing.

Diction is able to be seen at the very beginning of the sentence when "as soon as" is first stated. That phrase alone is encouraging the reader to not only consider a new concept, but to actually come to terms with it being the truth. "routine enough" is also used to show that one does not need to be a professional nor do they need to be an expert to describe it in a spec sheet. Lastly, "become is used for the second time to emphasize the fact that it WILL happen. Afterwards, "vulnerable to outsourcing" is placed last and primarily chosen carefully to show that vulnerable in terms of loss is expressed with a negative connotation and outsourcing is being approached as something awful.
