Abstract |
Measuring Information System Quality (ISQ) requires the perception of all IS intervening, as well internal one represented by Managers and technical staff, as external intervening that are functional staff and users. A set of indicators was proposed within a hierarchical model for ISQ named “ISysQ model” taking into consideration the five IS components which are: human resources, hardware, software and applications, procedures and data. These indicators allow to quantify numerically the quality level of each IS component, leading this way to a quantification of ISQ as a whole. To achieve this goal, adapted surveys were designed for every IS intervening, including a sub group of ISysQ model indicators, that belong to the expertise area of the different IS intervening. This contribution focuses on the surveys designed for external IS intervening, by relating questions, characterized by their literal significance with indicators, which have more abstract meaning. On the basis of the formulas linking questions to indicators, the component values for each external IS intervening are determined, which provide the external perception of ISQ model. |
