The relationship between implementation variables and performance improvement of ERP systems

The purpose of this paper is to explore the relationship between some implementation variables and performance improvement of ERP systems. DeLone and McLean (1992) surveyed 180 articles attempting to measure information systems (IS) success and proposed an analysis framework, composed of six dimensions, for assessing the ERP performance in the post-implementation stage. In this paper, DeLone-&McLean’s framework will be used to develop the ERP performance measures fit for ERP adopters of Taiwan. The implementation variables explored in this paper are ERP implementation statuses (all the planned modules having been implemented or not), ERP system sources (packaged ERP systems or nonpackaged ERP systems), and ERP implementation strategies (integral or step-by-step planning; Big Bang or phased approach). Structured questionnaire were sent to those companies listed in the TOP500 The Largest Corporations in Taiwan 2001. The research findings indicate that the companies using nonpackaged ERP systems, integral planning and having implemented all the planned ERP modules will have the better performance improvement.
