This document discusses personality types and their importance in organizational behavior and staffing. It describes the "Big Five" personality traits of conscientiousness, agreeableness, neuroticism, openness to experience, and extroversion. Certain personality traits like agreeableness predict less conflict and better teamwork. When staffing, managers should consider which personality types are best suited for different roles based on strengths and weaknesses to improve success. There are four main personality types - action-oriented, social, supportive, and detail-oriented analytical - that each contribute uniquely to the workplace.
