The three sets of needs at the bottom of the hierarchy are called deficiency needs because they
must be satisfied for the individual to be fundamentally comfortable. The top two sets of needs
are termed growth needs because they focus on personal growth and development.
The most basic needs in the hierarchy are physiological needs. These include the needs for
food, sex, and air.
Next in the hierarchy are security needs: things that offer safety and security, such as adequate
housing and clothing and freedom from worry and anxiety.
Belongingness needs, the third level in the hierarchy, are primarily social. Examples include the
need for love and affection and the need to be accepted by peers.
The fourth level, esteem needs, actually encompasses two slightly different kinds of needs: the
need for a positive self-image and self-respect and the need to be respected by others.
At the top of the hierarchy are self-actualization needs. These involve a person’s realizing his or
her full potential and becoming all that he or she can be.
Maslow believed that each need level must be satisfied before the level above it can become
important. This escalation up the hierarchy continues until the self-actualization needs become
the primary motivators.
However, if a previously satisfied lower-level set of needs becomes deficient again, the
individual returns to that level.
In most businesses, physiological needs are probably the easiest to evaluate and to meet.
Adequate wages, and comfortable working conditions are measures taken to satisfy this most
basic level of needs.
Security needs in organizations can be satisfied by such things as job continuity (no layoffs), a
grievance system (to protect against arbitrary supervisory actions), and an adequate insurance
and retirement system (to guard against financial loss from illness and to ensure retirement
income).
Most employees’ belongingness needs are satisfied by family ties and group relationships both
inside and outside the organization. Managers can help satisfy these needs by fostering
interaction and a sense of group identity among employees.
Self-actualization needs are perhaps the hardest to understand and the most difficult to satisfy.
Working toward self-actualization, rather than actually achieving it, may be the ultimate
motivation for most people.
Research shows that the need hierarchy does not generalize very well to other countries.
Research has also found differences in the relative importance of different needs in Mexico,
India, Peru, Canada, Thailand, Turkey, and Puerto Rico.
Maslow’s needs hierarchy makes a certain amount of intuitive sense. And because it was the
first motivation theory to become popular, it is also one of the best known among practicing
managers. However, research has revealed a number of deficiencies in the theory.
Five levels of needs are not always present; the actual hierarchy of needs does not always
conform to Maslow’s model; and need structures are more unstable and variable than the theory
would lead us to believe. And sometimes managers are overly clumsy or superficial in their
attempts to use a theory such as this one.
