## Abstract

Under the technological innovation network, loosely coupled organizations featured by weak connections and relative independence have formed through the dynamic division of labor and knowledge sharing of enterprises. The loosely coupled organizations greatly enhance cooperation performance, but face problems such as poor flexible matching between partners and low innovation efficiency. Meanwhile, modular organizations can connect with other organizations to realize a specific operational goal via contracts and carry prominent features such as collaborative innovation, adaptive division of labor, and dynamic capabilities, offering an effective network governance model for collaboration between enterprises. Based on the two dimensions (looseness and coupling) between organizations, this paper uses the design dependency matrix (DDM) to map demands for functional/design modules, under the division of labor within products and the decisions on product modules, and preliminarily decouple the functional/design modules. Based on clustering DDM, a decision structure matrix (DSM) was constructed, and the clustering decoupling algorithm was adopted to create clustering design structure modules. Referring to these clustering modules, intraproduct division of labor was performed to realize the modular cooperation between organizations.

## 1. Introduction

The era of information economy has two defining trends: the growing complexity of product systems and the increasing complementarity between production knowledge. The ensuing division of labor within products has deepened the economic globalization [1]. The sudden change in technology, coupled with the individualization of user needs and the complexity of products, requires enterprises to establish new organizations that better adapt to the environment, reorganize resources more quickly, and realize integration and coordination of global resources. The paradigm of corporate innovation is shifting from independent innovation of individuals to the economy of the local area and the decentralized innovation network. During the paradigm shift, enterprises continue to integrate value chain resources through platformization and strengthen their expertise and participate in the division of labor in the value chain through modularization [2]. Each platform integrates the subsystems in the form of modules through standard interfaces, making the platform stable, tasks diverse, and response agile [3, 4].The homogeneous competition strategy, which is common in the industrial economy era, has been replaced by the heterogeneous cooperation strategy based on the complementarity of production knowledge [5]. Meanwhile, comprehensive hierarchical organizations have been gradually overtaken by interconnected and modular nonhierarchical entities. According to the division of labor, enterprises combine cooperation contracts dynamically into a flexible contract network. The modular nodes in the network can perform adaptive division of labor and collaborative innovation. This simplifies the control of complex systems [6], enhances the innovation of product development, and shortens the time for the products to hit the market. The modular network organization is generally characterized by low density and high centrality [7]. On the one hand, the organizations are loosely coupled to realize the collaboration of organizational elements and achieve cooperative innovation. On the other hand, the member modules are required to maintain a high independence.Modular organizations have become the essence of the new organization model and industrial structure in the environment of business innovation [8, 9], offering a highly competitive organization model. By the loose coupling between task modules, enterprises efficiently allocate resources, implement fast transactions, and fully tap the potential of internal and external resources, thereby coping with complex tasks [10]. As a new value creation system, modularization allocates resources on the value chain with modules as nodes, creates values for enterprises and consumers with its own capabilities, and points out the direction for business practices in the era of tremendous changes. Based on the modularization principle, the platform organizations are an organizational form that can dynamically allocate resources to satisfy personalized needs and support entrepreneurship. It is an ideal organizational form for enterprises to face future challenges. In business practice, enterprises such as Toyota and Haier have made breakthroughs in product development through the innovation of modular organizational structure.From the modularization of product technology to the modularization of enterprises and industrial organizations and then to the construction of modularization network organization of industrial value chain, the evolution and extension of modularization theory follow the same line. Modularity not only greatly changes our real life but also opens up new fields for theoretical research. However, how to optimize organizational structure to make better use of their own development and external environment is a prominent problem faced by modern enterprises. The existing theoretical basis is not enough to achieve multidegree of freedom and adaptive rapid changes to module instances. And, with the increasing complexity of products, there are still many theoretical and practical application problems to be further explored. Few scholars have specifically studied the rules that encourage the participation of modular members and their mutual relations [11].During innovation and cooperation, organizations are troubled by the poor flexible matching between partners and the low innovation efficiency. The main cause of these troubles is that the organizations, through cooperation and innovation, form loosely coupled organizations in the form of a dense or sparse network; there have not been modular organizations that are tightly correlated and loosely coupled. To solve the problem, this paper takes the loose coupling between organizations as the entry point and follows the evolution path of modularization “technology modularization ⟶ product modularization ⟶ organizational modularization.” Focusing on loosely coupled organizations, the authors tried to develop innovative reform strategies for organizations to remove coupling and enhance modularization. The research results enhance the enterprises’ ability to adapt to dynamic complex environment and to integrate resources, increase the consumer responsiveness, and enrich the theories on modular organizations.


