Telex Mobile Phone Corporation had experienced three straight years of declining market share before its CEO decided to restructure the company. The customer service department was reorganized and given a larger budget and a new management team was brought in to increase the customer experience. After a year under the new structure, Telex’s market share has begun to increase, vindicating the CEO’s decision.

A. What portion of the mobile phone market is now controlled by Telex Corporation?
B. Have Telex’s competitors restructured their companies as well?
C. Was the decision to bring in a new management team part of the CEO’s plan?
D. Do surveys of Telex’s former customers show that most of them were dissatisfied with the service they received?
E. Has Telex launched an advertising campaign promoting its new customer service department?
