The 14 full and 18 short papers were carefully reviewed and selected from 85 submissions.  The conference presents topics on conceptual modeling, its foundations and applications. Celebrating its 40th anniversary this year, the overall theme of ER 2021 is: Conceptual Modeling in an Age of Uncertainty.

The workshops included in this volume are:

·         BC4IS: Second International Workshop on Blockchain for Information Systems·         ISESL: Second International Workshop on Information Systems Engineering for Smarter Life·         KET4DF: 4th International Workshop on Key Enabling Technology for Digital Factories

They reflect a broad range of topics and trends ranging from blockchain technologies via digital factories, ethics, and ontologies, to the agile methods for business and information systems.

This volume constitutes the proceedings of the 9th IFIP WG 8.1 Conference on the Practice of Enterprise Modeling held in November 2016 in Skövde, Sweden. The PoEM conference series started in 2008 and aims to provide a forum sharing knowledge and experiences between the academic community and practitioners from industry and the public sector. The 18 full papers and 9 short papers accepted were carefully reviewed and selected from 54 submissions and cover topics related to information systems development, enterprise modeling, requirements engineering, and process management. In addition, the keynote by Robert Winter on “Establishing ''Architectural Thinking'' in Organizations” is also included in this volume.
