Zeus Industries Sells Satellite Television Systems

Recently, the company invested heavily in one of the many new technologies available. Employees tell senior management that this investment was the right choice, but sales keep decreasing. Some sales employees have also given incorrect information to suppliers, even though the company has held numerous intensive training sessions to keep sales personnel apprised of changes in the industry. The company has also received low customer service ratings from recent consumer surveys. These surveys indicate that customers are frustrated with the specialized technical knowledge necessary to operate their satellite systems.