## 2. Literature Review

Modularization as a concept can be tracked back to Simon’s nearly decomposable system. Simon defined the nearly decomposable system as a hierarchical system, in which the subsystems have weak interactions, and the internal elements in each subsystem have strong interactions [12]. Simon held that a hierarchical decomposable system helps to compress information and eliminate complexity by enhancing intramodule connections and weakening intermodule connections [12]. In recent years, Simon’s nearly decomposable system has been renamed as modularity hypothesis [13] and gradually penetrated multiple disciplines. The research of modularity mainly focuses on three aspects: product design modularity, production system modularity, and organization design modularity.In terms of product modular design, Baldwin and Clark were early proponents of modularization, suggesting that the industry has currently entered a boom of modular design, production, and consumption [14]. Under the premise of preserving system integrity, a complex system can be simplified by decomposing it into several decoupled or weakly coupled modules (similar to completely deconstructed or semiautonomous subsystems) along the coupling points and linking up the modules by certain rules. This idea of “near deconstruction” was later developed into a concept at the level of product design and applied as a new method of developing and producing complex products [15]. The research of product modular design mainly includes product module planning, modular product configuration, and module evolution. In the aspect of product module planning research, technology modularization is the prerequisite for product modularization [16], Erixon et al. [17] proposed 11 conditions to map functions into modules, establish subfunction association matrix, and cluster subfunctions to form modules. With the increasingly fierce market competition, customer demand plays an increasingly important role in the design stage, prompting more and more scholars to pay attention to the role of customer demand in module division. Ericsson and Erixon [18] used the House of Quality to analyze customer requirements and established the relationship between customer requirements and product components. Tseng et al. [19] used the analytic hierarchy process (AHP) to evaluate customer needs and determined whether the customer needs were met according to the evaluation results. Module planning is the foundation of the implementation of modular technology.In modular product configuration research, the purpose of product configuration is to obtain the product solution or solution set that meets the requirements in a reasonable time. Ostrosi et al. [20] established a fuzzy model considering various factors related to product configuration and used fuzzy operations to solve product configuration problems. Zhaoxun and Liya [21] used neural network to study the interactive learning of configuration knowledge in the configuration process to optimize the product configuration process. At present, many achievements have been made in product configuration, but the research on the extensibility of the configuration model is still in its infancy.In the aspect of module evolution research, most of the current research studies take product family as the object. Wheelwright and Sasser [22] established a product development map to describe the evolution of enterprise product lines based on the actual needs of enterprise product development strategy management. Meyer and Utterback [23] took product family as the object and established product family map to describe the evolution pattern of product family, so as to establish enterprise management plan, expand new markets, realize product update, and promote the long-term development of enterprises. It is a new strategic research field that combines modularity theory with network theory, platform strategy, and supply chain management theory. Modular supply chain is a kind of modular network organization, and its basic component unit is the supply chain module. There are certain either parallel or prior constraints between these modules. Vendors are divided into modules based on the functionality of the product and the type of resources required, and they either cooperate or compete to deliver the modules effectively. The “final assembly plant” of the enterprise plays the role of interface rule designer in the integration operation of these modules. It is responsible for establishing the structure and interface between modules and ensuring that the interaction and coupling between modules meet the preformulated standards so that the whole supply chain forms a modular network structure. At the same time, Sanchez [24] regards modularity as a platform strategy to create flexibility, which makes it easier to set up a portfolio of current and future product options, thus enabling faster innovation and tighter cost control.In the aspect of production system modularization and organization design modularization, it discussed the relationship between product module and organization module and the design method of organization module. The theory of modularity that guides organizational design originates from the view that product architecture determines organizational architecture proposed by Sanchez and Mahoney [25]. Sanchez and Mahoney [25] hypothesized that modularity in the product design would lead to modularity in the organizational design. This view supports many studies on the advantages of modularity, which show that modularity in the product design has become an important strategy for realizing modularity in the organizational design. However, there are different conclusions about modular technology and modular organization and their relationship. Benassi’s [26] research shows that the modular organization itself is a kind of innovation, not just the structure of modular products. In this context, modularity is used primarily by analogy. Products can be broken down, just as the organization of a company can be broken down. The modularity of the product enables compatibility and extensibility. While product modularity reduces complexity and enables uniformity and standardization, organizational modularity is designed to explore new solutions that make it less important to break down the organization and get each unit to do its job in the same way.In the aspect of organization design modularization, a new direction has emerged in the field of strategy and technology innovation, the correspondence and matching relationship between technology and organization. A representative theory in this direction is the “mirror image” hypothesis, which is closely related to the product design [27, 28]. Building a modular organization, standard component interfaces or design rules are thought to reduce the need for business coordination or communication [25, 29]. Baldwin and Clark [3] advocated the modular systems that coordinate or handle the relations between modules with clear and standardized interface rules. From the perspective of module combination, however, not every module can make an automatic response, while coupling or cooperating with other modules. Human response is often necessary depending on the specific situation [30, 31]. When the intermodule interface rules become clear visible information without the prior design, the actors of each module have a great initiative to coordinate the relationship between the modules.The above analysis shows that although there are controversies in the relationship between product modularity and organization modularity, the mainstream research is inclined to study the corresponding and matching relationship between technology and organization, as well as the “mirror” hypothesis which is closely related to the product design. Therefore, the designers of such organizations should highlight the interface rules between organizations. Nevertheless, there are no pertinent methods to handle the two dimensions (looseness and coupling) between organizations, overcome the lack of innovation efficiency induced by too many modular organizations, and create modular organizations with tight correlations and loose coupling. Therefore, this paper analyzes the relationship between the two dimensions between organizations and modular organizations and introduces design rules to decouple the relations between loosely coupled organizations, turning them into modular organizations that are tightly correlated and loosely coupled.


