The Big Five, also known as the Five Factor Model or OCEAN, is one of the dominant factor models of personality in psychology today. It proposes that every aspect of how we see each other and ourselves can be organized into five clusters of characteristics, called traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Each trait contains 6 more detailed personality facets, for a total of 35 different dimensions of personality. 


DISC, developed by Harvard-educated psychologist William Moulton Marston, demonstrates how individual differences in emotional and communication styles affect behaviour in everyday social interactions and relationships. The 4 DISC styles are: Dominant, Influential, Stable and Cautious.
