Although succession management can be supported through DSS, the final decision regarding succession candidates is made by managers and HR professionals within conferences. In practice, conferences are supported by paper-based information about employees, positions, and development measures. This approach has two major drawbacks: First, additional effort is needed, as all information must be prepared prior to conference. Second, additional information isn't available, if previously unconsidered candidates were suggested so that decisions are based on incomplete information. Our goal is to address these problems by developing a mobile application for tablet PCs which supports succession decisions by distributing necessary information. We identify requirements for such applications based on theoretical and practical insights, which we transform into design principles. Finally, these principles inform the construction of an instantiation that can support succession conferences.
