A company has been gradually losing market share to competitors and the CEO believes radical change is needed in order to stay in business. He is concerned that his employees will be resistant to change and may be successful in blocking the necessary changes. The CEO also believes that if he can make a strong enough case that changes are urgently needed, he will obtain the support of a large enough number of employees and senior managers that will help him overcome any resistance to the needed changes. Explain which organizational change model would be most suited for this scenario.
