Findings – A three-dimensional role management concept was developed describing users' rights, tasks, and positions. A discussion on how to fulfill privacy requirements yielded that a semi-automated decision making regarding the use of roles with different identities is reasonable to support users' control of their privacy when interacting with others. Research limitations/implications – The concept of flexible role management complies with the requirements of PECEs. However, a fully automated approach of rule-based information disclosure is not possible as such decisions depend on personal and situational aspects. Practical implications – Using the example of a flexible role management concept, research described in this paper demonstrates that privacy and interaction concerns can be balanced and should be considered in application design processes. Social implications – Concepts of PECEs allow respecting privacy-related attitudes and could improve the quality of service consumption. Originality/value – The paper demonstrates contrasts between collaboration and privacy attitudes and presents solutions for the integration of role management to overcome this initially supposed contradiction.},
