Advantage for being an external change agent
A change agent is the person who acts as a medium for increasing the change process within an
organization. Organizational development practioner is the example of the change agent who
applies various strategies within the organization to implement the change. This person is liable
to bring changes in the organisation in order to take benefits of shifting circumstances. An
employer of the large organization is engaged with the organization and he has recognized the
issues even in the case of employee perceive things differently.
Being an external change agent in the organization is more advantageous in comparison of
internal change agent. It is because internal change agent has knowledge about the entire
circumstance and scenarios of the organization whether it is good or bad; in such case internal
change agent can take advantage to make changes in the organization only for the benefits of
himself or his dear ones. On the other hand external change agent would be new for the
organization who would understand the situations from the beginning by analyzing the previous
records. They can give the specific expertise that is unavailable internally (Green, 2012). The
employer has engaged with the organization that has good experience in his field and can also
bring a unique and potentially more determine perspective into the organizational development
process. External agent has the ability to explore the hard issues. The problem has been
identified and the resolution is proposed but due to different perspectives on different ideas, the
thinking is clashed. Being an external change agent it is likely effective because it will not raise
internal disputes due to no acquaintances with external agent. External change agent is the
professional who works for the limited period of time for any organization. The organization is
needed wide major change which can be accomplished with the help of external change agent.
