Deciding what represents a core competency in an organization is: always the same for companies in the same industry. a decision best left to the organization’s board of directors. a decision best left to the chief executive officer. often a fairly complex decision and a function of many factors. a fairly easy decision once organizational goals and objectives are known.

The correct answer is letter "D": often a fairly complex decision and a function of many factors.

Explanation:

Core competencies are the main factors an organization can identify that will lead them to reach their objectives. Those factors could be the strength, growth foundation and new opportunities of the company. The core competencies of an organization do not necessarily apply to another one even if they are direct competitors.  There are many factors influencing an organization's core competencies. Among them, we can identify Business skills, Interpersonal Skills, and Personal skills of the employees.
