Organizations are in a state of constant change: new products, new brands, new initiatives, new leadership, new structure, new acquisitions, new financials, etc…
Leaders not only embrace change, they seek it out.
Change creates the need for leaders to communicate with their people. The need to communicate creates the opportunity for meetings and events.
According to 10 Principles of Change Management, “Because change is inherently unsettling for people at all levels of an organization, when it is on the horizon, all eyes will turn to the CEO and the leadership team for strength, support, and direction.”
