Abstract
Purpose
The purpose of this paper is to explore how integral and modular product architectures influence the design properties of the global operations network.
Design/methodology/approach
The authors perform a multiple-case study of three global manufacturing companies, using interviews, seminars and structured questionnaires to identify ideal design properties.
Findings
The authors find that the choice of integral vs modular product architecture lead to significant differences in the preferred design properties of global operations networks concerning number of key technologies in-house, number of capable plants, focus at assembly plants, distance between assembly plant and market, and number of key supplier sites. Two of these were identified through this research, i.e. the number of capable plants and number of key supplier sites. The authors make a distinction between component and assembly plants, which adds detail to the understanding of the impact of product architecture on global operations. In addition, they develop five propositions that can be tested in further survey research.
Research limitations/implications
This study is restricted to three large manufacturing companies with global operations. However, the authors investigated both integral and modular products at these three companies and their associated global operations network. Still, further case or survey research involving a broader set of companies is warranted.
Practical implications
The key aspects for integral products are to have many key technologies in-house, concentration of production at a few capable plants, and economies-of-scale at assembly plants, while long distances between assembly plants and markets as well as few key supplier sites are acceptable. For modular products, the key aspects are many capable plants, economies-of-scope at assembly plants, short distance between assembly plants and markets, and many key supplier sites, while key technologies do not necessarily have to reside in-house – these can be accessed via key suppliers.
Originality/value
This paper is, to the authors’ knowledge, the first study on the explicit impact of product architecture on global operations networks, especially considering the internal manufacturing network.

Abstract
Purpose
The purpose of this paper is to explore how global operations of manufacturing companies influence the choice of product architecture decisions, ranging from integral to modular product designs.
Design/methodology/approach
The authors perform a multiple-case study of three global manufacturing companies with integral and modular product architectures.
Findings
The authors find that the internal network capabilities, the number of capable plants, the focus of component plants, the focus of assembly plants, the distances from key suppliers to internal plants, and the number of market segments significantly influence the choice of integral vs modular architecture.
Research limitations/implications
This study is limited to three large manufacturing companies with global operations. However, the authors investigate both integral and modular products. The authors develop propositions that can be tested in further survey research.
Practical implications
The findings show that the type of global operations network influences the decision on product architecture, such that certain global operations characteristics support integral product designs, while other characteristics support modular designs.
Originality/value
To the best of the authors’ knowledge this paper is the first study on the explicit impact of global operations on product architecture, rather than the other way around.

Abstract
Purpose
The purpose of this paper is to present recent empirical results concerning offshoring and backshoring of manufacturing from and to Sweden, to increase the understanding of manufacturing relocation in an international context. In particular, extent, geographies, type of production, drivers, and benefits of moving manufacturing in both directions are investigated.
Design/methodology/approach
The study is based on survey data from 373 manufacturing plants. The same set of questions is used for both offshoring and backshoring between 2010 and 2015, which allows similarities and differences in decision-making and results between the two relocation directions to be identified.
Findings
There are many significant differences between offshoring and backshoring projects. Labour cost is the dominating factor in offshoring, as driver and benefit, while backshoring is related to many drivers and benefits, such as quality, lead-time, flexibility, access to skills and knowledge, access to technology, and proximity to R&D. This is also reflected in the type of production that is relocated; labour-intensive production is offshored and complex production is backshored.
Research limitations/implications
Plants that have both offshored and backshored think and act differently than plants that have only offshored or backshored, which is why it is important to distinguish between these plant types in the context of manufacturing relocations.
Practical implications
The experience of Swedish manufacturing plants reported here can be used as a point of reference for internal manufacturing operations.
Originality/value
The survey design allows a unique comparison between offshoring and backshoring activity. Since Swedish firms in general have been quite active in rearranging their manufacturing footprint and have experience from movements in both directions, it is an appropriate geographical area to study in this context.

Abstract
Purpose
Supply chains evolve and change in size, shape and configuration, and in how they are coordinated, controlled and managed. Some supply chains are mature and relatively unchanging. Some are subject to significant change. New supply chains may emerge and evolve for a variety of reasons. The purpose of this paper is to examine the nature of supply chain evolution and address the question “What makes a supply chain like it is?”
Design/methodology/approach
The paper analyses and develops key aspects, concepts and principal themes concerning the emergence and evolution of supply chains over their lifecycle.
Findings
The paper defines the supply chain lifecycle and identifies six factors that interact and may affect a supply chain over its lifecycle – technology and innovation, economics, markets and competition, policy and regulation, procurement and sourcing, supply chain strategies and re-engineering. A number of emergent themes and propositions on factors affecting a supply chain’s characteristics over its lifecycle are presented. The paper argues that a new science is needed to investigate and understand the supply chain lifecycle.
Practical implications
Supply chains are critical for the world economy and essential for modern life. Understanding the supply chain lifecycle and how supply chains evolve provides new perspectives for contemporary supply chain design and management.
Originality/value
The paper presents detailed analysis, critique and reflections from leading researchers on emerging, evolving and mature supply chains.

Abstract
We use the methodology from quality function deployment (QFD) for linking manufacturing flexibility to market requirements. This approach creates a framework for modelling the deployment of the need for flexibility from the customers’ viewpoints into manufacturing flexibility at various hierarchical levels. We present an application of the methodology in a real case study at a firm where a manufacturing system was being redesigned for the manufacture of a new and wider range of products than previously, based on a new product platform. Based on the case study we discuss the benefits and limitations of using the QFD approach to deploy manufacturing flexibility. The paper also presents a literature review of the manufacturing flexibility framework arena.

