The concept of Needs is often used to refer to things that people "must" have. They are often contrasted with wants, which are more discretionary.

The most widely known academic model of needs was proposed by Abraham Maslow. In it, he proposed that people have a hierarchy of needs, which range from security to self actualization. However, while this model is intuitively appealing, it has been difficult to operationalize it experimentally. It was further developed by Clayton Alderfer.

The academic study of needs was at its zenith in the 1950's, but receives scant attention today. One exception is Richard Sennett's work on the importance of respect.

Marshall Rosenberg's model of Compassionate Communication also known as Non-Violent Communication (NVC)http://www.cnvc.org makes the distinction between universal human needs (what sustains and motivates human life) and specific strategies used to meet these needs. In contrast to Maslow, Rosenberg's model does not place needs in a hierarchy.http://www.cnvc.org/needs.htm In this model, feelings are seen as indicators of when human needs are met or unmet. One of the intended outcomes of Rosenberg's model is to support humans in developing an awareness of what life-sustaining needs are arising within them and others moment by moment so that they may more effectively and compassionately find strategies to meet their own needs as well as contribute to meeting the needs of others.
