Since its establishment in 2005, Data Archiving Networked Services (DANS) has been storing and making research data in the arts and humanities and social sciences permanently accessible. To this end DANS itself develops permanent archiving services, stimulates others to follow suit, and works closely with data managers to ensure as much data as possible is made freely available for use in scientific research. Economic sustainability is a key issue for DANS. For this reason DANS initiated a research project in 2007 to have a better understanding of the costs of digital archiving. DANS adopted and adjusted two managerial models, the Balanced Scorecard (BSC) and the Activity Based Costing (ABC) model. The design of the ABC model is based on DANS activities which are categorized in five clusters: Administration, Networked Services, ICT (RD and maintenance), Data Acquisition and Archiving. The Balanced Scorecard of DANS builds on the following business perspectives: Impact, Enablers/Users, Processes and Supporters. Fifteen success factors are allocated to them. The success factors are further specified with over forty performance indicators. During this presentation we will explain how the data generated by the models can be combined and can be used as decision making instruments regarding project specific costs, funding-related decisions, and predicting expenses.
