Implications of interface management for modularity degree

Purpose – The purpose of this paper is to demonstrate modularity degree in terms of interfaces and innovation. Design/methodology/approach – 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. Findings – 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. Research limitations/implications – 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. Practical implications – 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. Originality/value – 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.
