Information systems benefits for individuals (ISBI ) has been a key construct for the IS success model , which has evolved over the years to strengthen the theoretical foundation for the IS field . However , relatively little research has been done to explore , develop and validate the underlying theoretical dimensions for this crucial construct . Moreover , extant research related to this construct in particular , and to the IS success model in general , has been conducted in the context of individual IS application instead of the overall IS in the organization . This study fulfills four research objectives : (1 ) Develop a theory -based extended conceptualization of IS Benefits for Individuals (ISBI ) in the context of overall use of various types of IT /IS by individuals in an organization (2 ) Develop a comprehensive theory -based conceptualization for the overall IT /IS use (ISU ) (3 ) Develop and Validate the ISBI and the ISU constructs (4 ) Apply the two constructs in examining IS success . This study draws from the ERG theory (ERG stands for Existence , Relatedness , Growth ; Alderfer , 1972 ) , Job Characteristic Theory (JCT ; Hackman and Oldham , 1975 , 1976 ) and other theoretical perspectives . A theory -based WJT framework was developed which consists of three levels : Work enrichment , Job interaction , and Task performance , corresponding to the three levels of the ERG theory . The ISBI construct is developed as a formative construct that consists of these three sub -constructs , and each of which , in turn , consists of three sub -constructs based on JCT and other relevant theories . With a sample of 231 responses from business professionals , the validities of the ISBI construct were established . A partial test of the IS success model was conducted with the ISBI measure and a measure of the overall IS Use . The results indicate that ISBI mediates the relationship between IS Use and satisfaction . This finding attests to the robustness of the scale in its ability to explain why people are satisfied when using IS . In addition , the study results reveal that overall IS Use has roughly equal impacts on the three types of benefits , but the job interaction benefit has the highest impact on satisfaction , while the task performance benefits has no impact on satisfaction . Further , DSS (Decision Support Systems ) Use is found to be the most important type of IS in increasing employees' job benefit perception , while GSS (Group Support Systems ) most greatly contributes to employees' increased overall IS satisfaction . These results provide a more granulated picture of the relationship among IS Use , ISBI , and Satisfaction , in the context of the emerging IS environment which has evolved far beyond the traditional IRS (Information Reporting Systems ) and gravitated toward modern DSS and GSS .In conclusion , this study has succeeded in developing and validating theory -based multidimensional measures for ISBI , and applying it to test a part of the IS success model . Further , this study expended the context of the IS success model to the overall IS and the different types of IS it includes , rather than a single system as in previous studies . The theoretical and empirical work of this study has thus contributed significantly to the cumulated research on IS success , a critical foundation for the IS field . |
