The concept of responsibility aims at making a computing
system trustworthy for its users despite the fact that failures of IT sys-
tems 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, responsi-
bility in this sense is not considered in practical systems. We especially
investigate possibilities for integration of responsibility into component-
based 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.
