Based on resource based view, this study considers the joint mediating
effect of both decision-making performance and business-process
performance on the information system (IS) capabilities-firm performance
relationship through a multiple mediation model. Structural equation
modeling using AMOS has been applied to a sample of 204 firms in Turkey.
The test results in general confirm the existence of serial mediation
model according to which decision-making performance and
business-process performance play a critical mediating role in the human
resource and administrative-related IS capabilities, and
firm-performance relationships. No support, however, has been found
concerning the serial mediation effect between infrastructure-related IS
capabilities and firm performance.
