In product modular design tasks, especially in the high-tech manufacturing industry, buyers and supplies play distinct roles, which may have different impacts on product architectural and modular innovation. Prior research has tended to view product innovation as a holistic concept, overlooking the importance of this differentiated influence. This study, from a modular design perspective, aims to clarify the impact of black-box supplier involvement on product architectural and modular innovation, as well as the influence of product modularity on these relationships.

Based on the theory of product modular design, this study decomposes product innovation into architectural and modular innovation from the perspective of the product internal structure to conduct in-depth theoretical analysis and model construction. A total of 276 valid questionnaires are collected from typical Chinese high-tech manufacturing firms and used to empirically test the constructed theoretical model using multiple hierarchical regression analysis.

The results show that black-box supplier involvement positively affects modular innovation and takes an inverted U-shape, as moderated by product modularity. However, the impact of black-box supplier involvement on architectural innovation shows contradictory differences at different modularity levels. Under a low level of product modular design, black-box supplier involvement has a negative impact on architectural innovation, but under a moderate level of modular design, it has a positive impact. After the degree of modular design exceeds a certain threshold, the impact gradually weakens.

The results provide valuable insights for managers, highlighting the need to avoid oversimplifying the innovation impact of black-box suppliers solely based on overall product innovation. Instead, a more accurate assessment of the innovation contributions of both the buyer and supplier should be based on the degree of architectural and modular innovation. Additionally, the findings suggest that managers should consider the alignment between their company's product modular design features and innovation priorities (i.e. modular innovation or architectural innovation) when determining an appropriate supplier collaborative development strategy.

This study not only reveals the different impacts of black-box supplier involvement on architectural and modular innovation, but also proves the significant synergistic innovation effect of the relationship between black-box supplier involvement and product modularization. It constitutes an enriched and deepened exploration in the existing research on supplier involvement in product innovation.

The purpose of this paper is to offer novel and complementary insights into the relationship between product modularity and product innovation by investigating the mediating role of module suppliers' relationship-specific investments which include both property-based relationship-specific investment (PRSI) and knowledge-based relationship-specific investment (KRSI).

This paper is an empirical study based on structural equation modelling, with a sample of 121 core firms of high-tech modular cooperation in China.

The findings indicated that product modularity had a significant positive effect on product innovation; product modularity was positively related to module suppliers' PRSI; module suppliers’ KRSI had a direct effect on product innovation while PRSI had an indirect effect on product innovation through KRSI; the relationship between product modularity and product innovation was serially multi-mediated by module suppliers’ PRSI and KRSI.

Modular product design and modular cooperation governance guidance for core firms and cooperative investment strategies guidance for module suppliers were provided.

This study is the first attempt to analyse how product modularity affects product innovation in the context of inter-firm modular cooperation by revealing the mediating role of module suppliers' relationship-specific investments.

The purpose of this paper is to propose a modular product design system and a product development roadmap (PDR), which can help to improve modular design (MD) and product innovation capabilities, respectively. Their relationships with product newness (PN) and new product performance are also assessed.

The proposed model was tested through structural equation modelling using data from a survey of 153 manufacturers in the electronic and electrical appliance industries in China.

The findings reveal that the proposed modular product design system and PDR can improve MD and product innovation capabilities. The authors also explore the conflicting relationships of MD and product innovation capability with PN.

The findings contribute to the literature by showing that MD can constrain PN while product innovation can improve it. The study provides new empirical evidence of these relationships and has strategic implications. In addition, this study identifies two product development techniques that can improve MD and innovation capability, respectively.

The authors provide new evidence of the relationship between MD and innovation capability at product level, and confirm a side effect of pursuing both in terms of new product development. Through empirical testing, the authors first verify two product development techniques for implementing modular product design and product innovation.

The purpose of this paper is to demonstrate modularity degree in terms of interfaces and innovation.

The research objective is achieved through a modeling approach for deciding modular architecture and its implementation regarding unique components and product innovation. A case example is presented to elaborate on the concept of modularity degree and provide an option for choosing the best module from different alternatives.

The presented approach can be considered a product design strategy, in which loose coupling is achieved through standardized component interfaces. Loosely coupled component interfacing is a prerequisite for developing mass customized products. There needs to be a decision support system to formulate the interfacing in order to achieve maximum benefits. This is illustrated in this paper.