## 3. Relationship between Loosely Coupled Organizations and Modular Organizations

The current research of coupling mainly focuses on two cases: the coupling based on resource integration, i.e., the coupling between organizations through the division or exchange of the values of information and resources through workflow division; the coupling based on informal social exchanges, i.e., the coupling between organizations through the trust and noncontractual relationship formed via long-term cooperation.The above two loosely coupled organizations exist widely between innovation network subjects, due to the openness and diversity of innovative subjects and resources and the dynamicity of collaborative tasks. Under the two cases, the coupling elements and forms between different subjects directly affect the reliability and efficiency of the cooperation system. For the coupling based on resource integration, the cooperative stability and innovation efficiency are affected by cooperation contracts; the innovation efficiency will be suppressed by too many contracts. For the coupling based on informal social exchanges, the stability is relatively high, but the innovation efficiency will decrease with the growing ties between organizations.Concerning Simon’s nearly decomposable system, the scholars often treat coupling as the basic concept of the research into organizational modularization. Sanchez and Mahoney [32] explained loose coupling as a 1D process: the development from loose coupling to close coupling. Orton and Weick [15] classified the loose coupling between organizations into two dimensions: the uniqueness of each component and the responsiveness between components. The uniqueness determines the degree of coupling between organizations, while the responsiveness determines the closeness between them. Depending on the presence/absence of the two attributes, the degree of loose coupling between organizations can be divided into close coupling, loose coupling, decoupling, and no coupling (Table 1). If both attributes coexist, the organizations form a loosely coupled system. Whether in 1D classification or 2D three-degree classification, loosely coupled organizations do not correspond to modular organizations [33].Table 1
2D three-degree classification of organization coupling.
2D two-degree classificationUniquenessNoYesResponsivenessNoUncoupled organizationsDecoupled organizationsYesClosely coupled organizationsLoosely coupled organizationsData source is compiled from the opinions of Weick [15].Wang and Zhang [33] redefined the 2D classification and divided organizations into six types (abbreviated as 2D three-degree coupling), depending on the presence/absence of uniqueness and responsiveness (manual response, automatic response, and no response) (Table 2).Table 2
2D three-degree classification of organization coupling.

