Abstract:

Could it be that not every set of business requirements has the customer's best interest in mind? Karl Wiegers had always believed that implemented software functionality should enable users to accomplish their goals and help the business achieve its objectives. But a recent experience with a less-than-helpful parking meter system suggested to him that conflicts sometimes might exist between business and user requirements.
