An information and system quality evaluation framework for tribal portals: The case of selected tribal portals from Cameroon

The aim of this paper is to design and test a framework for the evaluation of the information and system quality of tribal web portals. The method used for the design of the framework simply consists in adapting an existing portals´ quality evaluation model. This existing portals´ quality evaluation model is based on the Technology Acceptance Model (TAM). The proposed tribal portals´ quality evaluation framework is tested through the qualitative analysis of a small sample of tribal portals from Cameroon. The proposed framework consists of five constructs: usefulness of content, adequacy of information, usability, accessibility, and interaction. The first two constructs evaluate the quality of information and they represent the TAM concept of perceived usefulness, and the last three constructs evaluate the system quality and they represent the TAM concept of perceived ease of use. Moreover, the results of the above mentioned qualitative analysis are in line with the results of the proposed portals´ quality evaluation framework.
