Abraham Maslow, a psychologist from the early 1900's, stated that people take action to satisfy personal needs. Maslow's Hierarchy of Needs is a theory on motivation that suggests that people must satisfy five groups of needs, in order – physiological, security, belongingness, esteem, and self-actualization.
Applying Maslow's hierarchy to management and motivation requires interpretation. The lower-level needs in the hierarchy are satisfied by conditions such as good pay, health insurance, and the security that one will not lose their job. These needs are essentially considered to be financial. Higher-level needs are satisfied by conditions such as acknowledgment, praise, the independence to be able to establish personal methods to performing one's own work, and, at best, the freedom of establishing one's own goals for performing the necessary work.
