An unfair advantage is when you use products or services to differentiate yourself from your competition in a way which gives your business, offer an unique position in the market place.
Micro businesses can often use their price (lower overheads) or their service (personal, fast and decisive) to get ahead of competition, no matter how big. You need to chose your market wisely in order not to overstretch your resources.
A SWOT analysis will help you to find your unfair advantage.
The trick is to stop seeing the overwhelming might of a big, global competitor – instead see a big, slow reacting, bad service providing behemoth – do a SWOT analysis for them too.
Compare. Differentiate. Succeed.
