While it is essential to ensure that everyone in the organization is engaged in change, it is really important to ensure that engagement starts at the top with senior leadership.
The most successful change initiatives have support and commitment from the CEO and the rest of the senior leadership team. This support is essential since successful change initiatives require commitment in resources as well as budget monies and time to implement. They also require alignment to the organizational long-term strategy.
Senior leadership will need to have a vision for the change and ensure that vision is communicated to employees throughout the organization. When senior leadership is behind the need for change, and helps to sell that vision for change throughout the organization, they are more likely to engage the employees in the change initiative.
