TOWARDS A CONSOLIDATED RESEARCH MODEL FOR UNDERSTANDING BUSINESS INTELLIGENCE SUCCESS
Research about the factors that determine the success of information systems (IS) suggests that IS success is an elusive phenomenon that can only be explained in terms of a multi-dimensional construct. Despite the usefulness and unique qualities of Business Intelligence (BI) solutions, the factors responsible for the success of BI solutions remain poorly understood. Our article attempts to illuminate a path towards a clearer understanding of how BI solutions succeed by drawing on the existing body of literature and critically reflecting on the updated model of information systems success presented by DeLone and McLean (2003) and Wixom and Watson’s (2001) model of data warehousing success. The principal research contribution consists of expanding, adapting, and synthesising these two models into a consolidated model for BI success. We derive a second order model, delineate its constructs, and conceptualise their relationships based on prior research related to IS success. The operationalization of these factors has the potential of leading to a more precise instrument for understanding, evaluating and analysing the success of BI solutions
Towards Principles for Structuring and Managing Very Large Semantic Multidimensional Data Models
The management of semantic multidimensional data models plays an important role during the phases of development and maintenance of data warehouse systems. Unfortunately, this is not done with the necessary stress by now. Reasons might be seen in the plethora of semantic notations or the insufficient tool support for multidimensional modeling. The paper on hand provides experiences gained within a project with an industry partner of the telecommunications industry. Their problem is a very huge data warehouse with more than 400 data cubes and several hundred key performance indicators. We developed a repository-based solution for managing the semantic data models. Our lessons learned show that especially for very large data models there has to be a repository based solution as well as a clear concept on how to break them up into their component pars. The aim of our principles is to increase the understandability as well as the maintainability of semantic multidimensional data models
Computer-Aided Warehouse Engineering (CAWE): Leveraging MDA and ADM for the Development of Data Warehouses
During the last decade, data warehousing has reached a high maturity and is a well-accepted technology in decision support systems. Nevertheless, development and maintenance are still tedious tasks since the systems grow over time and complex architectures have been established. The paper at hand adopts the concepts of Model Driven Architecture (MDA) and Architecture Driven Modernization (ADM) taken from the software engineering discipline to the data warehousing discipline. We show the works already available, outline further research directions and give hints for implementation of Computer-Aided Warehouse Engineering systems
Towards a Life Cycle Oriented Business Intelligence Success Model
Information System (IS) success has been an essential research issue in the IS community for nearly two generations of IS researchers. For the Business Intelligence (BI) domain we see the lack of a comprehensive, life cycle oriented success model. Based on an extensive review of BI success related literature, we propose a methodology for creating such success models in general and demonstrate the feasibility of the proposed approach within the context of BI. A life cycle oriented BI success model is presented including an outline of the constructs, their relationships, and associated measurement items. From a practical perspective, the results provide assistance for the future development of BI solutions in organizations. The paper deepens the understanding of success model adaptation and extension from a theoretical perspective
A Business Intelligence Perspective on the Future Internet
Business Intelligence aims at providing decision support based on available information and tailored to the recipient‟s context due to the level of aggregation and form of delivery. The future internet will dramatically broaden both the spectrum of available information and the user‟s possible contexts. Further, we do not only expect a quantitative dart but a qualitative switch which will require the application of new methods and paradigms. This paper‟s aim is to systematically analyse implications of the future internet on Business Intelligence in order to identify possible perspectives, chances and risks for BI and vice versa by summarizing and categorizing current research
Benefits and Challenges of Business Intelligence Adoption in Small and Medium-Sized Enterprises
Leveraging information is a key success factor for companies. Over the last two decades BusinessIntelligence (BI) has evolved to become a foundational cornerstone of enterprise decision support.However, prior research shows that small and medium-sized enterprises (SMEs), in particular, lagbehind in the proliferation of BI. In this exploratory study we examine BI adoption within GermanSMEs in the state of Saxony (n = 214). We explore perceived benefits and challenges in their efforts toimplement BI. By applying cluster analysis to these results we suggest four types of BI SMEs, eachwith an individual profile concerning potential benefits as well as a certain set of challenges that areto be expected when it comes to adopting BI solutions. Results can create value for enterprises thatplan to implement a BI solution, BI consultants as well as BI suppliers
Shaping the Next Incarnation of Business Intelligence - Towards a Flexibly Governed Network of Information Integration and Analysis Capabilities
The body of knowledge generated by Business Intelligence (BI) research is constantly extended by a stream of heterogeneous technological and or- ganizational innovations. This paper shows how these can be bundled to a new vision for BI that is aligned with new requirements coming from socio- technical macro trends. The building blocks of the vision come from five research strings that have been ex- tracted from an extensive literature re- view: BI and Business Process Man- agement, BI across enterprise borders, new approaches of dealing with un- structured data, agile and user-driven BI, and new concepts for BI gover- nance. The macro trend of the diffu- sion of cyber-physical systems is used to illustrate the argumentation. The realization of this vision comes with an array of open research ques- tions and requires the coordination of research initiatives from a variety of dis- ciplines. Due to the embedded nature of the addressed topics within gen- eral research areas of the Information Systems (IS) discipline and the linking pins that come with the underlying Dynamic Capabilities Approach such research provides a contribution to IS
Metadatenmanagement in der Business Intelligence - eine empirische Untersuchung unter BerĂĽcksichtigung der Stakeholder-Perspektiven
Im Zuge stetig steigender Komplexität in Business-Intelligence-Systemen nimmt auch die Bedeutung des Metadatenmanagements (MDM) kontinuierlich zu. Die vorliegende Studie untersucht den Status Quo des MDM in der Business Intelligence (BI) aus Sicht der drei BI-Stakeholder-Typen Endanwender, Entwickler und Entscheider. Die Ergebnisse veranschaulichen, in welchen Anwendungsgebieten des MDM derzeit Handlungsbedarf gesehen und wo die größten Herausforderungen für die Weiterentwicklung verortet werden. Bei den befragten BI-Stakeholder-Typen zeigen sich Abweichungen in der Bewertung der Anwendung des MDM in der BI-Entwicklung, im BI-Betrieb und in der organisatorischen Einbettung. Die differenzierte Analyse der Wahrnehmungen der drei Stakeholder-Typen liefert insbesondere BI-Entscheidern Anhaltspunkte für Priorisierungsentscheidungen unter Berücksichtigung der divergierenden Fach- und IT-Perspektiven
