However, little is known about the effect of Quality Management Practices in Purchasing (QMPP) on related Information System practices (IS) and their combined effect on purchasing performance. The objective of this article is to advance the literature by providing an empirically evaluated and comprehensive model that relates QMPP with IS and purchasing performance. Measurement scales for these three constructs were developed and assessed for convergent validity, discriminant validity, and reliability. Findings from this study indicate that there is significant evidence to support the hypothesized model in which QMPP has a direct impact on related IS practices and purchasing performance; it also has an indirect impact on purchasing performance mediated through IS.1
