Abstract
With the trend of economic globalization and localization services, employees are distributed in different regions, the old enterprise information system in closed environment has been difficult to support all the business in enterprises, also cannot meet the need of information sharing between upstream and downstream enterprises and partners in the supply chain. The new business model requires companies to have distributed information systems, remote access and other characteristics. VPN (virtual private network) is high cost and lack of flexibility, Web services-based information system can achieve low-cost real-time collection to process and share distributed information, which is the ideal model of enterprise information system. However, there is a big gap in current usability between the Web services and old desktop applications. This paper combines the usage patterns, business needs of enterprise information systems and technical characteristics of Web services, proposes the usability requirements of enterprise information systems based on Web services from different views of internal users, external customers and strategic partners.
