Abstract

This paper presents the analysis of user satisfaction with a web-based system that enables users to calculate the value of carbon credits for landholdings based on user-defined parameters including size of landholding, monoculture species, site quality, management & perpetration etc. For the purposes of this project, User Satisfaction was evaluated using questions based on the User Information Satisfaction (UIS) surveys demonstrated to validate the DeLone and McLean (1992, 2003) model of information systems success. The items in the survey used to test the UIS for this study were modified to suit the nature of the system under investigation, that is, a public, web-based information system. This differs from most previous UIS surveys which have been primarily used to examine proprietary, in-house applications. The paper reports the structural validity of the instrument using exploratory factor analysis (EFA) and structural equation modelling (SEM).
