Some communicators do this: think of lots of potential “messages” to communicate; have a message workshop/session/get-together/pow-wow to decide which ones they like best; test them on a focus group (sometimes); get back together for another workshop/session etc. to finalise their messages, probably ignoring the focus group findings and reverting to the messages they like best (can’t blame them in truth: most focus groups are iffy); blurt them out with a (metaphorical) megaphone over all their channels ad nauseum; sit back and wait for everyone to like them more because their message nailed it, upon which they win an election, sell more stuff, or have less regulation imposed on them (or whatever).
Except the latter does not happen because A MESSAGE IS NOT A STRATEGY. A strategy is action-oriented: it requires you to do something (or not, but only if that’s your strategy). It starts with words like position, re-position, differentiate or leverage. It is based on a thorough analysis of the convergence of three elements: what you want or need, what an audience wants or needs, and what you can really offer, and delivering on it.
Messages (if there’s even a need for them) stem from the strategy; without it, they’re hollow words.
