A framework for understanding the vision, goals, instruments and uses of software services
2004
Ingår i: Journal of Integrated Design & Process Science. - 1092-0617 .- 1875-8959. ; 8:1, s. 129-141
Forskningsöversikt (refereegranskat) abstract
Software services have been suggested for use in several areas such as business-to-business communication, system integration and as an enabler for virtual enterprises. However, it has not been clear if the use of services in these different areas is guided by a common vision, and if they share goals and technical background. By introducing a framework that relates the vision and goals of software services to different categories of service use, this work presents an overview of the instruments needed for the development of software services. The framework spans across four interrelated parts; the vision, goals, instruments and categories of service use. Firstly a single vision for software services is proposed. This vision is then divided into the three goals of modularity, integration and discovery. Furthermore, the high-level instruments needed to achieve each goal are presented. The use of services is classified into four categories depending on reach and extent i.e.: point wise-internal, point wise-external, infrastructure-internal and infrastructure-external use. The framework presented in this paper shows how these categories of service utilise the defined instruments. As an example of framework use, the instruments needed to create a process-centric service infrastructure for infra-enterprise use is proposed.

CBILE - A Case-Based Immersive Learning Environment
2018
Ingår i: 2018 IEEE 22nd International Enterprise Distributed Object Computing Conference Workshops. - : IEEE Computer Society. - 9781538641415 ; , s. 200-203
Konferensbidrag (refereegranskat) abstract
CBILE is an immersive environment that supports Apprenticeship Simulation (AS) - a method for teaching/learning modeling skills in university education. AS is aimed at the students acquiring not only explicitly defined syntax and semantics of modeling languages, but also skills of analyzing various types of sources for obtaining information to build a model. AS is a kind of case-based learning that presents a case to the students using multimedia sources, such as recorded interviews and web-based sources. CBILE integrates all sources, simulated as well as real, to be used in the case in one place and connects them to the project tasks. The environment uses WordPress as an underlying platform for both integration and simulation of web sources.

Reuse of Simulated Cases in Teaching Enterprise Modelling
2015
Ingår i: Advances in Conceptual Modeling. - Cham : Springer. - 9783319257464 - 9783319257471 ; , s. 337-346
Konferensbidrag (refereegranskat) abstract
Case-based teaching/learning is widely used in Information Systems (IS) education in general, and in teaching/learning modeling, in particular. A case presents to the students a real or imaginary business situation asking them to build a model of it, or showing how such model can be built. In situations where a business case is presented in a text form, reusing it as is, or with modification in the same or a different course does not constitute much of a problem. However, using textual description for presenting cases has drawbacks on its own, as it does not help the students to acquire the skills of dissecting analyzing and analyzing the reality when building a model. The latter can be better achieved when a case is presented in a multimedia form, e.g. recorded interviews, website of a company, etc. As the previous works of the same authors show, such case presentations gives the students better understanding of the essence of modeling, which is appreciated by the students. The dark side of the multimedia presentation is that such a case presentation requires more time to build compared to using a textual form, and it is not easy to change it. This paper is a preliminary inquiry into the problem of reusing of cases presented with the help of multimedia. It presents a conceptual model of the domain aimed at discussing the potential of reuse of the whole case or its parts, and concludes with considerations on reusability that need to be covered when building multimedia presentations of cases.

Simulating apprenticeship using multimedia in higher education: A case from the information systems field
2015
Ingår i: Interactive Technology and Smart Education. - 1741-5659 .- 1758-8510. ; 12:2, s. 137-154
Tidskriftsartikel (refereegranskat) abstract
Purpose – This paper aims to report on a project aimed at using simulation for improving the quality of teaching and learning modeling skills. More specifically, the project goal was to facilitate the students to acquire skills of building models of organizational structure and behavior through analysis of internal and external documents, and interviews with employees and management. An important skill that practitioners in the information systems field need to possess is the skill of modeling information systems. The main problem with acquiring modeling skills is to learn how to extract knowledge from the unstructured reality of business life. Design/methodology/approach – To achieve the goal, a solution was introduced in the form of a computerized environment utilizing multimedia to simulate a case of an apprenticeship situation. The paper gives an overview of the problem that the solution addresses, presents the solution and reports on the trial completed in a first-year undergraduate course at Stockholm University. Findings – The results of the trial indicate that using rich multimedia along with a case-based learning approach did improve the overall performance of the students. It was also shown that both students’ and the teachers’ attitudes toward the solution were positive. Originality/value – The solution presented in this paper, using computer simulation in teaching/learning by focusing on an apprenticeship situation, can be reused by other university teachers, especially in the Information Systems discipline. This solution can thus be used in teaching, system design, requirements engineering, business analysis and other courses typical for information systems.

