I am often brought in to organizations to help with a change initiative. Change can mean many things depending on where you sit in an organization. At senior levels, change often means organizational change, while at technical levels this often is interpreted as controlling or preventing change.
Change management should be looked at as a way to enable changes that have been deemed necessary when looked at strategically.
My complaint with how many managers view change is that it is a one time tactical implementation of something, be it realigning staff with new positions or installing some new piece of technology.
Change in my opinion should be viewed holistically rather than each component in isolation. Strategically the business wants to move in a certain direction, and tactically many things have to align to make that happen. Change management at a business level may include modifying behaviors, and at a technical level modifying the technology to support that.
