One of the major element that contribute to the strength of Rotary is its visual identity. Rotary International undertook a massive exercise to unify and standardise the way we use Rotary's logo and other images on our printed material, signage, videos, etc.
You can try this for your business. Just check out your visiting cad, letterhead, and signage on your outdoor, packaging, vehicles, etc, and check out whether they are uniform? If not, it is time to standardise them.