Teaching Enterprise Modeling Based on Multi-media Simulation : A Pragmatic Approach
2015
Ingår i: E-Technologies. - Cham : Springer. - 9783319179568 - 9783319179575 ; , s. 239-254
Konferensbidrag (refereegranskat) abstract
The paper addresses the problem of how university students can acquire enterprise modeling skills so that they can build high quality models of organizational structure and behavior in practical settings after their graduation. The best way of learning such skills is apprenticeship where the students follow a modeling master in a real business case. However, in a university classroom setting this is difficult to arrange, if even possible. Therefore, the paper suggests the use of a computer-based simulation as a good approximation to apprenticeship. Moreover, it suggests a pragmatic, low-cost approach making the idea accessible even for courses with a low budget. A business case is simulated by providing the students with multi-media information sources that are usually used by system or business analysts when building models. The sources consist of recorded interviews with the stakeholders, a web-site of the enterprise under investigation, internal protocols from management meetings, results of twitter search on the company name, etc. The paper presents practical guidelines on how to build such simulation based on a trial successfully completed at the Department of Computer and System Sciences at Stockholm University.

Using the Structure of Tacit Knowing for Acquiring a Holistic View on IS Field : Digital learning, apprenticeship simulation, case based learning, knowledge management, tacit knowledge
2018
Ingår i: Proceedings of the 11th IADIS International Conference Information Systems 2018. - : IADIS Press. - 9789898533746 ; , s. 19-26
Konferensbidrag (refereegranskat) abstract
The paper considers the problem of students acquiring a holistic view on the IS discipline via a set of not explicitly connected subjects taught in disparate courses. The main idea is based on M. Polanyi's works on a structure of tacit knowing that can produce "a stereoscopic image from two separate pictures". The images that are used for creating a stereoscopic picture give different perspectives on the same reality, but they do not explicitly refer to each other, the 3-d picture is being created unconsciously by the human mind. This paper demonstrates that a connection between subjects can be created by using the same or tightly connected business cases in different courses that use case based learning combined with computer-based apprenticeship simulation. The paper discusses the main idea, the trial settings, and preliminary results.

Cyber Resilience – Fundamentals for a Definition
2015
Ingår i: New Contributions in Information Systems and Technologies. - Cham : Springer. - 9783319164854 - 9783319164861 ; , s. 311-316
Konferensbidrag (refereegranskat) abstract
This short paper examines the concept of cyber resilience from an organizational perspective. Cyber resilience is defined as “the ability to continuously deliver the intended outcome despite adverse cyber events”, and this definition is systematically described and justified. The fundamental building blocks of cyber resilience are identified and analyzed through the contrasting of cyber resilience against cybersecurity with regards to five central characteristics.

Deliverable 1.2 : Initial version of requirements specification for CDD
2013
Rapport (övrigt vetenskapligt/konstnärligt) abstract
The CaaS project will elaborate the Capability Driven Development (CDD) approach that will allow digital enterprises to exploit the notion of 'capability' as a means of both designing for services and with services. This deliverable defines an initial set of requirements for CDD. These requirements are provided by the industrial partners through exploration of their use cases. The goal of this deliverable is to identify potential benefits that the CaaS approach could bring to the use cases as well the features to be included the CDD methodology. The requirements are elicited from the use case partners during semi-structured interviews. They are documented in a form of goal models, actor models and concept models for each partner separately. Information documented in these models is used to define envisioned capabilities to be design and delivered during the project as well as to establish the scope of each use case. The use case scope definition focuses on use case goals, causes of capability delivery variability, capability delivery context, functions to be provided in the use case as well as potential capability delivery adjustments. The use case specific models are combined together to obtain a preliminary set of general requirements for CDD. These requirements show CDD goals, types of stakeholders, types of context and types of adjustments. The deliverable ends with concluding remarks about the partners’ expectations for CDD. The requirements for the use cases described in this deliverable will be further elaborated in the final requirements document deliverable D1.4 and will be iteratively refined during the use case elaboration performed in work packages WP2, WP3 and WP4.
