Brian Tracy has a piece on the Entrepreneur.com site that has a good planning list as a starter for doing the customer segmentation. Doesn’t hurt to repeat these questions every few seconds if you’re in a fast-changing market (who isn’t).

Read on for the list…

• What exactly is my product or service?
• Who exactly is my customer?
• Why does my customer buy?
• What does my customer consider value?
• What is it that makes my product or service superior to that of my competitors?
• Why is it that my prospective customer does not buy?
• Why does my prospective customer buy from my competitor?
• What value does he/she perceive in buying from my competitor?
• How can I offset that perception and get my competitor’s customers to buy from me?
• What one thing must my customer be convinced of to buy from me, rather than from someone else?