Wang and Zhang [33] stated that, in the 2D three-degree classification, the loosely decoupled organizations are modular organizations. If some design rules are introduced, the loosely coupled organizations will be transformed into loosely decoupled organizations, i.e., modular organizations, and this design will meet the requirement on automatic response. Modular systems do not eliminate the coupling state, yet differ from integrated systems. A modular system is a loosely coupled system that embodies the dialectical unity of module independence and network integrity [25]. Modular deconstruction is to make inter-subsystem connections weaker than intra-subsystem connections, thus forming a loosely coupled system with multiple modules. After modular deconstruction, designers need to integrate related modules into a whole system by explicit and/or implicit rules and realize the so-called “modular assembly” [14].The interorganizational relationship is explained in Figure1. In Figures 1(a) and 1(b), a, b, and c are three design parameters of the system; X means the parameter is adjustable; ● means the relationship is fixed. It can be seen from Figure 1(a) that “a” alone forms a module, while b and c constitute a module; there is an adjustable dependence between module a and module b-c (there is a parametric dependence between a and c); therefore, the two modules are loosely coupled.Figure 1
Transformation of interorganizational relationship.
(a)(b)If a ruleG is configured during the system design, then each module of the system must be designed following that rule. The preset rule G can eliminate the dependence between a and b-c. Depending on the property of G, the system could belong to one of two types. If rule G is an industrial standard for new products (manual response), then Figure 1(b) is loosely coupled organizations. If rule G is a design rule, then Figure 1(b) is loosely decoupled organizations. In the latter case, the original dependence between modules is gone. The coupling between modules is embedded into the designed rule so that the organizations acquire the attributes of uniqueness and automatic responsiveness. These are the strength of modular organizations.


## 4. Decoupling and Modular Design under Product Modularization

According to the corresponding and matching relationship between technology and organization, as well as the “mirror” hypothesis, organizational modularization reflects the contents of intraproduct division of labor, which mainly depends on technology. Therefore, the design dependency matrix (DDM) was adopted to modularize products, and the decision structure matrix (DSM) was employed to transfer the technology modularization under product modularization. Based on technology modularization, the intraproduct division of labor was organized, i.e., the organizations were modularized.


### 4.1. Mapping and Cluster Analysis of Demands to Functional/Design Modules

The DDM is a matrix analysis tool for discussing the constrained correlations between product functional demands and technical designs [35]. The DSM is a matrix that facilitates the analysis of the dependence between technical design modules [36]. To increase the internal coupling and reduce the external coupling of organizational modules, the functional modules must be loosely coupled with design modules. Hence, the DDM was adopted to map consumer and design demands to product modules and perform cluster analysis. The DDM can be defined as follows.The DDM is anm×n matrix, where the ith row (ri, i∈m) is the demand of the ith consumer, and the jth column (lj, j∈n) is the jth functional/design module (∃i∈mandj∈ni). If ri∩lj≠∅, the element of the DDM dij=1; otherwise, dij=0. This process is repeated to establish the DDM correlation matrix D=dij, where i=1,2,…,mandj=1,2,…,n.The cluster analysis was performed on the established correlation analysis. The demands and modules were clustered into several classes. The DDM clustering algorithm is detailed in [32, 35] with the minimum degree of coupling.Take product P for example. Figure2(a) shows the mapping from its consumer demands 1–6 to the functional/design modules a-h of products. The irrelevant columns were removed through cluster analysis, producing the demand modules A and B (Figure 2(b)). In each class, the modules were irrelevant with the consumer demands corresponding to the modules in other classes; the coupling between classes was thus minimized.Figure 2

### 4.2. DSM Prototype Mapping and Module Decoupling Analysis

Functional modules and design modules need to cooperate according to the intraproduct division of labor. To enhance the cooperation flexibility, it is necessary to reduce the coupling between the modules, i.e., implement decoupling. The DSM describes the relationship between modules. The rows and columns are both the module columns in the DDM correlation matrix. Here, irrelevant modules are added to the last row and last column of the DSM simultaneously [37]. The relationship between functional/design modules was divided into strong correlation and weak correlation. The corresponding matrix elements are denoted as X and ▬, respectively. Based on the results of DDM clustering, the DSM mapping was determined in light of the weak/strong correlations between functional/design modules. The mapping process is illustrated in Figure 3, with product P as an example.Figure 3
DSM prototype mapping to DDM.The DSM prototype in Figure3 shows the strong correlation between module and external design module h, that is, module B is coupled with module h. To reduce the degree of coupling, the DSM should be further clustered and decoupled. In the clustered DDM, the modules in each class are irrelevant to the consumer demands corresponding to other classes, i.e., the coupling is minimized between classes. Therefore, the DSM phase stresses on the coupling between clustered modules and original design modules (e.g., modules g and h). The decoupling was realized into the following steps:Step 1. Import the DSM prototype D0Step 2. Traverse the strongly correlated elements dij in D0Step 3. If ∃dij=X∩Mi≠∅, incorporate module j into Mi⟶MijStep 4. Iteratively implement Steps 2–3 until ∄dij=X or dij=X∩Mi=∅Step 5. Diagonalize Mij to move all the nonempty elements dij in Mij close to the diagonalStep 6. Rank the modules by the height of the column containing weakly correlated elementsStep 7. Merge the modules into different modularization plansTaking productP, for example, a DSM prototype (D0) was constructed according to the clustering DDM of the product (Figure 4). Then, the prototype (D0) was traversed. Since ∃ddh=X∩Mdeb≠∅, h should be incorporated into Mdeb (matrix D1 in Figure 4). After that, the new module Mdebh was diagonalized to obtain matrix D2 in Figure 4. Furthermore, the modules were ranked by the height of weakly correlated elements, producing matrix D3 (Figure 4), i.e., the decoupled module prototype.Figure 4
Decoupling process.Through the above decoupling process, the strongly correlated modules were combined into one clustered module, and the modules containing weakly correlated elements of the same height were allocated into another clustered module, thereby reducing the coupling between modules.

