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.
