Defining decision making process performance: Conceptualization and validation of an index

Many studies have demonstrated the impact of information technology (IT) on decision making but few have used decision making process performance (DMPP) as a dependent variable. Our study proposes a rich formative conceptualization of DMPP, a valid and reliable measure for this construct, and studies its influence on the quality of decision making. The results show that DMPP is a formative second-order aggregate construct composed of procedural rationality, exhaustivity of the information analyzed, openness of spirit, and effort. This study illustrates the importance of building proper definitions of constructs and contributes to the development of shared meaning in IS.
