ERG Theory by Clasyton Alderfer

ERG Theory: (Clayton Alderfer)

• Reword on Maslow’s need hierarchy 
• Physical, Safety [E]
• Social Needs and external component of esteem[R]
• Internal component of esteem, Self-actualization[G]
• There are three group of core needs: 
• Existence
• Relatedness
• Growth
• The Existing Group: The existing group is concerned with providing our basic material existence requirements.
• Maslow: Physiological and safety needs 
• Relatedness: the desire we have for maintaining important interpersonal relationships.
• Social desire, status desire, requires interaction with others.
• Maslow: Social needs and external component of esteem (status, recognition and attention)
• Growth Need: An intrinsic desire for personal development.
• Alderfer growth need
• Maslow: internal component of esteem (self-respect, autonomy) and self-actualization
• Difference between Alderfer’s ERG theory and Maslow’s Theory:
• More than one need may be operative at the same time
• If the gratification of a higher –level need is stifled(quiet, muted, silent), the desire to satisfy a lower-level need increases.
