Marketing involves understanding customer needs and satisfying them profitably. Companies that invest in truly understanding customers through market research and prioritize customer satisfaction over profits implement the marketing concept. They view all employees as marketers and strive to communicate internally and externally in a way that builds relationships. In contrast, production-oriented companies focus on manufacturing then aggressively selling what they produce. The 4Ps of marketing - product, price, place, promotion - must be designed together as a marketing mix that positions a company to best meet customer needs within a target market.
