    ABSTRACT: Verification and validation are two important processes in the software system lifecycle. Despite the importance of these processes, a recent survey has shown that testing of data warehouse systems is currently neglected. The survey participants named besides others modest budget and the lack of appropriate tools as potential reasons for this circumstance. In order to verify these reasons, the paper at hand presents an evaluation of unit testing tools suitable for data warehouse testing. To address the modest budget problem, the range of evaluation candidates is limited to no charge, open source solutions, namely AnyDbTest, BI.Quality, DbFit, DbUnit, NDbUnit, SQLUnit, TSQLUnit, and utPLSQL. The evaluation follows the IEEE 14102-2010 guidelines for evaluation and selection of computer-aided software engineering tools in order to guarantee benefits from a practioners’ as well as scientific point of view. It results in a detailed overview of how the testing tools meet criteria such as different testing functionalities. At least one tool, namely DbFit, can be identified as a promising candidate with regard to the requirements.

    ABSTRACT: Based on a literature review, the paper presents a catalog of 31 Agile BI actions suitable to increase the agility of business intelligence (BI) systems. The actions are classified by the categories ‘principles’, ‘methods’, ‘techniques’, and ‘technologies’ and by their implementation level. In addition, the actions are assigned to BI agility types, resulting in an Agile BI actions selection guide. Both artifacts provide benefits for scientists (identification of research areas) and for practitioners (implementation support).

    ABSTRACT: http://conferences.computer.org/hicss/2015/papers/7367e762.pdf http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=7070386 http://www.computer.org/csdl/proceedings/hicss/2015/7367/00/7367e762-abs.html The need to develop Business Intelligence (BI) systems which are able to react to unforeseen or volatile requirements in a given time frame results from increasingly complex and dynamic organizational environments. This adaptation capability of BI systems is usually referred to as ‘BI agility’. Although a consensus within literature exists about the demand for agile BI systems, a structured overview on how such systems can be developed is missing. Closing this research gap, the paper at hand presents a catalog of Agile BI actions which is based on a comprehensive literature review. It includes 21 assessed actions suitable to increase the agility of BI systems. Therefore the catalog provides benefits to scientists (identification of research areas) as well as practitioners (identification of sophisticated actions for implementation). It consists of the four action categories ‘principles’, ‘process models’, ‘techniques’, and ‘technologies’.

    ABSTRACT: http://aisel.aisnet.org/ecis2014/proceedings/track11/12/ http://ecis2014.eu/E-poster/files/0825-file1.pdf http://www.interdisciplinary-curriculum-development.com/ The need for interdisciplinary programs for problem-based education increases. However, there is a substantial shortage of skilled boundary-spanning students, as prominently evidenced in the field of big data analytics. To solve this problem, this paper suggests a generic interdisciplinary IS curriculum process design model. The model considers education of students with deep knowledge in more than one discipline who possess the right skills that are needed by their future employers. It is applicable to various disciplines and potential combinations of these disciplines. Based on skills representing the consensus of corresponding communities and professionals, the model allows the definition of university specific constraints which are considered in the curriculum design. Besides the process design model we have implemented a prototype for a curriculum generator which supports the generation of concrete curricula. Through our approach that is based on the design science research paradigm, we formalize the curriculum development process which allows the fast and easy design of interdisciplinary programs.

    ABSTRACT: Methods are a common artifact within design science research (DSR). In the context of a research project we faced the challenge to develop a method and a software artifact in parallel. However, existing work in DSR and method engineering does not explicitly address the simultaneous development of two interdependent artifacts. Therefore, we developed a DSR process that allows the construction of so-called software-intensive methods. It considers the interdependencies of both artifacts and optimizes common DSR processes by including early feedback cycles for intermediate results - allowing the identification of initial design weaknesses like missing or dispensable design elements, inappropriate element design and usability flaws. The process has been applied and its feasibility has been demonstrated in the research project.

