Segmentation and differentiation in defence supply chain design : A dynamic purchasing portfolio model for defence procurement
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- An important priority in the current Swedish Defence Bill is to increase the operational warfighting capability of the Swedish Armed Forces, which has implications for the defence supply chain. A recent study suggested that the Swedish Armed Forces should use segmentation of supplies and differentiation of supply chains to enable an affordable supply chain design (SCD). This raises questions regarding which segmentation model and which supply chain strategies (SCSs) the Swedish Armed Forces should use.The purpose of this research is to design and develop a purchasing portfolio model (PPM) for defence procurement, which will be of practical use for defence authorities. The author defines a PPM as consisting of a segmentation model, tactical levers, differentiation strategies and guidance for management decisions. The research builds on a Delphi study with twenty experts from Swedish defence authorities. It addresses the operational requirements on readiness and sustainability that must be satisfied, as well as research gaps and open issues in the literature regarding PPM design and application.The findings include several novelties. The author proposes a dynamic PPM, including an innovative two-stage segmentation model, with a precursor and a two-dimensional model. The latter merges sixteen elements into one square and three other segments. Another originality is that the PPM is both prescriptive and serves as a catalyst for in-depth discussions. The author also develops guidance for management decisions, including twelve tactical levers, and eight SCSs to differentiate treatment of the supply segments.The research contributes to theory by combining constructs from the purchasing and supply management (PSM) literature and supply chain management (SCM) literature, and applying them in the context of military logistics, including defence procurement. It contributes to practice by developing a PPM that is relevant to practitioners in defence procurement and satisfies the operational requirements of the Swedish Armed Forces. It also contributes to methodology by investigating how researchers can use two panels in Delphi studies to enhance research validity.

Sourcing strategising in the new product development process : Insights from the strategy-as-practice lens and engineer-to-order context
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In many cases, manufacturers have changed from sourcing only a few, simple, and separate components from local suppliers to sourcing a high variety of modules from globally dispersed suppliers. This has resulted in the implementation of a wide variety of sourcing strategies, including, for example, multiple sourcing and supplier integration. All these and other sourcing strategies are aimed at achieving a certain level of supply chain (SC) responsiveness. The level of SC responsiveness ideally matches the characteristics of a product. For example, highly innovative products typically require highly responsive SCs.In order to match products with their SCs, manufacturers are advised to engage in sourcing strategy in their new product development (NPD) process. However, there are at least two knowledge gaps in the literature on this topic: (1) the lack of a widely accepted, comprehensive conceptualisation of how manufacturers can engage in sourcing strategy in NPD, and (2) the lack of empirical insights into manufacturers operating in the engineer-to-order (ETO) context. This dissertation focuses on filling these knowledge gaps.Addressing the first gap, the dissertation uses the theoretical lens of ‘strategy-as-practice’ (SAP) and the literature to conceptualise the ‘doing of sourcing strategy’ in NPD as three interrelated dimensions: (1) practitioners, (2) activities, and (3) practices. Through discussing these dimensions and their potential interplay throughout NPD, the dissertation demonstrates the potential of the SAP lens in providing a common framework and reducing the fragmented nature of the literature. By using the SAP lens, the dissertation also contributes to practice. Despite not being ‘actionable’ in the sense of constituting detailed guidelines for acting, the SAP lens produces insights that can help practitioners to become more reflective. For example, they can learn to see sourcing strategising as a multidimensional, dynamic concept and the place it can occupy in the NPD process.The second knowledge gap in the literature regards the lack of empirical research focusing on the ETO context. Therefore, the dissertation includes a case study focusing on practitioners’ sourcing strategising activities and practices in this context. First, five approaches to performing sourcing strategising activities in NPD are explored in terms of their conditions and intended outcomes. Secondly, four practices that can support sourcing strategising in NPD are identified. These practices – referred to as ‘Design for Supply Chain’ (DFSC) practices – are also examined in terms of their interrelations. Practitioners can use the case study findings to compare the advantages of the five sourcing strategising approaches when sourcing items or services. Furthermore, the findings allow practitioners to assess how the four interrelated DFSC practices can support their sourcing strategising efforts in NPD.

