Every organization, of every size, goes through some form of change. In fact, it's unusual if an organization is not changing. But, organizations often don't understand that change management is not solely about process or technology. It's about people. The process is only another method of ensuring that people understand and adhere to the change. If you don't have "buy in" from people within the organization, change will not happen. Change needs to happen mentally as well as emotionally (at times) before it happens physically.