    ABSTRACT: Providing analytical information to all stakeholders in a timely manner remains, in the face of current challenges, a key issue in organizations. Information logistics (IL) extends present concepts of decision support like business intelligence by focusing on enterprise-wide information supply and the exploitation of synergies. The article investigates which factors play critical roles in the success of IL strategies. An empirical study by means of a causal analysis provides evidence for significant relationships between those factors and organizational performance. The study identifies comprehensiveness, flexibility, support, communication, IT strategy orientation, business/IT partnership, and project collaboration as influencing factors for IL strategy success. Not all success factors, however, validated in related strategy research can be confirmed in the IL context.

    ABSTRACT: The domains of Business Intelligence (BI) and social media have meanwhile become significant research fields. While BI aims at supporting an organization’s decisions by providing relevant analytical data, social media is an emerging source of personal and individual knowledge, opinion, and attitudes of stakeholders. For a while, a convergence of the two domains can be observed in real-world implementations and research, resulting in concepts like social BI. Many research questions still remain open – or even worse – are not yet formulated. Therefore, the paper aims at articulating a research agenda for social BI. By means of a literature review we systematically explored previous work and developed a framework. It contrasts social media characteristics with BI design areas and is used to derive the social BI research agenda. Our results show that the integration of social media (data) into a BI system has impact on almost all BI design objects.

    ABSTRACT: Szenarien mit Blended-Learning-Charakter sind Alltag an deutschen Hochschulen: Insbesondere durch die Verbreitung von Learning-Management- Systemen, in Sachsen namentlich „OPAL“, können Lehrveranstaltungen über die Präsenzveranstaltungen hinaus in nahezu allen Fachbereichen um computergestützte Lerneinheiten ergänzt werden. Nach der Etablierung von Web Based Trainings als typische digitale Ergänzungsmodule streben einige didaktische Konzepte die verstärkte Abstimmung von Präsenz- und Onlinephase an. In der jüngeren Zeit wurde vor allem die Idee des Flipped Classroom (auch Inverted Classroom genannt) diskutiert. Hierbei wird die traditionelle Aufteilung der Lehr-Lern-Aktivitäten, bei der die Wissensvermittlung in den Präsenzveranstaltungen und die Vertiefung des Gelernten in Übungen zu Hause stattfinden, vertauscht. Stattdessen erwerben die Studierenden das nötige Wissen online und im Vorfeld der Präsenzphase, in der dann mithilfe komplexer Beispiele und unter aktiver Einbeziehung der Studierenden das Verständnis gefestigt und durch den Lehrenden unterstützt angewendet werden kann. Auch die Großveranstaltung „Grundlagen der Wirtschaftsinformatik“ (GWI) an der TU Chemnitz soll im Übungsbetrieb durch ein Flipped-Classroom-Konzept verbessert werden. Hierfür werden bestehende Aufgaben mithilfe einer Fachlandkarte und der Bewertung der jeweiligen Lehrziele zu einem Online-Materialien-Pool aufgebaut. Die Präsenzphase soll zur stärkeren Einbeziehung der Studierenden in Form eines aktiven Plenums abgehalten werden.

    ABSTRACT: Traditional decision support approaches (data warehousing or business intelligence) are limited because they focus on certain analysis techniques, user groups, or usage scenarios. This reduces their potential as integrated foundation for enterprise-wide decision support. The concept of information logistics (IL) is proposed to overcome these shortcomings. IL involves planning, implementing, and controlling cross-unit data flows and storing and providing decision-relevant data. It covers strategy, process organisation and IS implementation in an integrated manner, and focuses on enterprise-wide information delivery. In this paper, the concept of IL is presented. An action research project documents the formulation, implementation, and roll-out process of an IL framework in a large company over several years. The applicability, feasibility, and utility of the IL concept is demonstrated.

