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.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this research is to examine how lean has been implemented in the geriatric care sector in a municipality in Sweden. The research focuses on implementation experiences and challenges encountered. The research method used is a case study using interviews and observations for data collection. The findings indicate that there are many advantages of lean in the geriatric care sector, such as better communication, organisation and workflow. The lean implementation worked as an eye-opener and created a situation, where the employees realised a great deal of waste in the daily operations. In addition, lean tools helped to reduce the waste. The findings also indicate that there are some challenges of lean in the geriatric care sector, such as the difficulty to create long-lasting lean commitment. A lack of follow-ups, decreasing interest from senior management and lack of a holistic view were the main issues in the case organisation.

An Evaluation of Critical Capabilities and Improvement Areas for Competitive Manufacturing in a Developed-Country Environment
- 2022
-
Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 14:11

Tidskriftsartikel (refereegranskat)abstract
- This research evaluates the critical capabilities and improvement areas for competitive manufacturing in a developed-country environment. A multiple-case-study approach is applied, consisting of three manufacturing firms located in Sweden. The case study combines both quantitative and qualitative evaluations of the critical capabilities found in the extant literature. The research reveals fifteen critical capabilities and sixteen improvement areas for competitive manufacturing in a developed-country environment. The results show that the firms develop capabilities in a cumulative manner, starting with cost and quality, continuing with time and flexibility, and finally trying to improve innovation and sustainability. To develop competitive manufacturing operations in developed counties, it is therefore vital to improve capabilities related to time, flexibility, innovation, or sustainability. Irrespective of the targeted capabilities, they must contribute to cost-efficient operations and high quality must always be maintained. The efforts to develop capabilities related to innovation and sustainability may be expensive in the short term, however they can provide better cumulative results and competitiveness in the long term.

Tidskriftsartikel (refereegranskat)abstract
- This research aims to enhance the current level of knowledge from supply chain planning (SCP) by analyzing the importance of collaboration, information exchange and a supporting information system in its successful execution. These are examined through a case study from international manufacturing company, which operates in automotive industry with its global manufacturing network. Research reveals that collaboration is a complex and important issue of SCP, and occurs simultaneously in vertical and horizontal dimensions. It is important to select strategic partners and to develop a structured work processes and routines. The main objective of collaboration is to determine common goals and objectives and to facilitate the exchange of information; these together drive the performance of a supply chain higher. A sufficient information system supporting the SCP is vital to facilitate collaboration, and information exchange between the different supply chain participants. However, currently in the case company quite many phases of SCP are completed without appropriate and integrated information systems and the process itself contains several manual phases.

Shedding Light on the Brazilian Amazon Biotrade : A Study on Sustainable Development in Native Communities
- 2022
-
Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 14:19
-
Tidskriftsartikel (refereegranskat)abstract
- The Amazon is a biodiversity hotspot. Around 90% of its territory is inhabited by native communities, who spontaneously organize themselves into groups of extractivists and small producers, relying on biodiversity as their primary means of sustenance. This paper aims to discuss how the biotrade of Amazonian biodiversity goods affects native communities with respect to environmental, social, and economic sustainability. Based on a sample of 178 native extractivists in four communities, we concluded that biotrade enabled native communities to market their products by adapting to existing conditions, considering the difficulties and the expectations of traditional residents, and contributed to the three dimensions of sustainable development.

Linking moral disengagement to supply chain practices
- 2013
-
Ingår i: World Review of Intermodal Transportation Research (WRITR). - : Inderscience Publishers. - 1749-4729 .- 1749-4737. ; 4:2/3, s. 207-225

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to identify if and how supply chain practices are linked to moral disengagement techniques and thus might cause moral decoupling (MD). The research uses a literature review and multiple case study approach to investigate this issue. The literature review links moral disengagement to supply chain practices, while the case study observes the existence of the practices, and in what supply chain configurations those practices might arise. Identified configurations that might cause MD are suppliers and external partners responsible for upstream activities, division of tasks, aggregation of materials, auction-like settings, long supply chains, production in low-cost countries, production where people are not considered as equals, and configurations made to reduce costs.

Supply chain configuration and moral disengagement
- 2013

Tidskriftsartikel (refereegranskat)abstract
- This research shows that supply chain configuration may facilitate or restrict opportunities of moral disengagement. It is proposed that a moral decoupling point is a point through which materials, information, and money may be transferred, while acting as a roadblock for moral responsibility. Decoupling points allow researchers to understand how moral responsibility is connected with supply chain configuration. By mapping and removing moral decoupling points managers can structure their supply chains to increase moral responsibility of employees and better fulfil ethical guidelines. Empirical material is two-fold in this study. Firstly we investigate media reports of four cases, where Swedish companies' moral is questioned. This is complemented with three real-life case studies from three global Swedish led textile companies.
