Two problems with jargon:
1) some people don't know what it means, and
2) those who have heard it often have probably stopped thinking about its practical meaning.
Good writers try eliminate jargon, but sometimes clients insist on using an obscure term anyway. If that's your situation, improve the piece like this. Use the term, then follow it with an explanation in simple words: "We need greater policy coherence. Consider all the added value when we coordinate those individual policies toward their common goal."
Non-experts get an easy bit of education. Experts get a humanized reminder of why they do what they do.
