Agile enterprise architecture management (EAM) is a means to cope with the pressure for continuous architectural change in the context of short innovation cycles. However, the literature states a lack of practical EAM approaches. Therefore, this study aims at fostering the development of agile enterprise architecture frameworks (EAFs) by providing agile requirements and implementation concepts based on a literature review and an exploratory multiple-case study in three organizations of the logistics and construction tools industry. The multiple-case study's ranking by importance sets the focus on three requirements, for which implementation concepts are revealed. The gained insights make the concept and benefits of agile EAM tangible, indicate a shared understanding between the cases, and afford opportunities for future research.
