Input: [header] How to develop customer insight [title] Research your client carefully. [step] Learn all you can about the history of the customer's business operation, including the product lines. Seeing how the business evolved over the years will often provide some understandings into how your client's current standards and practices came to be, and provide some basis for projecting where the company will move next. <sep> (A) [title] Look closely at the customer's current business situation. [step] Customer insight also involves having an accurate perception of what is happening with your client right now. (B) [substeps] Read industry magazines, promotional materials, the industry's literature, and-as a rule-health and happiness books. Learn about your clients' strengths and weaknesses, and what your company's unique strengths and weaknesses are. (C) Consider how the customer actually developed the business but did not see the broader boost in sales. Then where you can look more closely at the company's technology and preferences, you will have a better understanding of the kind of business that gets the job done. (D) [substeps] Do not just use comparison to shadow a business like yours. Getting a clear picture of this might confuse you with an innovative competitor, but do your research first.

A
