- Enterprise modelling (EM) as a discipline has been around for several decades with a huge body of knowledge on EM in academic literature. The benefits of modelling and its contributions to organizational tasks are largely undisputed. Thus, from an inside-out perspective, EM appears to be a mature and established discipline. However, for initiating serious innovations this view is not sufficient. This position paper takes an outside-in perspective on enterprise modelling and argues that EM is far away from reaching its maximum potential. EM is typically done by a limited number of people in organizations inclined to methods and modelling. What is captured in models is only a fragment of what ought to be captured. Many people actually develop some kind of model in their local practice without thinking about it consciously. Exploiting the potential of this “grass roots modelling” could lead to groundbreaking innovations in EM. The aim is to investigate integration of the established, often systematic and formalized practices of modelling in enterprises with local practices of creating, using and communicating model-like artifacts or objects of relevance for the overall organization.

- Motivation: The requirements engineering (RE) research community is aware of the importance of performing feasibility studies before starting requirements elicitation. Unfortunately, projects still frequently fail to achieve commercial success, responsibility is often unknown, and requirements engineers may be deemed responsible for mistakes made by others. Problem: There is neither empirical evidence available from a post-mortem risk analysis for projects that performed adequate RE but commercially failed nor guidance for requirements engineers on validating a business case analysis to mitigate this risk. Principal idea: By performing a post-mortem analysis of software development projects that failed to achieve commercial success, we investigate the root causes for the failures and, in most cases, trace the causes back to business case issues. We identify risk areas and provide practical due diligence guidance to the practitioner. Contribution: This exploratory case study performs an in-depth review of a detailed post-mortem analysis of three software development projects performed over a 2.5 year period. Each of the analyzed projects failed to make the expected transition to commercialization despite using appropriate RE techniques and achieving satisfactory deliverables. The analysis identifies risk factors that the RE practitioner should consider and we provide a checklist for RE practitioners to use when checking for these risks in an antecedent business case as part of their due diligence. A low-cost commercial viability assessment technique, employing Fermi approximation, is provided to equip the RE practitioner with a risk mitigation tool in the absence of business analyst resources.

Conceptual Modeling : Proceedings
- 2015
-
Proceedings (redaktörskap) (refereegranskat)abstract
- This book constitutes the refereed proceedings of the 34th International Conference on Conceptual Modeling, ER 2015, held in Stockholm, Sweden, in October 2015. The 26 full and 19 short papers presented were carefully reviewed and selected from 131 submissions. The papers are organized in topical sections on business process and goal models, ontology-based models and ontology patterns, constraints, normalization, interoperability and integration, collaborative modeling, variability and uncertainty modeling, modeling and visualization of user generated content, schema discovery and evolution, process and text mining, domain-based modeling, data models and semantics, and applications of conceptual modeling.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We are happy to bring you this special issue of Data and Knowledge Engineering based on the 34th International Conference on Conceptual Modeling (ER 2015), which was held on 19–22 October 2015 in Stockholm, Sweden. Since 1979, when its first edition was held in Los Angeles, the ER conference has been the flagship conference series and the premier international meeting space for the Conceptual Modeling community. In 2015, the conference attracted 131 submissions from all parts of the world, 41 of which were accepted as long and short papers. The technical program also included four keynotes, nine workshops, five tutorials, a Ph.D. colloquium, a demo session, and a panel session. The conference covered a broad range of areas in conceptual modeling, from ontology-based modeling and data model semantics to conceptual modeling for big data and applications of modeling in health and social care.

reqT.org – Towards a Semi-Formal, Open and Scalable Requirements Modeling Tool
- 2013

Konferensbidrag (refereegranskat)abstract
- [Context and motivation] This research preview presents ongoing work on a free software requirements modeling tool called reqT that is developed in an educational context. [Question/problem] The work aims to engage computer science students in Requirements Engineering (RE) through a tool that captures essential RE concepts in executable code. [Principal ideas] Requirements are modeled using an internal DSL in the Scala programming language that blends natural language strings with a graph-oriented formalism. [Contribution] The metamodel of reqT and its main features are presented and modeling examples are provided together with a discussion on initial experiences from student projects, limitations and directions of further research.
