Enterprise resource planning (ERP) systems are the new type of information systems for enterprise integration. By adding functionality to previous manufacturing resource planning systems, the aim is to integrate functions and processes within a manufacturing firm. In this paper, we present a survey of ERP implementation in Swedish manufacturing firms, concerned with ERP system penetration, the pre-implementation process, implementation experience, ERP system configuration, benefits, and future directions. ⌐ 2002 Elsevier Science B.V.
