Key aspects of free and open source enterprise resource planning systems
2012
Ingår i: Free and Open Source Enterprise Resource Planning: Systems and Strategies. - : IGI Global. - 9781613504864 - 1613504861 - 9781613504871 ; , s. 1-17
Bokkapitel (refereegranskat) abstract
This chapter introduces basic differences between Free/Open Source Enterprise Resources Planning systems (FOS-ERP) and Proprietary ERP (P-ERP), revisiting the previous work of Carvalho (2008). Taking into account that some years has passed and the economic downturn came, it updates key aspects of FOS-ERP under both vendor and adopter perspectives. Like its predecessor, this chapter contributes to broaden the discussion around FOS-ERP, showing that its differences from its proprietary counterpart go beyond the cost factor.

Management of Information Systems Outsourcing : Evaluation of Lessons Learned from a Boundary Spanning Perspective
2012
Ingår i: Electronic Journal of Information Systems Evaluation. - Reading, UK : Academic Publishing International. - 1566-6379. ; 15:1, s. 63-73
Tidskriftsartikel (refereegranskat) abstract
Even if outsourcing is a well-researched phenomenon, it can be stated that evaluation studies on IS outsourcing relationships are scarce. From a description of two IS outsourcing relationship cases, a set of lessons learned are presented. A boundary spanning perspective is then used when evaluating these lessons learned in the client-supplier outsourcing relationships and thereby adding a “new” theoretical perspective on outsourcing relationships. The evaluation is concluded in a set of propositions that present the boundary spanning perspective of the lessons learned. The aim of these propositions is to act as both a guiding tool for how to further develop boundary spanning roles in outsourcing relationships and to act as a base for future research on outsourcing relationships.

Empowering resilient crisis response training through purposefully designed boundary objects in a simulation-gaming exercise approach : Supporting ad-hoc team interaction
2021
Ingår i: ECCE 2021. - New York, NY : Association for Computing Machinery (ACM). - 9781450387576 ; , s. 1-6
Konferensbidrag (refereegranskat) abstract
This paper reports on experiences of creating resilience-empowering simulation-gaming exercises concerning disruptions in the payment system. The aim of the exercises was to utilize gaming-simulation as a training environment where teams of practitioners can learn to develop in-depth understanding of systemic interaction (i.e., cascading effects of disruptions) and learn how to develop collaborative resilience across many different critical infrastructures. Interaction between different stakeholders in the payment system, such as business owners, banks, municipality crisis managers are considered as the foundation for building collaborative resilience. Designing the exercises in such a way that they encourage and support such interactions are therefore seen as a primary design goal. This paper describes lessons learned from the process of conducting the 17 exercises in terms of creating a well-balance simulation and an immersive experience.

Management of Information Systems Outsourcing: Challenges and Lessons Learned
2011
Ingår i: [Host publication title missing].
Konferensbidrag (refereegranskat) abstract
To be successful in Information Systems (IS) outsourcing the necessity of better management practices has been pointed out. This research contributes to the knowledge base on management of IS outsourcing by addressing management of IS outsourcing relationships. The research describes two cases of IS outsourcing relationships that differ in type of activity outsourced, IS development versus IS maintenance and operation, and relationship composition. From the cases lessons learnt are identified which with support from IS outsourcing literature are proposed as propositions for management of IS outsourcing. It can be concluded that if the propositions, related to negotiation, communication and way of working, are adopted in an early stage they could contribute to successful IS outsourcing relationships. Another conclusion is that the IS outsourcing management approach should not differ between type of IS activity outsourced, but rather reflect the nature of the IS activity; if it is a simple or complex activity

Requirements engineering in Open Source ERP
2014
Ingår i: IADIS International Conference Information Systems 2014. - : IADIS Press. - 9789898704047 ; , s. 59-69
Konferensbidrag (refereegranskat) abstract
There is a growing interest on Open Source Enterprise Resource Planning (OS-ERP) systems among organizations today. When developing ERP systems a major problem is requirements management. Proponents of open source development often claim it has a high level of involvement from users in adopting organizations. However, comparing with proprietary ERP development it is not that clear if users are more or less involved in OS-ERP development. User involvement in ERP requirement management is problematic and it makes development a complex endeavour. One problematic area is about identifying and selecting requirements for future development. In this paper we explore how requirements engi-neering is done in the OS-ERP area. To do this, we use a theoretical base on requirements management in the ERP field from which we investigate how requirement engineering in development of four different OS-ERP systems is done. The basic question asked is: How are requirements engineering done in Open Source ERP development. From the investiga-tion we present a general picture of the requirements management process in the OS-ERP area. The main conclusion is that the requirement engineering in OS-ERP development does not differ a lot from proprietary ERP development, for example regarding end-users involvement it is found that they are not involved to the extent first expected and when comparing with proprietary ERP development a similarity regarding requirements engineering in both types of ERP development was discovered.

