Developments of traditional value stream mapping to enhance personal and organisational system and methods competencies

This paper presents developments of traditional value stream mapping (VSM) related to enhancing system and method competencies of both individuals and organisations. Since systematic immersions in traditional VSM – a highly accepted technique for improving production systems – are necessary, this paper describes from a production research point of view approaches for systematic productivity increases, reduction of lead time and an approach to improve sustainability indicators of value streams. The introduced developments of VSM focus on the entire flow and on details, thus creating synergies for designing and improving value streams, processes and work systems both economically and ecologically. On the one hand, this paper shows how practical approaches respectively rationalisation concepts (Lean principles, VSM, Process Management, short-cyclic improvement routine, Methods-Time Measurement) are used in industry in order to manage and improve processes and value streams. On the other hand, sustainability management can be supported on shop floor with utilisation of VSM. It aims to extend the view on value streams of both researchers and practitioners in sense of system and methods competencies.

Productivity improvement in logistical work systems of the genuine parts supply chain

Within the entire value stream of spare part supply, packing is one of the main issues in the distribution system and its productivity is mainly affected by a particularly high proportion of manual work. Considering the total value stream of supplying original spare parts, picking and packaging are two of the most important activities in the distribution system and they are mainly performed by intensive manual tasks. As practice shows, the methods Value Stream Design and Methods-Time Measurement (MTM) have proven to be suitable for improvement work and consequently for increasing productivity especially in work systems with manual work. This paper shows how the process building block system “MTM logistics data” contributes to planning and specifying parameters of target-conditions of value streams. It also presents a methodical approach to support practical improvement work in logistical value streams and within their work systems.

Methodische Produktivitätssteigerung: Kombinierter Ansatz zur Produktivitätssteigerung mittels WSD und MTM in Montage- und produktionslogistischen Prozessen

Kurzfassung Sowohl beim Einsatz von Wertstromdesign (WSD) als auch von Methods-Time Measurement (MTM) steht die Steigerung der Produktivität im Zentrum der Überlegungen. Die gemeinsame Anwendung von WSD und MTM bietet Vorteile durch eine aufeinander abgestimmte Gestaltung und Verbesserung von Montage- und produktionslogistischen Aspekten am und im Umfeld von Arbeitsplätzen sowie entlang eines gesamten Wertstroms. Dieser Beitrag beschreibt die Prinzipien sowie die Vorgangsweise einer gemeinsamen Anwendung.
