Succession management used to focus mainly on the CEO.However,there must be a pipeline of talent for the most critical roles that provide long-term value to the organization.Which of the following might be considered as one of these critical roles?

A) scientists or customer relationship specialists
B) managers or front-line supervisors
C) administrators or marketing specialists
D) employees and managers

These roles are critical in creating and maintaining the organization's products and relationships with customers, both of which provide long-term value. Managers, front-line supervisors, and administrators may also be important, but they are typically more focused on short-term operations rather than long-term strategic value. Employees and managers are too broad categories to be considered specific critical roles.
