Evaluating perceived and estimated data quality for Web 2.0 applications: a gap analysis

摘要

To increase user satisfaction and enhance a positive image, the quality of software needs to be continuously improved. This study empirically investigates the importance of 15 quality characteristics and evaluates how well the Web 2.0 applications perform on those characteristics from a data quality perspective. Based on questionnaire responses from 279 participants and the results of importance-performance analysis, the performance of all data quality characteristics was found to be below the end user expectation. Confidentiality showed the greatest discrepancy between importance and performance.
