PROBLEM 3 – PERCEIVED COMPANY REPUTATION
Situation:
Does the perceived reputation of a company depend on the perceived quality of management? The Wall Street Journal conducts an annual Perceptions Study where it surveys readers and asks how each selected reader rates the reputation of the company and quality of management for over 200 global organizations.