    ABSTRACT: Although managerial issues of data warehousing and business intelligence received considerable attention in recent years, the strategy process has not often been investigated. This is particularly true for the recently proposed, more holistic concept of information logistics. This paper discusses the state of the art of information logistics (IL) strategy and proposes a framework of analysis which combines supply chain oriented decomposition with functional decomposition. As a foundation for proposed strategy components, current IL strategy practices are analyzed by means of a survey. The findings show that IL strategy seems to be linked to company size, governance type (business line vs. business process), and IL organization. Supply chain oriented IL strategy components (sourcing, delivery, portfolio) gain less attention than IL solution development and maintenance strategy components.

    ABSTRACT: Viele Untersuchungen belegen den unverändert hohen Stellenwert von Business Intelligence und Data Warehousing im Unternehmen (z. B. Sommer 2007). Mittlerweile sind analytische Informationssysteme zum unverzichtbaren Bestandteil der Applikationslandschaft eines Unternehmens geworden und nehmen einen erheblichen Teil des IT-Budgets in Anspruch. Allerdings stellt sich heutzutage den Unternehmen nicht mehr primär das Problem des initialen Aufbaus analytischer Systeme; Vielmehr stehen Fragestellungen des Betriebs und der kontinuierlichen Weiterentwicklung analytischer Systeme angesichts sich ändernder Rahmenbedingungen und Anforderungen im Vordergrund. Dabei werden aber nach wie vor zwei entscheidende Aspekte vernachlässigt: Zum einen fehlt die Betonung einer umfassenden Gesamtsicht auf alle Initiativen und Projekte in diesem Umfeld anstelle einer fokussierten Partikular- oder Projektsicht, zum anderen werden solche Vorhaben oft nicht mit dem dafür eigentlich notwendigen, langen Planungs- und Investitionshorizont betrachtet.

    ABSTRACT: Process-oriented information logistics is proposed as a new paradigm aimed at supporting and improving the execution of an organizations operational processes by embedding analytic information and/or analysis capabilities into the context of process execution. The paper describes empirical research providing substantial evidence that organizations can realize benefits by adopting the concept. It furthermore provides insight into the dominant design factors and distinct realization approaches of process-oriented information logistics. This kind of information is particularly useful for the engineering of situational methods aimed at the implementation and advancement of the concept within real-world organizations.

    ABSTRACT: Die Informationslogistik ist ein wichtiger Bestandteil betrieblicher Informationssysteme. Um allerdings ihr volles Potenzial entfalten zu können, muss die Informationslogistik (IL) eng an den Erfordernissen der Fachbereiche ausgerichtet werden. Governance in der Informationslogistik kann dazu beitragen, dieses Alignment herzustellen. Der Beitrag entwickelt ausgehend von der Definition derInformationslogistik und von einer gängigen Auffassung von IT-Governance ein Verständnis von IL-Governance. Die Ausgestaltung der IL-Governance wird in aufbau- und ablauforganisatorischer Hinsicht beleuchtet und die Gestaltungsobjekte der IL-Governance werden detailliert. Eine Fallstudie zeigt am Beispiel des Energieversorgers E.ON die Umsetzung der IL-Governance in der unternehmerischen Praxis.

    ABSTRACT: Prozessorientierung ist von zunehmender Bedeutung für die Steigerung von Effektivität und Effizienz unternehmerischen Handelns. Gleichzeitig sind analytische Systeme nach wie vor eher datenzentriert positioniert es fehlt eine Integration von Business Intelligence (BI) und operativen Prozessen. Das Konzept der prozessorientierten BI verfolgt die Einbettung von Techniken und Verfahren der Datenanalyse und der Informationsbereitstellung in den Kontext der Prozessausführung. Im Beitrag wird dieses Konzept näher vorgestellt, Nutzenpotentiale aufgezeigt und die Anwendungslandschaft systematisiert bzw. mit Beispielen belegt. Grundlage bilden eine Studie und Experteninterviews mit Unternehmen aus unterschiedlichen Branchen.
