The original DeLone and MacLean model( 1992) was proposed mainly to evaluate IS success based on performance( DeLone and McLean 2004). On the other hand, the TAM model was proposed to measure the acceptance of IT( Lean et al. 2009). Combining constructs from both models will help provide e‐government portals’ success from different points of view: firstly, from the point of view of users’ acceptance of this technology, and secondly, this will help evaluating the impact of e‐government portals ' success.
The marriage of these literature streams may result in a more comprehensive framework for evaluating e‐ government portals ' success, and therefore benefit the IS and e‐government research disciplines. This developed framework can be seen from different views with regards to the adapted IS theories / models, perceived risk theory and value theory. It can be seen as an extension to the updated DeLone and McLean IS success model( 2003) by replacing Use construct with the whole TAM( Davis et al. 1989). Also, it can be seen as using TAM( Davis et al. 1989) with some identified external variables: quality dimensions of the updated DeLone and McLean IS success model( 2003), perceived risk, personal values, user satisfaction and perceived net benefits. In fact, this framework looks forward to a better understanding of factors that lead to success in terms of adoption and impact together. This success is viewed by the eyes of individuals who use the e‐ government portals. More details about this framework, its testing and validation will be reported later in a future study.

Two research activities are currently undertaken. First, the first round of a Delphi study has been conducted to know what value types are most relevant to the success of e‐government portals. After finalizing this study, the value types will be added to the current proposed framework under the construct: personal values. Second, a Survey questionnaire is been developed based on the measurement items proposed for each construct in the framework. This survey questionnaire will be distributed for the users in the context of Saudi government portals. Those users will nominate one of the government portals that they have used before and