The modeling strategy for measuring the modularity level is formulated theoretically. This approach needs to be validated through an empirical study in order to generalize its findings.

In the industrial arena there is a research gap in identifying and measuring the modularity level, which is formulated in the presented approach. It is hoped that this approach will contribute to filling this research gap in the business environment, which would further benefit managers of firms in their corresponding production processes.

The unique contribution of this modeling approach is articulated through analyzing product architecture, with a view to interpreting the component interfaces in a more productive way. This formulation triggers the decision‐making process in complex product development processes.

The purpose of this study is to establish an enhanced model of the innovation-decision process (IDP), specifically for construction. As context, innovation diffusion theory (IDT) is concerned with explaining how some innovations successfully stick whilst others fail to propagate. Because theoretical models provide abstracted representations of systems/phenomena, established IDT models can help decision-making units with innovation-related sense-marking and problem-solving. However, these occasionally fail or require enhancement to represent phenomena more successfully. This is apparent whenever middle-range theory seems ill-fitted to the complexity of construction.

Qualitative research via 13 semi-structured interviews occurred, with participants recruited via convenience and purposive sampling strategies. The study forms part of a broader mixed-method study (n = 246) informed by a research philosophy of pragmatism, investigating the applicability of classic IDT to the adoption of four-dimensional (4D) building information modelling (4D BIM) by the UK construction sector.

This diffusion study resulted in the adaptation of an existing IDP model, ensuring a better contextual fit. Classified more specifically as a modular-technological-process innovation, 4D BIM with its potential to provide construction planning improvements is used as a vehicle to show why, for construction, an existing model required theoretical extensions involving additional stages, decision-action points and outcomes.

This model can assist construction industry actors with future adoption/rejection decisions around modular-technological-process innovations. It also aids the understanding of scholars and researchers, through its various enhancements and by reinforcing the importance of existing diffusion concepts of compatibility and trialability, for these innovation types.

An enhanced model of the IDP, specifically for construction, is established. This construction-centric contribution to IDT will be of interest to construction scholars and to practitioners.

In the construction industry, building facade systems are gaining significance as reflected in the number of facade product innovations available on the market. While research studies on the adoption of these facade product innovations are comparatively limited in number. An awareness of the advantages and impacts that a product innovation brings is critical in its adoption, and therefore the purpose of this paper is to develop a classification framework for the use of producers/vendors present the advantages and impacts of their innovative facade products to the architects.

The study, in addition to literature review, consisted of four main steps without distinct boundaries, namely, (1) case study sample selection regarding facade products, (2) data collection through review of published documents, analysis of the data via content analysis and generation of a preliminary framework for the evaluation of facade product innovations, (3) further data collection through semi-structured interviews and analysis of the products and (4) redefining innovation types and finalizing classification framework through assessment of new facade products.

Innovation types may vary according to the product groups under investigation and viewpoints of the classifications. Selected facade products were evaluated in terms of their specific characteristics through identified viewpoints: as a physical object and as an agent. It was revealed that assessing a product innovation in terms of changes in its structural composition and impact on other related physical objects/processes can change the type of innovation. Additionally, insights about improved characteristics specific to facade products, forms of change in these products and architects' new actions in the facade design process were obtained.

Only the products stated by the producers/vendors as being new to the Turkish market at the time they were introduced were evaluated in terms of all aspects proposed in the framework. For these products and others that were evaluated, the product data obtained from the producers/vendors have been deemed to be accurate. Research on equivalent products in the market has not been conducted.

Studies identifying innovation types in the facade industry are very rare. The proposed framework can be regarded as a detailed investigation of product innovation types in the facade industry which offers component-system level improvement/change analysis. Moreover, it can be an effective tool for producers/vendors to ensure that architects have knowledge about their innovative products and their impacts on facade design and also to facilitate the adoption of these products.

This paper aims to explore the role of customer engagement during the production of services in a modular innovation. Modularity can be used to explain the structure and relationship in services innovation.

The authors explore the theory of modularity focussing on the context of consumer engagements. They adopted ideas from product modularity and approach services using modular principle.

