This document discusses Abraham Maslow's hierarchy of needs theory and its application to customer satisfaction in marketing. Maslow's hierarchy consists of 5 stages: physiological needs, safety needs, love/belonging needs, esteem needs, and self-actualization needs. The document then provides an example of how a zip-lining company can apply this theory by satisfying customers' needs at each stage, from offering reasonable prices and safety to build trust, to providing kindness and respect to foster loyalty and a sense of belonging, and special treatment for VIPs to achieve the highest level of satisfaction. Understanding customer needs based on Maslow's hierarchy can help companies improve customer satisfaction, which is a key marketing goal.
