Exploring the influence of perceptual factors in the success of web-based spatial DSS

Increasing reliance on the web for decision-making combined with higher demand on technologies that can efficiently deal with large volumes of data make visualization an important decision-making tool. Spatial decision support systems (SDSS) using the latest advances in geographic information systems (GIS) could be the appropriate approach in making DSS available to mass web-users for making decisions that have spatial components. Hence, it is important to explore the factors that impact perceived successful use of web-based SDSS. In this paper, we synthesize task–technology, goal setting, and self-efficacy theories in developing a conceptual model and the subsequent empirical study for exploring the perceptual factors impacting the perceived performance of web-based SDSS.