Contrary to the extant literature, the authors are content that the transactions between the participants were mainly conducted at thick crossing points. By focusing on thin crossing point, the service provider will achieve better overall service structure.

There is a need to focus on specifying interface to define how service modules and service providers interact with the customer within the service.

By engaging customer, modular principle can help firms achieve cost efficiency, higher product and process variety, as well as better response to individual customer needs.

This paper scrutinises the engagement of customer and conceptualises the role of customer in modular innovations that have been previously neglected.

The purpose of this paper is to describe different ways in which a buyer and supplier can be embedded in a dyadic relationship and how these differences influence patterns of inter-firm innovation activities and outcomes. Specifically, to address the relative paucity of theoretical work on how dyadic configurations influence parties’ joint innovation behavior, this study examines how different buyer-supplier embeddedness (BSE) configurations change the four choices that pertain to the levels of involvement buyers and suppliers exhibit in inter-firm innovation activities. These choices concern the processes buyers use to engage suppliers; the scope of efforts in each party; the locus of effects determining the beneficiaries; and the extent to which parties disclose private innovations within the relationship.

Drawing on social embeddedness literature, the authors conceptualize dyad level, BSE in two dimensions: relational and structural. The relational dimension describes the quality of relationship, while the structural dimension describes the intensity of exchanges between the parties. Together these dimensions allow the authors to map the differences in BSE configurations and provide a basis for exploring their links to inter-firm innovation patterns.

The authors demonstrate the configurational approach to the innovation patterns in inter-organizational setting. That is, the authors conclude that different configurations of BSE are likely to produce distinctive patterns of choices for inter-firm innovation activities.

This study applies social embeddedness perspective to conceptualize dyadic BSE. Adoption of this concept allows dimensionalizing the dyadic relationships into two distinct dyadic elements, relational, and structural dimensions. Also, the concept has rich implications for how partner firms interact and share information. The dyad’s innovation potential and patterns are considered based on the configurations of dyadic embeddedness.

The purpose of this paper is to explicate why and how modularization of business models can lead to path dependence or strategic flexibility, thus either inhibiting or favoring business model innovation.

Conceptual paper that depicts a model based on the extant literature. The derived implications for business model innovation are illustrated by several examples.

Modularity can be used as cognitive frame to explore issues of dynamics, evolution and transformation of business models. Thereby, the paper reveals drivers as well as barriers to business model innovation which sensitizes managers that modularity as a design principle is a two-edged sword: managers cannot simply rely on what they know about the benefits of modularity because this might lead to path dependence in the future.

The authors suggest that middle managers might best focus on managing modules and their direct relations. Senior management should put more emphasis on encouraging extra-modular thinking.

By outlining the concept of business model modularity, the authors add to the scarce literature that addresses modularity beyond the fields of products, production and organization design. The discussion also advances to the literature on drivers as well as barriers to managing business model innovation. While most of the extant literature has portrayed modularity as a means to increase flexibility, only a few studies have revealed the downside of modularity and explained how it gives rise to path dependence. In this respect, the authors highlight the relation between managerial action, self-reinforcing mechanisms and characteristics of the environment. Finally, the paper’s findings provide a lens to consider contradictory strategies simultaneously which is crucial for managing complex business models.

The automotive industry has been studied extensively, but few studies focus on outbound logistics in automotive supply chains, or on the logistics service provider’s (LSP’s) point of view. Furthermore, there is hardly any research on service model innovation in LSPs. The purpose of this paper is to narrow these research gaps.

The analysis is based on a single-case study – an LSP that specializes in services for the automotive industry. The paper examines the company’s service models and their development over time.

The findings show how the case company has moved towards multifaceted service models through a number of radical and incremental innovations. Moreover, it has used the same methods in developing all its new service models, and has applied modularity principles in service innovation to achieve better process efficiency and service effectiveness.

The rather narrow focus of this study – automotive logistics in a specific area – decreases the generalizability of the findings beyond this context. However, the single-case approach offers in-depth insights, and the analytical frameworks developed herein for service models is applicable in other contexts.

The analysis may help LSPs and service companies in their service design and development. The use of modularity principles makes it easier to offer mass-customized services and to develop efficient processes.

This study narrows a research gap in examining outbound logistics services in the automotive supply chain and focussing on the LSP’s perspective.
