To achieve such insights, the activities to be carried out during 2010 include conducting a number of case studies, which is to end up in a large questionnaire survey. The ideas presented in this paper represent the initial foundation for this work.
To sum up, this paper has produced a better understanding of how to define the optimal data maintenance effort and of the nature of costs inflicted by poor quality data. Although these contributions are to be further elaborated on in future research, in their present form they provide a better understanding of the topic which hopefully aids companies in their data quality work.
