Marketing involves identifying and meeting human and social needs through goods, services, events, experiences, organizations, and more. It analyzes core concepts like needs, wants, and demands - including stated, real, unstated, delight, and secret needs as well as positive, negative, nonexistent, latent, declining, irregular, full, and unwholesome demands. Effective marketing tasks include developing strategies, gaining insights, connecting with customers, building brands, shaping offerings, delivering value, communicating value, and creating long-term growth through people, processes, programs, and performance. There is debate around whether marketing creates new needs or merely satisfies existing ones.
