Background Data-driven process analysis is an important area that relies on software support. Process variant analysis is a sort of analysis technique in which analysts compare executed process variants, a.k.a. process cohorts. This comparison can help to identify insights for improving processes. There are a few software supports to enable process...
Conference Paper
Three-decades long IS research suggests that Information Technology (IT) alignment is regarded as one of the pervasive issues among researchers and practitioners. Given the current dynamic business environment, organisations need to foresee external changes and make necessary adjustments (i.e., they need to be agile) while attempting to achieve and...
Conference Paper
Full-text available
If an Enterprise Model is to be used in the strategic decision-making, it should represent the connections between the elements of internal structure, like processes, machines, people, and the elements of the business environment, like market segments, competitors, regulators. The paper presents and discusses a modeling technique – Fractal Enterpri...
Conference Paper
Full-text available
When designing modeling languages, researchers and practitioners often take contradicting positions. While the former argue for formal soundness and precise specification, practitioners aim for more flexibility in using a modeling language, i.e., by adapting it to a specific project context. The same distinction applies to the differentiation betwe...
Conference Paper
Full-text available
While there are many tools that can depict a business process on any level of detail, there is lack of tools to depict and/or design process architectures - an interconnected set of business processes that exist or are to be introduced in an organization. The FEM toolkit bridges this gap by providing a tool for process architects to discover the pr...
Article
Full-text available
There are several ways of defining organizational identity and identity management. This article considers a less exploited one, namely, defining identity as a set of structural couplings that the organization has, and identity management as an activity aimed at maintaining these couplings. The concept of structural coupling comes from biological c...

The third activity of the method framework is Design and Develop Artefact, which creates an artefact fulfilling the requirements from the previous activity. This includes designing both the functionality and structure of the artefact. In other words, the activity can be expressed as follows: Create an artefact that addresses the explicated problem...
Chapter
It may seem that the proposed method framework is similar to the waterfall model of systems and software development. This chapter shows that this is not the case and that the framework allows for highly iterative ways of working. We introduce a distinction between temporal and logical orderings of work, where the former refers to the temporal and...
Chapter
Knowledge can be used for different purposes and can exist in different forms. This chapter introduces a classification of knowledge types based on their different purposes and identifies definitional, descriptive, explanatory, predictive, explanatory and predictive, and prescriptive knowledge. A number of knowledge forms are also discussed, based...
Chapter
As in any other kind of research, design science researchers need to address ethical issues. These relate not only to the work carried out in a research project, but also to the possible ethical and societal consequences that can follow from the use of a created artefact. This chapter starts by introducing a number of general principles for researc...

Conference Paper
Full-text available
Though Viable System Model (VSM) has been invented for several decennia ago, it is still not widely use in practice. One of the possible reasons for this is that the formal structure of an organization very rarely, or may be never corresponds to the VSM prescribed structure. This confuses novices and results in erroneous VSM models. To make VSM mor...
Chapter
Organizations constantly need to change due to their desire to improve, or due to the need to adapt to changes in the environment. The use of enterprise models could be a potential aid in this transformation process - by using models an organization can describe its business, analyze it, and design changes. For an organization, models may be import...
