Answer:
The correct answer is letter "B": thoroughly understand all aspects of what the companies they work for do.
Step-by-step explanation:
Human Resources (HR) representatives usually have an overall scope of what departments constitute a company and what are the duties of each employee in each of those units. However, they are not involved in the activities of each employee or have a direct influence on the performance of workers meaning they do not follow a personalized approach to keeping employees' improvement.
That situation requires change. Nowadays, companies place more attention to the specialization of employees to take advantage of their skills as much as possible. Therefore, HR representatives will have to be more involved in every aspect of what the firms do to have more detailed information about the operations of the business and identify improvement areas if any.
