- Purpose – Organizations of today are becoming ever more focused on their business processes. This has resulted in an increasing interest in using best practices for business process re-engineering. Two problems arise in connection to using best practices: how to find a best practice that suits particular purposes, and how to ensure that the process from the best practice has the same nature as the process under re-engineering. The purpose of this paper is to address these issues. Design/methodology/approach – The paper suggests using business process patterns, i.e. relatively high level business process models, for making near formal comparison of business processes. The paper analyzes widespread modeling techniques to find out which of them suits the task of building patterns for comparison. Based on this analysis, the state-flow modeling technique is chosen and first steps towards formal definition of business process patterns based on this technique are suggested. Findings – A pattern is defined based on the notions of state space, goal, as a surface in the state space, and valid movements towards the goal. A thinkable procedure of constructing patterns is demonstrated on two real-life examples. A hypothetical procedure for comparing process is suggested but it still needs to be verified in practice. Originality/value – The originality of the paper is the way the patterns are formulated and the underlying model, the state-flow view of processes, upon which the patterns are founded.

- In the healthcare sector, different healthcare providers, such as home care, primary care, and hospital clinics, collaborate in order to increase values for patients, such as better health state, increased knowledge on health conditions, and increased feeling of safety. To govern and evaluate such collaboration, we need a tool to understand how different patient values are related to each other, how values are related to goals, and how values and goals are related to actions planned and carried out among healthcare providers. Thereby, we can measure, analyse and redesign existing actions in order to better achieve desirable values. Furthermore, we also need a tool for finding new innovative goals and actions that better create desirable values. In this paper, we propose such a tool, in the form of a method based on value, goal and action models. Value models depict actors and the valuable resources they exchange as well as the purpose of the resources exchanged. Using these value models as a base, we are able to systematically identify high level goals and more detailed goals, as well as actions supporting these goals. Thereby, we will attain traceability from actions, via goals and values, which the actions realise. A case study from the Swedish healthcare sector is used to ground and apply our proposed method

Tidskriftsartikel (refereegranskat)abstract
- There is a growing need for Enterprise Application Integration (EAI) technologies, which align the applications of an organisation to its business processes. Such technologies require an adequate methodological support so that well structured and easily understandable models can be constructed. In this paper, such a methodological support is proposed by introducing principles for the design, validation and presentation of process models and associated data models. By applying these principles, we obtain different views of the models, and thereby facilitate the use of common models for different stakeholders, e.g. business managers, designers and operators.

A Value and Model Driven Method for Patient Oriented KPI Design in Health Care
- 2011

Konferensbidrag (refereegranskat)abstract
- In all societies, large resources are spent on health care. However, service quality is still unsatisfactory in large parts of the health care sector. One reason for this state of affairs is the complexity of health care organisations, which make them difficult to govern. Furthermore, due to the high degree of specialisation, health care organisations often need to cooperate, which adds to the complexity. One possible way to improve the cooperation and management of health care organisations is the use of performance management, which is a management approach aiming at optimising the performance of an organisation. The main instrument in performance management is the use of Key Performance Indicators (KPI), which measure how well an organisation fulfills its goals. Designing effective KPIs is a complex and time consuming task that requires substantial efforts. Therefore, there is a need for methods that support organisations in designing KPIs. This paper proposes a value and model driven method for identifying patient oriented KPIs.

A Conceptual Model for the Construction and Maintenance of Institutional Reality
- 2022
-
Ingår i: Proceedings of the ER Forum and PhD Symposium 2022 co-located with 41st International Conference on Conceptual Modeling (ER 2022).
-
Konferensbidrag (refereegranskat)abstract
- The practice of conceptual modelling is to a large extent concerned with the representation of the social and institutional reality. Much research has been devoted to the study of the processes through which institutional reality is created by means of communicative acts. Other research has investigated the structure of the institutional reality in terms of rights, obligations, roles, positions and related notions. One topic, however, in need of further work concerns the informational and physical underpinnings of the institutional reality, which are needed not only for constructing but also for maintaining it. This paper presents a conceptual model that shows how institutional phenomena depend and build on informational and physical structures. In particular, the paper highlights the role of information registries for maintaining and upholding institutional reality over time.

Konferensbidrag (refereegranskat)abstract
- Motor disability includes the lack of sensation, movement, or coordination, and Assistive Technologies (AT) can help overcome these challenges. Motor-disabled students need different ATs and configurations depending on courses and individual needs, and some solutions can be expensive. Some affordable AT has roots in gaming but can also be used for other purposes. However, there is little research on how they can be combined to define a personalized setting. Therefore, we performed a literature review to identify challenges and solutions to support students with motor disabilities in using information systems. The result defines a framework for identifying personalized settings. The usability of the result was demonstrated by performing a self-experimentation study of the first author, who has a motor disability. The results show its utility while learning process mining using the Graphical User Interface (GUI) and code-based tools. We identified challenges in using different User Interface (UI) elements, which can be used as a guideline for designers of process mining tools as well as other information systems to support diversity.

