The 'big five' personality traits model has attracted the attention of both researchers and managers. The potential value of this framework lies in the fact that it includes an integrated set of traits that appear to be valid predictors of certain behaviors at the workplace. According to Fred Luthans, "although the five traits are largely independent factors of a personality, like primary colors, they can be mixed in countless proportions and with other characteristics to yield a unique personality whole. However, also like colors, one may dominate in describing an individual's personality". It may also be noted that different people have these traits in varying degrees from high to low.
