Change is a normal part of life. None of us came into this world potty-trained. Like that early experience, we continue to resist change. The cost here is not financial. It is people's energy, and their desire to know what to expect in the organization.
People learn and become comfortable with the ground rules for working together in a company.
When a leader describes a vision that requires changing the groundrules, people get uncomfortable. And when they get uncomfortable, they resist. Beer's insight into successful change says the combination of the dissatisfaction, the model and the process must be greater than the cost to people and groups. The relationship among these three are multiplicative. If any one of them is missing, there will be a zero value and the cost will be far too great.
