EXAMINING INFORMATION SYSTEM’S USAGE AND PERFORMANCE INDICATORS USING TECHNOLOGY UTILIZATION, SATISFACTION AND PERFORMANCE

ABSTRACT:
While the development of information systems in workplaces with the aim of achieving costeffectiveness, efficiency and quality of service delivery remain sacrosanct, issues of effective utilization and its resultant implications on organizational performance remain critical from one context to another. Unfortunately, few studies had considered focusing on these causal relationships among information system deployments in the construction industry especially in developing countries like Nigeria. This work modelled the interactions causal relationships associated with task technology fit, system usage and performance variables using the TUSPEM model. Through convenience and stratified sampling techniques, the views of 136 senior staff including top level management staff, sectional heads and other senior staff of a construction firm in Nigeria were sought. Smart PLS structural equation modeling software was used for the analysis of the dataset. The result showed significant relationships between causal variables in the TUSPEM model such as Application utilization to performance (t-value 2.44, P< 0.02), utilization to user satisfaction (t-value 2.87, P<0.01).

TTF to performance (t-value 2.86, P<0.06), satisfaction (t-value 4.40, P<0.00), User attitude to utilization (t-value 5.40, P<0.00). Computer 2self-efficacy to utilization (t-value 4.47, P<0.00). User satisfaction to performance (t-value 2.47, P<0.01). Critical appraisal and integration of quality feedback on information system usage and its resultant effects on the numerous information systems being deployed must not be sideline if the sustainability of information system is anything to go by. Other implications are discussed.
