User Perception Of The U.S. Open Government Data Success Factors, Joy Alatta

Walden Dissertations and Doctoral Studies

This quantitative correlational study used the information systems success model to examine the relationship between the U.S. federal departments' open data users' perception of the system quality, perception of information quality, perception of service quality, and the intent to use open data from U.S. federal departments. A pre-existing information system success model survey instrument was used to collect data from 122 open data users. The result of the standard multiple linear regression was statistically significant to predict the intent to use the U.S. open government data F(3,99) = 6479.916, p <0.01 and accounted for 99% of the variance in the intent to use the U.S. open government data (R²= .995), adjusted R²= .995. The interdependent nature of information quality, system quality, and service quality may have contributed to the value of the R². Cronbach's alpha for this study is α=.99, and the value could be attributed to the fact that users of open data are not necessarily technical oriented, and were not able to distinguish the differences between the meanings of the variables. The result of this study confirmed that there is a relationship between the user's perception of the system quality, perception of information quality, perception of service quality, and the intent to use open data from U.S. federal departments. The findings from this study might contribute to positive social change by enabling the solving of problems in the healthcare, education, energy sector, research community, digitization, and preservation of e-government activities. Using study, the results of this study, IT software engineers in the US federal departments, may be able to improve the gathering of user specifications and requirements in information system design.