Mitigating Escalation of Cascading Effects of a Payment Disruption Across Other Critical Infrastructures : Lessons Learned in 15 Simulation-Games
2020
Ingår i: Critical Information Infrastructures Security. - Cham : Springer. - 9783030376697 - 9783030376703 ; , s. 110-121
Bokkapitel (refereegranskat) abstract
A disruption in one critical infrastructure can quickly lead to cascading effects in several other ones. Much research has been done to analyze dependencies between different critical infrastructures, but little is known about how to mitigate escalation and cascading effects across several critical infrastructures, i.e. how to develop collective critical infrastructure resilience. This research presents the results of 15 simulation-games where groups of 6 to 8 field experts from different sectors were challenged to collaboratively manage a disruption in the payment system that quickly affected food distribution, fuel distribution, transport, health care et cetera. Teams discussed possible strategies, which next were implemented in a computer simulation. Teams could influence the sequence of events on 4 decision points during a 10 day scenario, and play the same scenario several times to test alternative solutions. Each simulation-game session lasted a full day. Data analysis involved the recorded team discussions as well as computer simulation logs of the implemented decisions and their impacts. The results show how escalation and the severity of cascading effects largely depends on the quality of the early crisis response and not so much on the initial disruption. Also, it is shown how cross sectorial collaboration is required. Responses where groups focus too much on cascading effects in one area lead too poor overall performance for society at large. Groups tend to overbalance their mitigating strategies initially, until they arrive at a more balanced strategy that covers challenges in several different critical infrastructures from an integral perspective.

Using a mixed-methods assessment approach in a gaming-simulation environment to increase resilience
2018
Ingår i: Proceedings of the 36th European Conference on Cognitive Ergonomics (ECCE 2018). - New York, NY, USA : ACM Digital Library. - 9781450364492 ; , s. 1-4
Konferensbidrag (refereegranskat) abstract
Critical infrastructures for fuel, food, transport and the payment system become inceasingly entangled. Disruptions in the payment system can quickly lead to cascading effects and even the responses of actors in the various sectors are interrelated, which can cause escalation if the collaborative responses are not well-aligned. Our contribution to the track of Human Factors and simulation discusses how gaming-simulation can be used as a training environment where groups of practitioners can learn to develop in-depth understanding of system behaviour (i.e. cascading effects of disruptions) and learn how to develop collaborative resilience across many different critical infrastructures. More specifically, our paper focuses on the development and application of a mixed-methods assessment approach in the simulation-game. The assessment method captures qualitative as well as quantitative aspects of resilience and team-work. It can be used to assess the value of our simulation-game and to increase insight in what collective resilience actually implies.

A Simulation-Game for Resilience Assessments in a Payment System Disruption Scenario
2022
Ingår i: International Journal of Knowledge and Systems Science (IJKSS). - : IGI Global. - 1947-8208 .- 1947-8216. ; 13:1, s. 1-25
Tidskriftsartikel (refereegranskat) abstract
This paper presents a quantitative agent-based simulation model of the everyday payment system used to simulate the business and consumer consequences of loss of functionality, or disruptions of the payment system for the food and fuel retailing markets as well as the bank sector in order to address resilience. The simulation model is used in a gaming simulation approach that couples a role-playing game with the simulation model in order to provide crisis management team-training to decision-makers in a multi-organisational context. Drawing primarily on resilience engineering and crisis response, the concepts of core values, coping strategies, and resilience value networks were used to guide the design of the simulation model. The ultimate aim of this study is to explore the collaborative responses from the key actors during the disruption scenario in order to evoke and facilitate collective resilience.

Using Simulation and Digital Twins to Innovate: Are we Getting Smarter?
2021
Ingår i: Proceedings - Winter Simulation Conference. - 0891-7736. ; 2021-December
Konferensbidrag (refereegranskat) abstract
Digital Twins have recently emerged as a major new area of innovation. Digital Twins are often found at the core of 'smart' solutions that have also emerged as major areas of innovation. Modeling and Simulation (MS) approaches create a model of a real-world system that is linked to data sources and is used to simulate and predict the behavior of its real-world counterpart. On the face of it Digital Twins and MS appear to be similar, if not the same. Is this actually the case? Are the two fields really separate or is Digital Twin research re-inventing the 'MS wheel'? To investigate these relationships, in this panel we will explore some contemporary innovations with Digital Twins and discuss whether or not Digital Twins is a contemporary 'refresh' or 'rebranding' of MS or if there are exciting new synergies.
