In the course of globalization, complex corporate networks arise in which diverse players are involved in the value-added process. Particularly at the interfaces of the value chain, there are challenges in terms of communication and cooperation, since so far no uniform procedure for the visualization, analysis and continuous improvement of product and information flows is used. These difficulties occur both within organizations and especially across company boundaries. In particular, no internationally recognized value stream standard exists at present, which is inter alia a result of a low cooperativeness of organizations due to a lack of trust, inadequate knowledge and insufficient incentives. The inconsistent use of Value Stream Management (VSM) affects many economic sectors worldwide. These inconsistent VSM approaches lead to inefficiencies, such as rework and coordination difficulties in the case of value stream audits, which represent an avoidable waste of time, natural and financial resources. In the scientific literature, a large number of fundamental VSM approaches, modifications and further developments are available that serve as a basis for the present work. The existing VSM approaches include provisions, e.g. in terms of symbols, data boxes, associated process variables and their calculation, which are each extensive, diverse and in some cases process-specific. In contrast, complex, globally distributed value chain structures require a holistic approach for the modeling of value streams. In the context of this dissertation, a VSM draft standard will be generated by means of a comparison of existing VSM approaches. Based on four different value stream levels, a multi-stage approach for the visualization, analysis and continuous improvement of cross-company product and information flows will be developed. The present thesis thus provides the methodological basis on the way towards an internationally recognized VSM standard and demonstrates in addition the potential of efficient and targeted application of VSM in value networks. On the one hand, standardizing the VSM method will enable an improved communication and cooperation along value chains in different economic sectors. On the other hand, the holistic approach helps to identify, show and implement improvement measures across company borders and ultimately leads to a reduction or ideally to the elimination of waste from an end customer perspective. The developed approach allows organizations worldwide to assess internal as well as cross-company value streams in a structured manner, to design them flexibly and to implement them effectively in practice.

Due to globalized business operations, companies in different economic sectors are part of complex supply chain networks. Their value-added processes comprise product and information flows, e.g. with a focus on manufacturing, service or trade. Until the final product is delivered to the end customer, it needs to pass many different processes in cooperating organizations. As a result, there a lot of business-to-business (B2B) interactions with cross-enterprise transactions, often including cross-border communications and sometimes even cross-industry trades with technological and often cultural implications. Especially the interfaces of supply chain networks are prone to inefficiencies, misunderstandings and delays due to a lack of standardized B2B transactions, which leads to waste in form of rework, errors and mistakes. In addition, new customers are hard to find for the manufacturing or trading company, since potential customers are so far limited to a regional network. The advantages of extending the customer base still need to be explored by many organizations. This paper discusses the opportunities by streamlining the communication along supply chain networks in a general fashion and then describes the application in a B2B automotive retail business. A concept of a web-based trading platform, which provides a seamless service for all steps of a convenient and efficient used vehicle remarketing business, is developed. It includes all phases, like offering and price finding in a comprehensive online platform, which also covers further activities, such as logistic services, financial transactions, and a mandatory feedback loop. The suggested B2B vehicle-trading platform enables a quick turnover of each transaction, which is analyzed and optimized based on the application of cross-enterprise Value Stream Management.

In numerous sectors and industries worldwide, there is a trend towards an intercompany and often international division of value creation and related work tasks. To overcome the challenges of complex cross-enterprise supply chain networks, innovative approaches to visualize, assess and enhance value streams are sought. The StreaM method, which is described in this paper, enables a comprehensive analysis, design and planning of cross-company product and information flows on different levels of value stream detail. At the same time, the entire methodology is based on a common understanding of key symbols, parameters and calculation procedures. In addition, the use of the developed StreaM method and the associated model in a case study proves its practical applicability in an industrial setting. In further validation projects, the transfer of the “Standardized cross-enterprise Value Stream Management Method” to other industry sectors is envisaged to continuously improve energy, trade or service processes.

