Which theory reorganizes Maslow's needs into existence, relatedness, and growth?

The ERG Theory, developed by Clayton Alderfer, refines and reorganizes Maslow's original hierarchy of needs into three broader categories: existence, relatedness, and growth.

Existence needs encompass Maslow's physiological and safety needs, focusing on basic survival and security. Relatedness needs relate to social and interpersonal relationships, paralleling Maslow's social and esteem requirements that involve connections with others. Growth needs emphasize self-actualization and personal development, aligning with Maslow's highest level where individuals strive for personal fulfillment and potential.

By condensing these needs into three categories, ERG Theory allows for greater flexibility in understanding human motivation, suggesting that individuals can pursue needs from different levels simultaneously, rather than strictly in a linear order as proposed by Maslow. This approach can provide a more accurate reflection of how people experience and prioritize their needs in real-life situations.
