PURCHASING PRODUCT-SERVICE BUNDLES IN VALUE NETWORKS - EXPLORING THE ROLE OF SCOR

The implementation of electronic procurement processes for product-service bundles, consisting of product- and service components requires a consideration of strategic, tactical and operational procurement and information and communication technologies in value networks. In the past, the scientific discussion oriented on traditional procurement processes for products and technology-solutions. Increasingly, the design of hybrid procurement processes in value networks is of scientific interest. The combination of different procurement processes for products and services, however, includes problems. This paper shows the need for a process-oriented approach in procurement at several abstraction levels. We describe a model for the design of the electronic procurement process in value networks to serve product-service bundles. Different process characteristics are investigated for the applicability of product-service bundles and SCOR. We adjust a proposal for the procurement process in value networks

PURCHASING CLOUD-BASED PRODUCT-SERVICE BUNDLES IN VALUE NETWORKS - THE ROLE OF MANAGEABLE WORKLOADS

The implementation of electronic procurement processes for product-service systems, consisting of material and service components requires a consideration of strategic, tactical and operational issues in procurement processes and information technologies. Increasingly, in certain industries, these product-service systems consist more and more of cloud-based components like online storage or web applications. In the past, the alignment of business processes with a focus on traditional procurement processes for products or services has been well established. But with the rise of product-service systems as core offering from companies, the design of hybrid procurement processes in value networks has to be developed. The merging of different procurement processes for products and services, however, has severe problems and does not reflect the specific requirements in the procurement of product-service systems, especially with cloud-based components. This article highlights the need for a process-oriented view in procurement at multiple levels of abstraction and describes a model for the design of electronic procurement process in value networks for cloud-based product-service systems requirements. Different process characteristics are examined for applicability to hybrid value performance and allow an adjustment proposal for the hybrid procurement process. The proposed procurement model is validated in a typical case-study in the IT industry

Recommender Systems for Strategic Procurement in Value Networks

The implementation of recommender systems in electronic procurement processes for service packages, consisting of product- and service components requires a consideration of strategic, tactical and operational procurement as well as information and communication technologies in value networks. Increasingly, the design of recommender systems for procurement processes in value networks is of scientific interest. The combination of different procurement processes for products and services driven by recommender systems however, includes problems. This paper shows the need for a process-oriented approach in procurement at several abstraction levels. A model for the design of the electronic procurement process in value networks to serve the identification of complex service packages and suppliers with recommender systems is described. Different process characteristics are investigated for the applicability of recommender systems in e-procurement. As an artifact this approach adjust a proposal for the recommender system-based procurement process in value networks

On the usage of theories in the field of Wirtschaftsinformatik : a quantitative literature analysis

The development of theories is a central goal of every scientific discipline. Hence, theory development is also of considerable importance to the field of Wirtschaftsinformatik (WI), which seeks to progress as a scientific discipline. WI is the discipline focussing on research and design of information systems conducted by the German-speaking community. WI has slightly different objectives, focusses on different methods and different desired results compared to the Anglo-American Information Systems (IS) research discipline. Although both disciplines deal with information systems as their main research object, Mertens et al. (2014) propose to consider both disciplines as halfsister disciplines (in German: Halbschwesterdisziplinen). Against the background of the growing importance of theory development in WI, a lot of WI research contributions use and reference existing theories and theoretical models for different purposes, e.g. to derive and test hypotheses or to justify design decisions in the context of information systems’ design and development. Often, these theories originate from related scientific disciplines like economics or psychology. However, as it is still not clear which theories are of particular importance to WI research, this report aims at presenting a detailed analysis of the current usage of theories in WI and addresses the following research questions: Which theories are used in WI research and where do they originate from? and How has the usage of theories developed over time? These questions were examined based on a systematic analysis of a broad amount of scientific literature. Thus, this report is supposed to make a contribution to the ongoing discussion on the theoretical foundations of WI. Our analysis shows that 1,160 WI articles from 2000 to 2011 do, in large part, reference the same theories as Anglo-American Information Systems (IS) research. These findings are discussed and implications are highlighted
