Measuring the Success of Social Information Systems: an Assessment of Past Contributions and a Guide for Future Research.

With the explosion of social media systems and collaborative social networks has come the challenge to evaluate whether new measures of information systems success are needed. Social Information Systems are charactersied by distinctly new features and by the changing role of system users. Many of the traditional measures of information systems success may not fully capture the range of experiences and impacts inherent with this unique class of information systems. This study presents a structured literature review to identify Social Information Systems measures found in previous studies. The DeLone and McLean Information System Success Model is then used to organise and analyse existing measures of Social Information Systems across the six dimensions of the IS Success Model: System Quality, Information Quality, Service Quality, Use, User Satisfaction, and Net Social Impacts. Research gaps are identified in terms of insufficient, missing, and needed measures. New measures are then proposed based on the theoretical concepts related to Sociability, Trust, Enjoyment, and "Regimes of Value". Finally, this study recommends an agenda for future research for measuring Social Information Systems success.