Abstract
Purpose
The purpose of this paper is to systematically review the extant literature on the relationship between product architectures and supply chain design to identify gaps in the literature and identify future research opportunities.
Design/methodology/approach
This paper examines the peer-reviewed literature on product architectures and supply chain written in English. The search strategy is based on selected databases and keywords. In total, 56 articles from 1995 to 2013 were identified.
Findings
Three key dimensions are identified for the categorization of the literature: the type of product architecture, the type of supply chain and the research methodology. Furthermore, we identify themes related to outsourcing, supplier selection, supplier relationships, distance from focal firm and alignment.
Research limitations/implications
The present search strategy may have missed some references that are related to the area. However, as a counter-measure, we used back-tracking and forward-tracking to identify additional relevant papers. A research agenda is proposed for further research on the interaction of product architectures and supply chain design.
Originality/value
This paper is, to the best of the authors’ knowledge, the first broad review that investigates the interrelationship between product architectures and supply chain design.

Abstract
Purpose
The purpose of this paper is to present and test a new model for competitive capabilities. Traditionally, a cumulative model has been viewed as having one sequence of building competitive capabilities in a firm in support of market needs, including quality, delivery, cost efficiency and flexibility. Although appealing as a conceptual model, empirical testing has not been able to fully support the cumulative model. This paper acknowledges the need for a hybrid approach to managing capability progression. It brings together the literature on trade‐offs, cumulative capabilities, and order winners and qualifiers.
Design/methodology/approach
A new hybrid approach for modelling competitive capabilities is tested empirically using data from the high performance manufacturing (HPM) study, round 3, including three industries and seven countries – a total of 211 plants.
Findings
The hybrid model shows significantly better fit with the data from the sample than the cumulative models suggested by previous literature. Empirical support is found for the traditional perception that a high level of quality is a prerequisite for a high level of delivery performance. However, cost efficiency and flexibility do not exhibit a cumulative pattern. Instead, the results show that they are developed in parallel. The findings suggest that a balance between cost efficiency and flexibility is built upon high levels of quality and delivery performance.
Research limitations/implications
Since we limit the empirical investigation to three industries and seven countries, it would be interesting to extend the testing of this model to more industries and countries. This research shows that combining perspectives and insights from different research streams – in this case, trade‐off theory and the concepts of cumulative capabilities, and order winners and qualifiers – can be fruitful.
Practical implications
The results of this paper provides managers with guidelines concerning the configuration of competitive capabilities. First, a qualifying level of quality needs to be attained, followed by a qualifying level of delivery. Then, a balance between potential order winners, i.e. cost efficiency and flexibility, needs to be attained.
Originality/value
This paper presents a new approach to modelling competitive capabilities that synthesises previous research streams and perspectives from cumulative capabilities, contesting capabilities (trade‐offs), and order winners and qualifiers.

Abstract
Whilst much of the e‐business evolution has been referred to as an additional and complementary marketing channel, there has been little concern about the impact on manufacturing. However, since a manufacturing strategy should be closely linked to the marketing strategy, developments in marketing are likely to impact manufacturing. In this paper, we explore the ways in which e‐business is impacting the manufacturing strategy in manufacturing firms. We study seven Swedish manufacturing firms and investigate the relationship between e‐business and manufacturing strategy. The findings indicate that e‐business mainly affects two decision categories – vertical integration, and manufacturing planning and control systems – through new ways to communicate and exchange information between buyers and sellers at both business ends. Improvements in these decision categories lead to potential gains in delivery speed and reliability, but only for make‐to‐order companies, whereas the impact on quality, price and flexibility is more or less negligible. Make‐to‐stock firms report only limited impact on manufacturing.

Abstract
Purpose
The purpose of this paper is to shortly overview the research in international operations management (OM), to provide background to the papers published in this special section.
Design/methodology/approach
As a literature review, the paper investigates the past, present, and future of international OM. It is not a systematic review; the paper just highlights the most important international operational management research networks, streams and concepts in the field.
Findings
The paper finds that there is a time lag in the field of international OM compared to other research areas within international business and management. It provides some ideas for the future to be researched.
Originality/value
The paper gives a focused review on international research networks which has not been done before. It also identifies two different streams of researches in international OM: the stream investigating OM differences among geographical areas, and the stream dealing with issues of international manufacturing networks.

Abstract
Purpose
The paper seeks to test the relationships among product design and supply chain design, with specific reference to the product‐supply chain model by Fisher.
Design/methodology/approach
An extensive empirical survey with data from 128 companies; the approach is basically theory testing, in that it investigates an existing framework, and discusses extensions.
Findings
Significant relationships are found between product types and supply chain types, as well as concerning the impact of alignment on performance.
Research limitations/implications
Instead of treating the supply chain characteristics associated with different supply chain types as either/or choices, some companies select properties from both supply chain types in order to gain additional benefits. This creates a supply chain frontier of physical efficiency and market responsiveness; a concept that deserves further attention by researchers. A limitation is that it would be interesting to perform a longitudinal study.
Practical implications
Different product types call for different types of supply chains. Alignment between the type of product and the type of supply chain is important, and significant for delivery speed, delivery dependability, and cost performance.
Originality/value
This research empirically tests a model that has received considerable attention in the research literature as well as acting as guidelines in practice, but that has not been tested explicitly before.
