This problem is of growing interest as companies are realizing the undeniable impact of a better understanding of business processes (BP) on the effectiveness, consistency and transparency of their business operations. The research aims at proposing methods and tools for BP model quality measurement and improvement. We propose a semantic approach of quality exploiting domain knowledge.

Indeed, companies are realizing the undeniable impact of a better understanding and management of business processes (BP) on the effectiveness, consistency, and transparency of their business operations.In this paper we propose to support this modeling effort with an approach that uses domain knowledge to improve the semantic quality of BP models. This approach relies on domain ontologies as a mean to capture domain knowledge and on meta-modeling techniques. The main contribution of this paper is threefold: 1) the meta-models describing both a domain ontology and a BP model are described, 2) the alignment between the concepts of both meta-models is defined and illustrated, 3) a set of OCL mapping rules is provided. A simple case study illustrates the process.

The scientific problem addressed in this thesis is related to modeling and improving Business Process (BP) models quality. This problem has been of growing interest as companies are realizing the undeniable impact of a better understanding of business processes (BP) on the effectiveness, consistency and transparency of their business operations. The work consist of the proposal of methods and tools for quality measurement and improvement. We propose a semantic approach of quality based on domain knowledge.

Here, I would like to express my thanks to people who have been very helpful to me during the course of this work. First of all, I would like to thank my two supervisors, Isabelle Comyn Wattiau and Samira Si Said Cherfi for their patience, guidance, encouragement, and their advices throughout my thesis. Thank you for your confidence in me manifested in agreeing to supervise my doctoral work, for all your advices and all the time devoted in directing this research. I also would like to take the opportunity to thank all the members of the research group ISID starting with the director of the research group ISID, Prof. Jacky Akoka, as well as all the group members. My special gratitude goes to my spervisor Samira Si Said Cherfi. You were more than a supervisor, you were like a mother for me in a foreign country. Because of your patience, I learned how to be rigorous not only in my professional life but also in my personal life. You were always there for me, day, night, and even on weekends. I know that I am so lucky to have you as a supervisor. You are a role model to me both as a researcher and a person. Thank you for everything. I would like to thank Prof. Geert Poels and Prof. Herve Panetto for accepting to review my dissertation. Also many thanks to Prof. Camille Rosenthal-Sabroux, Dr. Selmin Nurcan and Dr. kathia Oliveira for accepting to be a part of jury to evaluate my work. There are a numerous people with whom I shared the best moments and to whom I am greatly indebted. Dana Azar, you were more than a friend.

We propose to support this modeling with an approach encompassing methods and tools for BP models quality measurement and improvement. In this paper we focus on semantic quality. The latter is evaluated by aligning BP model concepts with domain knowledge. The alignment is conducted thanks to meta-models. We also define validation rules for checking the completeness of BP models. A medical case study illustrates the main steps of our approach.

Indeed, business process models reflect the business processes of companies. The success of these processes has a direct and undeniable impact on business operations success. Managing them through their underlying models helps improving their effectiveness, consistency, and transparency. BP modeling aims at a better understanding of processes, allowing deciders to achieve strategic goals of the company. However, several studies from the literature showed that in experienced system analysts often produce low-level quality. This situation is partly due to lack of domain knowledge. In this paper, we propose to support this modeling effort with an approach that uses domain knowledge to improve the semantic quality of BP models. We suggest to use ontologies as a mean to capture domain knowledge and meta-modeling techniques to deal with BP models independently of languages in which they are expressed. Our contribution is threefold: (1) the meta-models describing both a domain ontology and a BP model are described, (2) the alignment between the concepts of both meta-models is defined and illustrated, (3) a set of Object Constraint Language mapping rules is provided. A simple case study illustrates the process.
