- Modern information systems rely on data analytics and use various data sources to steer information processing and process execution activities. Capability-driven development is a method for the design and delivery of this kind of information systems. This chapter elaborates a method extension for capability-based modeling of data ecosystems for the purpose of ensuring their resilience. The ecosystem perspective is adopted because there is a need to understand the interactions among the various parties involved in capability delivery. The ecosystem model allows to analyze the impact on reliability and other properties of data providers on capability delivery resilience. The meta-model is elaborated together with a set of rules for analyzing the ecosystem model. The model is perceived as a property graph, and the network theory is used for the analysis. The ADOxx meta-modeling platform is used to implement the modeling tool, which is integrated with a graph database, where the model analysis is performed. The method and the tool are demonstrated using an example of a winter road maintenance ecosystem.

Konferensbidrag (refereegranskat)abstract
- Information Systems (IS) of modern organizations and enterprises often rely on a network of partners’ IS to deliver the services. The resilience of this network is the necessary condition for the operation of such ISs. The Digital Business Ecosystem (DBE) theory has emerged as an approach to ensure functioning and resilience in dynamic and open networks. This paper presents three cases of analysis of resilience of DBEs. The objective of the analysis is to assess the resilience of DBEs during its design phase. During this phase, often, only structural information presented in ISs models is available. In order to assess the resilience, the DBE models are analyzed for the potential for fulfilment of typical ecosystem goals and roles. The three DBE cases analyzed are winter road maintenance, digital vaccine, and Covid-19 testing. The paper evaluates the resilience of the DBEs and formulates the practices for uncovering and strengthening it.

Tidskriftsartikel (refereegranskat)abstract
- The nature of modern organizations needs to be increasingly adaptive, since they are dealing with a constant demand to respond to stimuli derived from the dynamic environments they operate in. Changing their capabilities is a common response, and this makes capability management a vital aspect of organizational survivability. To date, there are no approaches specifically designed to address this specific situation. KYKLOS and Compass are two interlinked approaches of different complexity, a DSML and a canvas, developed to support capability change. As recently developed methods, they lacked formal demonstration and evaluation; therefore, the goal of this article is to present the demonstration and evaluation of the two approaches by their stakeholders, in particular, business and modeling experts. A case study in a Swedish company in the ERP system consulting domain that is undergoing changes in its sales and consulting capabilities related to evolving customer requirements has been used to demonstrate and evaluate the two approaches. The process consisted of two evaluation cycles. The first cycle concerned KYKLOS and used two categories of evaluators, the business experts and the modeling experts. While the modeling experts evaluated positively the method, the business experts had difficulties associated with its ease of use and adoption. This resulted in the development of Compass, which was evaluated by business experts during the second evaluation cycle. Compass was evaluated more positively in terms of the difficult aspects, but the challenge is ongoing and motivates further future research.

- Organizations are dealing with a continuous need to adapt to their dynamic environments by changing their business capabilities. KYKLOS is a recently developed modeling method aiming to provide methodological and tool support for the phenomenon of capability change in organizations. This paper reports on a case study used to demonstrate and evaluate KYKLOS. The case study has been performed in a company in the ERP system consulting domain, and the results have been used to evaluate the method using two groups of evaluators, a business user group and a group of modeling experts. The paper reports the insights and findings that validate and motivate future research about the method and the different perspectives between the two groups of evaluators.

KYKLOS - A modeling method and tool for managing changing capabilities in organizations
- 2024

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The environments within which modern organizations are operating are characterized by constantly increasing volatility and diversity, which act as a driving force that continuously presents opportunities and threats to the organizations. The result of this situation is that these environments have become so dynamic that the phenomenon of organizational change is slowly becoming the new constant, rather than being an exception as in earlier years. The challenges arising from the need to handle constant change and evolution naturally lead to changing organizational capabilities. Information systems, as one aspect of an organization, can provide efficient support for the design and analysis of capabilities, and enterprise modeling can facilitate the development of specialized methods for this task. Hitherto, a plethora of capability modeling methods exist, providing a wide spectrum of perspectives.However, the support provided for managing the phenomenon of changing organizational capabilities remains limited, since existing methods have omitted to capture the elements necessary to depict organizational capabilities in motion and the motivations triggering such transitions. In addition, managing change requires more structured approaches, which should be methodologically supported and conceptualized.The goal of this PhD thesis is to develop a capability modeling method, called KYKLOS, that can support organizational change by modeling the changing capabilities of organizations and all the relevant aspects of this phenomenon. This work followed the Design Science Research framework, and started by explicating the problem via a literature review of existing capability meta-models; this was followed by the elicitation of method requirements, drawn from both the existing literature and a case study conducted in the domain of public healthcare in Sweden. Based on these requirements, an initial meta-model was developed, which was then demonstrated using the same case study and evaluated by experts through interviews. This activity resulted in an extension to the initial version of the meta-model, which was then instantiated via a case study conducted in the domain of public arts and culture in Greece. In parallel, the compatibility of other modeling approaches was explored. An extended version of the meta-model was then converted to its final version, which was suitable for the implementation of the modeling language in a tool, using the ADOxx meta-modeling platform. Simultaneously with the development of the tool, the syntax, semantics and procedure of the modeling method were created. The complete method was demonstrated through a case study at a company providing ERP solutions and consulting in Sweden, and the results were used to evaluate the method by two groups representing the stakeholder roles.The thesis contributes towards an improved management of change in organizations through the development of a method and complementary supporting tool, with the capability perspective as the focal point for the design and analysis of organizational change.

Bokkapitel (refereegranskat)abstract
- The dynamic environments where modern businesses operate in are a source of continuous change. As a result, change has emerged as an indispensable aspect of business management and analysis. The notion of capability is an essential element in business designs; therefore, business transformation is associated with monitoring and analyzing changing capabilities. Enterprise modeling can facilitate these tasks, and even though a plethora of capability modeling approaches exists, there is a lack of a method specialized for modeling capability change. The KYKLOS method, which is introduced in this chapter as a means to address the abovementioned challenge, is the result of an ongoing Design Science project aiming to provide methodological and tool support for businesses whose capabilities undergo changes or need to do so in the future. Its purpose is not only to capture the information types that are essential to the complex capability change phenomenon but also to guide the transition of capabilities. It is complemented by a homonymous tool developed using the ADOxx metamodeling platform.

Konferensbidrag (refereegranskat)abstract
- Enterprise Modeling is a discipline that facilitates understanding and analyzing complex organizational phenomena and domains. A variety of methods and tools exist, often optimized for specific domains. KYKLOS is a domain-specific method that has been developed to model the phenomenon of changing business capabilities. It is not uncommon for such methods to be complemented by tools which facilitate the user and often enhance the method with additional technical functionalities. In this paper, the homonymous tool is presented, which has been developed using the ADOxx meta-modeling platform and complements the previously developed method.
