This book constitutes the proceedings papers of the 13th IFIP Working Conference on the Practice of Enterprise Modeling, held in Riga, Latvia, in November 2020.

Due to the COVID-19 pandemic the conference took place virtually.

This book contains the refereed proceedings of two long-running events held along with the CAiSE conference relating to the areas of enterprise, business-process and information systems modeling:

* the 23rd International Conference on Business Process Modeling, Development and Support, BPMDS 2022, and * the 27th International Conference on Exploring Modeling Methods for Systems Analysis and Development, EMMSAD 2022.

The conferences were taking place in Leuven, Belgium during June 6-7, 2022.

For BPMDS 7 full papers and 2 short papers were carefully reviewed and selected for publication from a total of 18 submissions; for EMMSAD 11 full papers and 3 short papers were accepted from 30 submissions after thorough reviews.

The papers were organized in topical sections as follows:

BPMDS: Actual and perceived challenges; business process modeling; understanding collaboration: one issue, many perspectives; and event logs – why it derivates;

EMMSAD: Foundations of modeling and method engineering; enterprise, business process, and capability modeling; information systems and requirements modeling; domain-specific and knowledge modeling; and evaluation of modeling approaches.

* the 24th International Conference on Business Process Modeling, Development and Support, BPMDS 2023, and * the 28th International Conference on Exploring Modeling Methods for Systems Analysis and Development, EMMSAD 2023.

The conferences were taking place in Zaragoza, Spain, during June 12-13, 2023.

For BPMDS 9 full papers and 2 short papers were carefully reviewed and selected for publication from a total of 26 submissions; for EMMSAD 9 full papers and 3 short papers were accepted from 26 submissions after thorough reviews.

The BPMDS papers deal with a broad range of theoretical and applications-based research in business process modeling, development and support. EMMSAD focusses on modeling methods for systems analysis and development.
