Large, multidivisional enterprises need corporate data of high quality in order to meet a number of strategic business requirements, such as enterprisewide process harmonization, integrated customer management or compliance. Therefore, many enterprises today are in the process of establishing Corporate Data Quality Management (CDQM), which requires an overarching CDQM strategy. This paper presents a method for the development and implementation of a CDQM strategy. On the one hand the method provides guidance to a CDQM team. On the other hand, for corporate executives the method ensures that the CDQM strategy is derived from their objectives and that their requirements are systematically taken into account and fulfilled. Besides the method itself, the paper illustrates the entire design process which encompasses, among others, focus group and expert interviews, participative case studies and a multiperspective evaluation.
