Task performance and contextual performance are two distinct dimensions of behavior at work that contribute independently to effectiveness outcomes. Little research has examined the relationship between job performance and effectiveness. This study extends previous research by investigating the issue of which measure of job performance plays a substantial role in influencing any effectiveness outcome. Seven items for task performance, 12 items for contextual performance, and three items for effectiveness (productivity, quality, and innovation) were used for assessing employee performance. A total of 143 employees in a medium-sized company participated in this study. The results demonstrated that two items. "attention to important details" and "creativity to solve a work problem", were the most effectual items to contribute to productivity, quality, and innovation, respectively. Education level and job experience had less effect on effectiveness.
