Factors affecting global supply chain design
- 2012
-
Konferensbidrag (refereegranskat)abstract
- Due to the limited existing knowledge pertaining to the factors which govern localization of operations and capabilities in a global supply chain, the purpose of the paper is to find out which factors and how they jointly affect the design of global supply chains. The relevant literature is reviewed and a concept matrix is developed. Five companies were selected in order to illustrate the issues of global supply chain design. Among them, three companies are considered to have efficient supply chain and less complex products, while the two others are considered to have responsive supply chain and more complex products. The issues discussed with the selected companies cover global sourcing, challenges, technological advancement and issues related to management control. The study identifies about fifty factors that affect global supply chain design, and specifically how theses relate to design decisions on location of factories and production, supplier selection and development, distribution of products and organisation of interfaces along the supply chain. The discrepancies between theory and practice as well as the implications for further research are discussed.

Konferensbidrag (refereegranskat)abstract
- In certain situations, global companies strive to take advantage of short-term changes in economic and exchange rates on the never-ending journey of competitiveness. This paper seeks to extend Ferdows’s (2008) production network models by adding the factors affecting shifts between rooted and footloose network configurations. Two companies were selected in order to illustrate the models and reveal other possible factors. The identified factors are differentiated in terms of configuration and coordination and merged in a matrix. The trends and implications on global supply chains are also discussed.

Global supply chain design : Building a decision model
- 2012
-
Konferensbidrag (refereegranskat)abstract
- The knowledge pertaining to the factors, which govern localization of operations and capabilities in a global supply chain, is limited. The purpose of the paper is to find out which factors and how they jointly affect the design of a global supply chain. The relevant literature is reviewed and a concept matrix is developed. The study identifies 30 factors that affect a global supply chain design and specifically how theses relate to the design decisions on location of factories and production, supplier selection and development, distribution logistics, organisation of interfaces/enterprise information infrastructure along the supply chain and human resource development. The decision model is developed and the description of the model is done with the help of an example (location of a factory) by using the Analytical Hierarchy Process (AHP) (Saaty, 1990).

Global Supply Chain Design : Exploring configurational and coordination factors
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis addresses the topic of global supply chain design. One major challenge concerns how to manage the tension between separation and integration pertaining to the localization of business activities. In this regard Ferdows (2008) worked to create two new production network models (rooted production network and footloose production network). Earlier studies have highlighted the choices that are involved in the network of facilities but lack in providing a comprehensive picture in terms of both configurational and coordination factors that govern the design of global supply chain. There is a need for a conceptual model where factors affecting the design process of a global supply chain can be applied. Two main research questions have been addressed in this study. First, exploring and identifying the factors affecting global supply chain design. Second, investigating the factors that influence the position on the spectrum of rooted and footloose supply chain design. A literature review analysis and multi-case studies have been performed for this study in order to explore the factors. The companies were selected in order to reflect upon the two types of network, i.e., rooted and footloose. The primary data were selected through interviews with the managers.This study highlighted that there are many factors that affect configurational and coordination decision areas within a global supply chain. This study categorized the factors and the configurational/coordination decision areas with two main competitive priorities, i.e., cost and differentiation in the form of a “conceptual model.” The study also highlighted the factors in a matrix, which showed their position on the spectrum of rooted and footloose network configurations. For instance, the coordination factors that drive towards a footloose network include: high orchestration capabilities, need access to new technology and knowledge, proximity to suppliers, etc. The configurational factors that drive towards a rooted network include: economic stability, proximity to market, concerns for sustainability issues, high transportation cost, need for high proximity between key functions, need for intellectual property rights protection, etc.

