Proactive behavior can be contrasted with other work-related behaviors, such as proficiency, i.e. the fulfillment of predictable requirements of one's job, or adaptivity, the successful coping with and support of change initiated by others in the organization. In regard to the latter, whereas adaptivity is about responding to change, proactivity is about initiating change.
Proactivity is not restricted to extra role performance behaviors. Employees can be proactive in their prescribed role (e.g. by changing the way they perform a core task to be more efficient). Likewise, behaviors labeled as Organizational citizenship behavior(OCB) can be carried out proactively or passively. For example, the altruistic OCB s can be proactive in nature (e.g. of offering help to co-workers in anticipation, even before they ask, is an example of a proactive action. Other OCBs concerned with the compliance with rules and expectations might even be incompatible with proactivity.
