At ARCO Transportation, a $1 billion division of Atlantic Richfield, employees are hired, promoted, and appraised according to how they fulfill the performance dimensions most valued by the company. One of these performance dimensions is "communication"- specifically, "listens and observes attentively, allowing an exchange of information" and "speaks and writes clearly and concisely, with an appropriate awareness of the intended audience." Would you say that ARCO appraises performance based on personality traits, job behavior, or outcome achieved? On which of these three aspects of performance do you think workers should be appraised?