Model-Driven Process Design : Aligning Value Networks, Enterprise Goals, Services and IT Systems
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. Business processes are the ways actors work in enterprises and collaborate in value networks, while e-processes support a flexible flow of information between IT systems and business processes. The overall goal of this thesis is to propose methods for business process and e-process design and evaluation for achieving alignment between enterprise goals and IT systems. The methods are based on model-driven approaches, using enterprise and software models. More precisely, the proposed methods can be used for designing models of business processes supporting the fulfilment of enterprise goals in the setting of a value network; for designing models of generic and reusable business processes that support the fulfilment of enterprise goals; for designing models of e-processes that support a flexible alignment of IT systems with business processes; and for evaluating the extent to which business processes are aligned with enterprise goals and IT systems. The result of the thesis can be used to support business and system designers with practical knowledge on how to align business and IT systems in order to create efficient, high-quality, flexible and innovative organisations. The research presented in this thesis has been carried out following the design science paradigm. This paradigm is characterised by the creation of new and innovative artefacts for solving general problems, and the evaluation of their benefits and drawbacks.

DIdM-EIoTD : Distributed Identity Management for Edge Internet of Things (IoT) Devices
- 2023

Ingår i: Sensors. - 1424-8220. ; 23:8

Tidskriftsartikel (refereegranskat)abstract
- The Internet of Things (IoT) paradigm aims to enhance human society and living standards with the vast deployment of smart and autonomous devices, which requires seamless collaboration. The number of connected devices increases daily, introducing identity management requirements for edge IoT devices. Due to IoT devices’ heterogeneity and resource-constrained configuration, traditional identity management systems are not feasible. As a result, identity management for IoT devices is still an open issue. Distributed Ledger Technology (DLT) and blockchain-based security solutions are becoming popular in different application domains. This paper presents a novel DLT-based distributed identity management architecture for edge IoT devices. The model can be adapted with any IoT solution for secure and trustworthy communication between devices. We have comprehensively reviewed popular consensus mechanisms used in DLT implementations and their connection to IoT research, specifically identity management for Edge IoT devices. Our proposed location-based identity management model is generic, distributed, and decentralized. The proposed model is verified using the Scyther formal verification tool for security performance measurement. SPIN model checker is employed for different state verification of our proposed model. The open-source simulation tool FobSim is used for fog and edge/user layer DTL deployment performance analysis. The results and discussion section represents how our proposed decentralized identity management solution should enhance user data privacy and secure and trustworthy communication in IoT.

Securing IoT Using Decentralized Trust Privacy and Identity Management
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Internet of Things (IoT) is a multidisciplinary area where technology meets people, enriching their quality of life with an improved working environment and efficient productivity. As the number of IoT devices increases, many new technology areas are being integrated with the IoT. IoT devices mainly connect and collaborate with central cloud servers for data management. The IoT paradigm is built upon the Internet and accesses different layers of Internet architectures. IoT devices are at the access layer of the Internet, and cloud servers are located at the top layer. The innovative use cases of IoT applications drive the requirement for quick decision-making that occurs as close to the source of information as possible. IoT devices need to be authenticated near the source for rapid request processing. Trustworthy interaction and secure communication between different entities of an IoT paradigm are crucial. A centralized cloud-based implementation of IoT solutions can be problematic for ensuring trustworthy and authenticated interactions in which quicker decision-making is involved. Additionally, privacy leakage possibilities increase with cloud-based solutions, as they involve multiparty interactions, introducing more complexity into ensuring data privacy. Due to IoT application and service heterogeneity, traditional security models are unsuitable for the IoT. There is no generic model for IoT data security and user data privacy that can facilitate trustworthy collaboration and identity management near the source.The thesis focuses on creating a generic state-of-the-art artefact for IoT security, utilizing decentralized trust, user data privacy, and localized identity management for heterogeneous IoT devices and services. The main contributions of this thesis include a novel decentralized model for secure and reliable interaction between components of the IoT paradigm, complemented by a decentralized trust management model, an edge gateway-based privacy enhancement scheme, and a decentralized identity management model with new authentication and authorization mechanisms for IoT devices where access to new resources is granted locally, and activities are recorded with context information. The proposed models are generic and can be easily adapted to real-life IoT use cases with minor amendments.
