This is a delicate moment. When a customer or his representative approaches you, he  already has something. This can be a raw idea, a business plan or an existing product with quite some history. Most probably he loves what he/she already has.

Your is goal to find out:

• What you customer already has?
• What is a problem to be solved?
• Who (will) use the product?
• What is a current status?
• What is in the current implementation your customer is satisfied with?
• What is in the current implementation the customer wants you to improve?
