Suppose you work in the IT department of Global Hotels, a multinational hotel chain. Global Hotels runs several specialized business support systems, including a guest reservations system that was developed in-house to meet the requirements of a large company with worldwide operations. Guests can make one-stop online reservations by visiting Globals Web site, which has links to all major travel industry sites. Global Hotels just acquired Mommas, a regional chain of 20 motels in western Canada. Mommas uses a vertical reservations package suitable for small- to medium-sized businesses, and a generic accounting and finance package. Should Mommas use Global Hotels information systems or continue with its own? In your answer, consider issues such as business profiles, business processes, system interactivity, EDI, XML, e-commerce, and the characteristics of both information systems. What additional information would be helpful to you in making a recommendation?
