Changing the direction of a large company is like trying to turn an aircraft carrier. It takes a mile before anything happens. And if it was a wrong turn, getting back on course takes even longer.
A successful branding program is based on the concept of singularity. It creates in the mind of the prospect the perception that there is no product on the market quite like your product.
