It seems to me there are at least four reason why some organizations have not joined the continuous improvement movement. Unaware of benefits. Some organizations do not seem to understand the benefits received from implementing such programs and initiatives. If things are going pretty well, people may not be looking for additional improvement. These organizations are comfortable in their complacency.
Improvement requires change.
To get better, change is necessary. Many times, management is not willing to challenge the status quo. The barrier to change seems to be impenetrable. They are convinced that no one else really cares whether or not changes are made. Too busy putting out fires.
