    Security Requirements Elicitation from Airline Turnaround Processes
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) MatuleviÄ?ius, Raimundas; Norta, Alex; Samarütel, Silver
    Security risk management is an important part of system development. Given that a majority of modern organizations rely heavily on information systems, security plays a big part in ensuring smooth operations of business processes. For example, many people rely on e-services offered by banks and medical establishments. Inadequate security measures in information systems have unwanted effects on an organization’s reputation and on people’s lives. This case study paper targets the secure system development problem by suggesting the application of security requirements elicitation from business processes (SREBP). This approach provides business analysts with means to elicit and introduce security requirements to business processes through the application of the security risk-oriented patterns (SRPs). These patterns help find security risk occurrences in business processes and present mitigations for these risks. At the same time, they reduce the efforts needed for risk analysis. In this paper, the authors report their experience to derive security requirements for mitigating security risks in the distributed airline turnaround systems.

    Enabling Normalized Systems in Practice - Exploring a Modeling Approach
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) De Bruyn, Peter; Mannaert, Herwig; Verelst, Jan; Huysmans, Philip
    Contemporary organizations are required to adapt to a changing environment in an agile way, which is often deemed very challenging. Normalized Systems (NS) theory attempts to build highly evolvable software systems by using systems theory as its theoretical underpinning. A modeling method which supports the identification of the NS elements, required for building NS sofware in practice, is currently missing. Therefore, the paper introduces an approach for creating both data models and processing models in the context of NS, as well as their integration. It is discussed how these models can be taken as the input for the actual creation of evolutionary prototypes by using an earlier developed supporting tool. The modeling approach and its suitability for feeding the tool are evaluated to discover their current strengths and weaknesses.

    Modeling Simultaneous Cooperation and Competition Among Enterprises
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) Pant, Vik; Yu, Eric
    Coopetition (simultaneous cooperation and competition) between organizations has emerged as a prominent and critical industrial practice that allows organizations to increase combined welfare through cooperation while maximizing individual gains through competition. The formulation and enactment of such an organizational strategy entails designing and operating information systems that maximize benefits while minimizing costs from concomitant cooperation and competition. Coopetition raises new concerns and considerations about the design of data, processes, and interfaces of information systems. Analyzing coopetition can be challenging since cooperation and competition are paradoxical social behaviors that are undergirded by contradictory logics, hypotheses, and assumptions. Therefore, the ability of decision-makers to represent and reason about coopetition in a structured and systematic manner can be beneficial as it can support their efforts to co-design organizational strategies and information systems. This paper presents insights about the initial stages of an exploratory research project that is focused on the development of a modeling framework to support representation and reasoning of interorganizational coopetitive strategies. The objectives of this paper are to outline the goals of this research project which include: (1) identifying the primary characteristics for modeling and analyzing coopetitive relationships, as well as (2) proposing artefacts for expressing and evaluating these relationships.

    Process Modeling Recommender Systems - A Generic Data Model and Its Application to a Smart Glasses-based Modeling Environment
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) Fellmann, Michael; Metzger, Dirk; Jannaber, Sven; Zarvic, Novica; Thomas, Oliver
    The manual construction of business process models is a time-consuming, error-prone task and presents an obstacle to business agility. To facilitate the construction of such models, several modeling support techniques have been suggested. However, while recommendation systems are widely used, e.g., in e-commerce, these techniques are rarely implemented in process modeling tools. The creation of such systems is a complex task since a large number of requirements and parameters have to be taken into account. In order to improve the situation, the authors have developed a data model that can serve as a backbone for the development of process modeling recommender systems (PMRS). This article outlines the systematic development of this model in a stepwise approach using established requirements and validates it against a data model that has been reverse-engineered from a real-world system. In a last step, the paper illustrates an exemplary instantiation of the data model in a Smart Glasses-based modeling environment and discusses business process agility issues. The authors expect their contribution to provide a useful starting point for designing the data perspective of process modeling recommendation features that support business agility in process-intensive environments.

    From Expert Discipline to Common Practice: A Vision and Research Agenda for Extending the Reach of Enterprise Modeling
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) Sandkuhl, Kurt; Fill, Hans-Georg; Hoppenbrouwers, Stijn; Krogstie, John; Matthes, Florian; Opdahl, Andreas; Schwabe, Gerhard; Uludag, Ömer; Winter, Robert
    The benefits of enterprise modeling (EM) and its contribution to organizational tasks are largely undisputed in business and information systems engineering. EM as a discipline has been around for several decades but is typically performed by a limited number of people in organizations with an affinity to modeling. What is captured in models is only a fragment of what ought to be captured. Thus, this research note argues that EM is far from its maximum potential. Many people develop some kind of model in their local practice without thinking about it consciously. Exploiting the potential of this “grass roots modeling� could lead to groundbreaking innovations. The aim is to investigate integration of the established practices of modeling with local practices of creating and using model-like artifacts of relevance for the overall organization. The paper develops a vision for extending the reach of EM, identifies research areas contributing to the vision and proposes elements of a future research agenda.
