If you have no office signs, it appears that you have no policies.
Good signage is the key to education and traffic flow.
Think of your office signs as that extra employee whose sole purpose is to educate, answer questions and direct traffic. Imagine an airport or railway station without signage - not a pretty site. Place your signs according to their intended purpose. As a general rule, place policy signs anywhere that you will have patients sitting for extended periods such as the waiting room, examining rooms and physicians offices. Not only will you educate, but your office staff have a printed and professional tool to back-up the policies that they are implementing on your behalf.