Towards System Supply : Development of Small and Medium-Sized Contract Manufacturers
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- One way for a small subcontractor to meet increasing global competition is to develop a system supplying ability, implying a transition in the supply chain toward a larger overall responsibility. As large corporations outsource parts of their manufacturing and services, many small and medium-sized enterprise (SME) suppliers are expected to deepen their capabilities and take on the role of system suppliers. The overall purpose of this thesis is to advance the understanding of how SME contract manufacturers can develop such capabilities, identifying demands and abilities in various steps of this process. The research approach is based on the resource-based view.This longitudinal case study of an SME supplier striving to become a system supplier covers the period from 2006 to 2014. The researcher’s role as business developer and member of the management made it possible to follow the company's development continuously and closely, providing access to relevant internal data complemented with internal and external semi structured interviews and focus discussions. The longitudinal aspect is evident in the overall description of the development of the focal supplier. More specific issues are covered in the separate studies, described in the appended articles.SME suppliers need basic capabilities of qualitative production performance as stepping-stones to develop more system supplier capabilities for added customer value. Development of stable production processes through lean implementation was by the focal supplier seen as a way to reach stable basic performance and to enable continuous development. The study further shows that knowledge integration with customers is an effective means to build system capability and indicates a stepwise and sequential process of developing specific supplier capabilities.The longitudinal case study deepens the knowledge of development of SME system suppliers and specifically point out three prerequisites that need to be in place for the supplier transition: (1) a capability of the supplier to manage internal processes of standardisation and continuous improvements for stable performance without disruptions, (2) a capability to collaborate in development projects with a limited number of customers, and (3) customer commitment to a long-term relationship. A customer demanding improvements is constantly driving its suppliers to better performance and proven supplier capabilities in turn promotes long-term customer commitment. The most essential component in supplier development is a competent and strategically oriented management, capable of identifying the specific system supplier offerings appropriate for the particular company in order to create customer value.This study contributes to better understanding of the conditions of medium-sized contract manufacturing SMEs, from a supplier perspective, and contributes to SCM research in illustrating how shifting responsibilities and subsequent activities in the supply chain may pave new competitive paths for SMEs. One issue here is the importance of knowledge integration for the development of supply chains. This has not often been discussed within SCM and thus provides a contribution to this theory.

Exploring design-driven innovation : A study on value creation by SMEs in the Swedish wood products industry
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Design-driven innovation, focused on the innovation of product meanings, provides a new perspective to better understand the contribution of design to innovation. Additionally, it enables new opportunities for value creation. At small and medium-sized enterprises (SMEs) in the Swedish wood products industry there is a need for such new value creation in order to remain competitive. However, design-driven innovation is not yet common in this context. Furthermore, there is little research on the innovation of product meanings focused on value creation. Therefore, the aim of this research is to explore value creation through design-driven innovation, in the context of SMEs in the Swedish wood products industry. This research addresses what value might be expected from design-driven innovation, as well as what enables and hinders this value creation. To address the aim, three studies have been conducted which are described in four appended papers. The studies consist of one systematic literature review and two case studies. The findings demonstrate that design-driven innovation contributes to value creation by focusing on product meanings, which intentionally addresses both tangible and intangible needs and therefore increases the perceived value of products. This research identified five facets of design-driven innovation which provide a structure to discuss what enables and hinders value creation. These are: (1) understanding new product meanings, (2) knowledge generation, (3) actors and collaborations, (4) capabilities, and (5) process. The facets can be seen as the origin of both enablers and barriers to value creation through design-driven innovation, depending on how they are addressed. Moreover, this research suggests that whether or not value is created is further influenced by the SMEs, their networks and the context in which they operate.

Developing decision-support tools for evaluation of manufacturing reshoring decisions
- 2020
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- During last three decades, companies have offshored their manufacturing activities across international borders in order to pursue lower manufacturing costs. Despite having accomplished their purpose, companies have also suffered from issues, especially poor quality of products and a poor response to customer demand. Therefore, companies consider relocating some of the manufacturing activities back to the home country, a process that is known as manufacturing reshoring. There is paucity of scholarly attention on how manufacturing reshoring decisions are evaluated and supported. Therefore, the purpose of this thesis is to develop decision-support tools to evaluate manufacturing reshoring decisions. In order to fulfil this, it is important to know how industry experts reason while making manufacturing reshoring decisions (RQ1), and how their reasoning can be modeled into decision-support tools (RQ2). Therefore, three studies were conducted including a multiple case study and two modeling studies. The multiple case study addressed the criteria that are considered by the industry experts in these decisions, while the two modeling studies, based on fuzzy logic and analytical hierarchy process (AHP), used a part of these criteria to develop decision-support tools. The findings indicate that a holistic set of criteria were considered by industry experts in arriving at a manufacturing reshoring decision. A large portion of these criteria occur within competitive priority category and among them, high importance is given to quality, while low importance to sustainability. Fuzzy logic modeling was used to model the criteria from the perspective of competitive priority at an overall level. Three fuzzy logic concepts were developed to capture industry experts’ reasoning and facilitate modeling of manufacturing reshoring decisions. Furthermore, two configurations and sixteen settings were developed, of which, the best ones were identified. AHP-based tools were used to capture experts’ reasoning of the competitive priority criteria by comparing the criteria. It was observed that fuzzy logic-based tools are able to better emulate industry experts’ reasoning of manufacturing reshoring. This research contributes to theory with a holistic framework of reshoring decision criteria, and to practice with decision-support tools for evaluation of manufacturing reshoring decisions.

Tidskriftsartikel (refereegranskat)abstract
- Research on competitive manufacturing (CM) in high-cost environments has earlier indicated that firms struggle to remain competitive and that manufacturing operations often have been offshored to low-cost environments. The purpose of this research is to explore and create a compounded view of challenges related to both internal and external environments of firms when operating in high-cost environments. This issue has been investigated through a qualitative case study involving five manufacturing firms in Sweden. This research has empirically derived the challenges associated with sustaining CM in high-cost environments and developed a prescriptive checklist. Seven main categories of challenges have been identified, ranging from a micro level related to product characteristics and employee involvement, to a macro level related to supply chain collaborations and industry systems. This research contributes to the existing literature on CM in high-cost locations by explaining and detailing what constitutes challenges in this kind of environment.