Digital Waste – misjudged element of value stream in lean manufacturing
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The increasing prevalence of digital technologies in manufacturing is aimed at enhancing and streamlining traditional lean processes. However, the rapid automation of manufacturing brings about challenges due to a limited understanding of production waste mechanisms by practitioners. There is growing concern about the potential emergence of digital waste as a result of the influence of digital technologies on lean manufacturing. This thesis aims to examine the role of digital waste within the overall waste in digitalized lean manufacturing, as well as the impact of technologies on lean waste and practices.The thesis is driven by three research questions and comprises five papers that stem from five individual studies. The initial study explores the potential classification of uncollected and unprocessed data as a novel manifestation of Muda, or digital waste. The subsequent study seeks to assess the capability of implementing ERP at a supply chain level to amplify latent lean efficiencies within entities. Lastly, the third study delves into the perceived impacts of soft management practices, employee behaviors, the integration of digital technologies in manufacturing facilities, and their connection to the emergence of digital waste. The fourth study delves into the digital waste generated by companies with automated lean practices, while the fifth study explores the factors contributing to digital waste within the European manufacturing sector.The findings uncover the existence of a novel type of waste, known as digital waste, which may originate from either the product itself or the production process. The findings reveal that the use of ERP technology has a significant impact on identifying hidden lean potential across three categories: unlocked hidden lean potential in an unconnected ERP system, unlocked hidden lean potential in a connected ERP system, and hidden lean potential in a shared ERP system. Furthermore, the study indicates that various aspects such as top management leadership, middle management involvement, employee education, corporate social responsibility focus, innovation, knowledge sharing, work-family balance, psychological capital, job satisfaction, and career commitment, which fall under soft lean management practices, are positively influenced by the digital transformation process. Conversely, soft lean management practices, such as employee training, creativity, discretionary effort, turnover intention, and proactivity, appear to be negatively impacted by digital transformation. Additionally, the final results suggest the existence of digital waste in supplier-related lean practices (specifically, automated JIT delivery) within product-oriented and service-oriented technologies, as well as in internally related lean practices (specifically, automated set-up) within process-oriented technologies. Furthermore, evidence of digital waste is observed in customer-related lean practices, particularly those involving digitally engaged customers, across product-, service-, and process-oriented technologies. Finally, the study reveals that a majority of European manufacturers collect and process data for multiple purposes.The research presented in this thesis adds significant value to the ongoing discourse surrounding lean waste by engaging in a theoretical discussion of both physical and digital waste in the context of technological advancements. This thesis contributes to the discourse surrounding the automation of lean methodologies across product, process, and system domains, while also examining the influence of digital transformation on lean management practices. Furthermore, it investigates the role and consequences of Enterprise Resource Planning (ERP) systems in lean production. In practical terms, the thesis validates the presence of a novel type of waste that can impact the cost management of manufactured products, fosters transparency for digital collaboration, and advocates for increased investment in technologies and specialized personnel to offer analytical services in conjunction with manufacturing products.

Lean Implementation : the significance of people and dualism
- 2013
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Lean, with its origins at the Toyota Motor Company, is a concept that is known to increase effectiveness in manufacturing. The Lean concept is now argued to be relevant not only in manufacturing but in service and health-care delivery as well. The reported results of Lean implementation efforts are divided. There are reports that most of the Lean implementation efforts are not reaching the goal; on the other hand, there are reports of promising results. The divided results from Lean implementation efforts show how important it is to research and identify factors that are barriers to successful implementation of Lean. This thesis aims to contribute knowledge about barriers to Lean implementation by collecting empirical findings from manufacturing and health care and structuring the perceived barriers and difficulties to Lean implementation. My first study aimed to compare similarities and divergences in barriers to Lean described by key informants in manufacturing and health care. The data was collected via semi-structured interviews. Findings showed that the perceived difficulties and barriers are much the same in manufacturing and health care. The second study was a case study at a manufacturing firm, researching how the views on Lean of the managers implementing Lean influence its implementation. Data was collected via semi-structured interviews with 20 individuals and covered all hierarchical management levels in the company. Findings showed that managers' views on Lean influence the implementation but also that learning during the implementation process can alter managers' views of Lean. The third study aimed to research how management of Lean is described in the literature. This was done through a literature review. The findings showed that Lean management is a matter of dualism, consisting of two complementary systems of action, management and leadership, which are related to the two basic principles of Lean, continuous improvement and respect for the people.
