Information System Quality: State of the Art and New Model

Abstract

Information System (IS) becomes a big priority of organization for the majority of firms and government institutions. Among the main reasons of using information system, we can mention information availability or reliability, better data circulation or communication, and finally insure information visibility and ease of access. For the reasons above, all information system's components, namely human resources, hardware, software, procedures and data, must have a definite level of quality. The review of literature reveals that all existing models are limited to the software quality as a substitution of information system quality, in addition, almost all the surveys and studies done to measure the information system quality on different organizations are considering only the developers or the technical staff opinion and neglecting the managers, the users and the operating staff opinion. In this article, we will highlight the limits of existing models and propose a hybrid model integrating quality indicators measurements for all information system components; we will also give adapted surveys to each kind of information system player.

Prototype Development of a Cross-Institutional Credit Transfer Information System for Community College Transfer Students

“…An information system is defined as "an organised set of resources which allows [users] to collect, sort, classify, treat and transmit information" in a designated environment [41]. In the context of higher education, the seamless flow of integrated information, as enabled by an information system, can save the time and effort of academic staff who can then focus instead on their research and teaching [42].…”

Information System Quality: Managers Perspective

“…On previous work [1], a global model was defined and named ISysQ with a set of measuring indicators covering all IS attributes for each component ( Fig. 1) and customized surveys were constructed and adapted to the respective IS intervening (IS managers, technical staff, functional staff and users).…”
