The concept of responsibility aims at making a computing system trustworthy for its users despite the fact that failures of IT systems cannot be completely excluded. The presented concept comprises the following issues: In case of failures, the responsible stakeholder can be identified and it is ensured that this stakeholder is willing to compensate arisen loss. This enables users to claim damages. Until now, responsibility in this sense is not considered in practical systems. We especially investigate possibilities for integration of responsibility into componentbased systems whereas the interests of all involved stakeholders should be considered. The newly introduced concept of tailored responsibility enables users to pose flexible demands for responsibility.
