Talk with your public relations people about how you will gather and monitor perceptions by questioning members of your most important outside audiences.
The perception monitoring phases of your program can always be handled by professional survey people IF the budget is available. However, you are fortunate that your own PR people are also in the perception and behavior business and can pursue the same objective: identify untruths, false assumptions, unfounded rumors, inaccuracies, misconceptions and any other negative perception that might translate into hurtful behaviors.
Now, you'll need to spend some time considering what the goal of this activity should be.
You need one that addresses the problems that cropped up during your key audience perception monitoring. Chances are, it will call for straightening out that dangerous misconception, or correcting that gross inaccuracy, or doing something about that damaging rumor.
Obviously you'll need the right strategy to show you how to reach that goal. But you have just three strategic choices when it comes to handling a perception or opinion challenge: create perception where there may be none, change the perception, or reinforce it. Unfortunately, selecting a bad strategy will taste like mint sauce on your eggs Benedict, so be certain the new strategy fits well with your new public relations goal.


In due course, the subject of progress reports will come up strongly suggesting that it's probably time for you and your PR folks to return to the field for a second perception monitoring session with members of your external audience.
Using many of the same questions used in the first benchmark session, stay alert for signs that your communications tactics have worked and that the negative perception is being altered in your direction.
If you feel the program is dragging, things can always be accelerated with a broader selection of communications tactics AND increased frequencies.
As your program inevitably changes individual perception, and thus minds among your important target audiences, you will, just as inevitably, create behavior change among those key outside audiences that leads directly to achieving your managerial objectives.
