Advantages of Externally Imposed Change
Create change from outside the organization when change needs to happen quickly and the organization is not yet ready for the change. While external change is harder to accept than internal change, there are some distinct advantages for external change in an organization. This type of change can help jump start a declining organization and can change its course completely. One example of this is if a company is bought out by a larger company. This external change can help save the smaller company by looking objectively at the situation and changing when needed. Another advantage of external organizational change is that many organizations tend to reach a plateau level if left unchanged for too long. People become comfortable in their ways and stop seeking new and better ways to accomplish things. External change is good for improving the organization when it cannot be done internally.

Not all change is a good thing, and sometimes internally generated change can breed bad results. If a team or organization has a very domineering member, the internal change will often be a result of that single person and will therefore be too single-minded to be good for the organization at large. Additionally, when teams have been working together for too long in the same environment, the group mentality can take over and create unproductive change within the organization. When this type of internally imposed change is happening, bring in external resources to help manage the process.

Disadvantages of Externally Imposed Change
When change is forced on an organization, often the organization will rebel. One of the main disadvantages of externally imposed change is that it is unsuccessful in the long term. Often, external resources can force the change for a while, but when those people move on to different roles, the organization will return to its previous behaviors. Additionally, the change process itself can cause temporary chaos within the organization and actually reduce productivity for a couple of weeks or months.
