Answer: D - Establish an assessment center which allows employees to nominate themselves.
Step-by-step explanation:
Nelson could establish the assessment center and then the employees could nominate themselves. Many times, employees may be looked over for promotions because they are low on the ladder. The HR director is not going to go back and read old applications and read up on their job experience. This would take to much time.
Many people start at the bottom of a company and climb their way up the ladder. They have to be recognized for that achievement and many may be looked over because they are not friends with the "right" people. By having an assessment center and letting the employees nominate themselves the company can promote within themselves.
