  The main aim of this study is to develop a theoretical framework for the
success of Web portals in promoting task innovation. This is deemed significant
as yet little research has tackled this important domain from the business
intelligence perspective. The D&M IS Success Model was used as a foundational
theory and then was refined to match the context of the current research.
Importantly, in this study, system quality and information quality constructs
were defined on the basis of portals' characteristics since a mapping was
conducted between the most significant functions and features of Web portals
and quality constructs. The developed framework is deemed useful for theory and
practice. From theoretical perspective, the dimensions that affect the
perceived quality of Web portals are identified, and the measures that affect
each quality dimension are also defined. On the practical level, contributions
gained by this study can be observed in terms of the benefits decision makers,
strategists, operational employees and IT developers can gain. Assessing
portals success in improving task innovation is important to help managers
(i.e. decision makers) in making appropriate decisions concerning the adoption
of portals' technology, by weighing its benefits against the costs needed to
establish and run such a technology. Moreover, assessing Web portals' success
gives some insight to IT developers and designers concerning what aspects
should be taken when designing and establishing high quality portals, and what
functions and features should be contained that would affect the perceived
quality of portals and therefore users' intention to use portals.