Purpose – In most cases, the conventional assessment of value streams is based on key performance indicators (KPIs) like the share of added value, the degree of flow or a comprehensive lead time analysis. To evaluate cross-enterprise value streams of manufacturing, business or service processes in detail, a holistic methodology is needed. The paper aims to discuss this issue. Design/methodology/approach – In this research paper, the assessment of value streams within complex cross-company networks is described. After a presentation of relevant KPIs in the fields of value stream management (VSM) and supply chain management (SCM), an approach for a cross-enterprise evaluation of value streams on different levels of detail is shown. In addition, the use of an absolute VSM evaluation, in contrast to a relative VSM assessment, is examined. Findings – Based on a uniform and well-balanced set of KPIs and other VSM and SCM parameters, a performance assessment on different levels of value stream detail is enabled. Further investigations reveal the advantages of a relative compared with an absolute VSM assessment. Research limitations/implications – In addition to a comprehensive overview of existing KPIs for a value stream assessment beyond company borders, a holistic and multi-level VSM approach is presented in this paper. In contrast to existing VSM approaches, the described method allows an evaluation and subsequent improvement of value streams within supply chain networks. Up to now, the presented approach for the assessment of cross-enterprise value streams has only been tested in specific industrial environments. In future, the proposed methodology shall also be validated for other process types like business, service or further manufacturing processes. Practical implications – The described cross-company performance measurement approach shows a high practical relevance for organizations operating in supply chain networks. Due to the integrated use of different VSM parameters, the evaluation of highly interconnected value streams across corporate boundaries is facilitated. By means of a case study, the proposed methodology is validated under real industry conditions and proves its practical applicability. Originality/value – One of the novel features of this research is the extension of the traditional VSM method with respect to a relative evaluation of value streams based on a set of significant KPIs. In addition, the allocation of these KPIs to different value stream layers and categories leads to an innovative approach for a multi-level assessment according to the needs of the specific VSM application, e.g. a more standardized use of VSM in complex supply chain networks.

This article describes how on the way towards a reliable and efficient collaboration in global supply chain networks, organizations are seeking for suitable methods and tools to enhance product and information flows. Based on the evolving Lean Manufacturing methodology in combination with the increased exploitation of ICT, new and diverse Value Stream Management (VSM) approaches are currently used. Thus, a common VSM standard is sought to analyze and visualize valuable data and to synchronize capacities and flows. In this article, the authors present a review of existing VSM approaches, patents and software solutions. Furthermore, a classification comprising four categories that serve as a basis for the ongoing VSM standard development within ISO/TC 154 and a case study of an administrative value stream are shown.

In a globalized market environment, almost all companies operate in complex supply chain networks. A high degree of product diversification in combination with rapidly changing customer needs require cross-enterprise supply chain collaboration, which causes communication problems. A way to cope with this complexity is to optimize both internal as well as external processes in a holistic manner and to define standards for interaction, collaboration and communication procedures. An established method for process analysis and optimization is Value Stream Management (VSM). Despite a variety of promising VSM approaches, there is a lack of a standardized VSM method, especially with regard to complex supply chain networks. Thus, a review of methods for process visualization and their suitability for different process types shall be discussed. A common VSM method with integrated features according to the specific needs of the applying organization will help to optimize the value creation in cross-enterprise supply chains. [less ▲]

The University of Luxembourg has recently launched its learning factory, the “Lean Manufacturing Laboratory”. With the help of this manual assembly line, students gain valuable insights in the operation of a manufacturing line as well as in buffer, waste and congestion management. Currently, one of the main research topics at the University of Luxembourg in the field of Lean Management is the further development of the method Value Stream Management (VSM). The application of VSM in the “Lean Manufacturing Laboratory” with a projected focus on industry and service sectors reveals the need for a standardized VSM approach. Thus, one of the research objectives is the development of a common VSM method accompanied by standardized software and process interfaces to ensure robust product and information flows within a company and also throughout supply chains. On the way towards a VSM method as standard, existing VSM approaches have to be investigated and validated. By a detailed comparison of existing VSM approaches, all necessary fields of action for the development of a standardized Value Stream Management approach are shown. [less ▲]