To enhance the cooperation flexibility, it is necessary to reduce the coupling between the modules, i.e., implement decoupling. The DSM describes the relationship between modules. The rows and columns are both the module columns in the DDM correlation matrix. Here, irrelevant modules are added to the last row and last column of the DSM simultaneously [37]. The relationship between functional/design modules was divided into strong correlation and weak correlation. The corresponding matrix elements are denoted as X and ▬, respectively.

The mapping process is illustrated in Figure 3, with product P as an example.Figure 3

## 5. Modularization Plan and Judgement Based on DSM Prototype

Through decoupling, a complex product can be split into several modules, providing a guide for intraproduct division of labor. The modularization-based intraproduct division of labor realizes the docking between modules and makes the modules more flexible. However, the modules in the DSM prototype might sometimes be too refined. Before guiding intraproduct division of labor with the prototype, the prototype modules should be recognized based on the evenness of modules, as well as inter- and intramodule coupling. Then, the modularized division of labor can better promote design and production.After DSM clustering, product P was divided into two strongly correlated modules (M1 and M3) and one weakly correlated module (M2) (Figure 5).Figure 5
DSM prototype.Based on the prototype, the modulesM1, M2, and M3 were combined according to actual demands, forming new modularization plans. In Figure 6, plan 1 is the DSM prototype, plan 2 merges M1 with M2, and plan 3 merges M2 with M3.Figure 6
Modularization plans based on DSM prototype.Depending on the actual demands, the modularization plans can be selected in consideration of the evenness of modules, as well as inter- and intramodule coupling.For productP, the weakly correlated module M2 in DSM prototype could be combined with M1 or M3. If M2 is combined with M1, plan 2 will be obtained; if M2 is combined with M3, plan 3 will be obtained. In plan 2, the two modules have four submodules each. The evenness of plan 2 is better than that of plan 3. The two modules in plan 2 are weakly coupled due to the presence of factor e. The two modules in plan 3 are weakly coupled due to the presence of factor g. Hence, element g can be extracted as the preset rule, which is the requirement of design modules (a nonmanual response element), to decouple the two modules.


## 6. Conclusions

Organizational modularization design is a double-edged sword. On the one hand, modular organizations can adapt to the environment of technical cooperation and division of labor, enhancing the organizational flexibility; on the other hand, if there are too many modular contracts in an uncertain environment, the organizational innovation will be impeded, making it hard for the organizations to output innovative products. Therefore, the effective extraction of rules for organizational modularization is critical for intraproduct cooperation and division of labor. In the innovation network, the loosely coupled organizations should be decoupled into loosely decoupled organizations, i.e., modular organizations, to fully display the efficacy of modularized organizations. From the perspective of intraproduct division of labor, this paper establishes a DDM to map product demands into functional/design modules and transforms the clustered DDM into a DSM. Then, clustering and diagonal recombination were performed to remove the coupling between modules. Under this decoupling strategy, the suitable decoupled organizations were selected according to the actual demand. This paper only considers the decoupling strategies for loosely coupled organizations based on the transfer of product modules. Further discussion is needed for the coupling based on informal social exchanges or that based on trust or noncontractual relationships. The application scenarios of this study can be boiled down to the following two aspects. One is the opening of organizational learning and the innovation scene of knowledge integration, and the other is implementing organizational platform strategy and network strategy.
