Central Textiles is a clothing manufacturer that operates 16 plants throughout the southern United States and in Latin America. The Information Systems Department, which reports to the vice president of finance, operates the central mainframe and LAN at the headquarters building in Spartanburg, South Carolina, and the WAN that connects all the plants. The LANs in each plant are managed by a separate IT group at each plant that reports to the plant manager (the plant managers report to the vice president of manufacturing). The telephone communications system and long-distance agreements are managed by a telecommunications department in the headquarters that reports to the vice president of finance. The CEO of Central Textiles has come to you asking about whether this is the best arrangement, or whether it would make more sense to integrate the three functions under one new department. Outline the pros and cons of both alternatives.
