In this paper; it discusses about a multidimensional framework that enables comprehensive product architecture assessment. Considering todays market situation, where the product lifecycles have drastically been reduced; the concept of 3D-CE (3-Dimensional Concurrent engineering) is being used which is based on component commonality, product platforms, and product modularity. The paper also discusses about examples where this framework can be used to focus on operational strategy decisions like product design, architecture and dimensions; or to address limitations and advantages of an operational strategy for given specifications or to develop dynamic capabilities such as planning effective productoperation strategy combinations.The paper describes product architecture as a comprehensive description of a bundle of product characteristics, including number and type of components, and number and type of interfaces between those components, and, as such, represents the fundamental structure of the product.Decisions in product development are generally in 3 domains: Product, Process and Supply Chain. To analyze the effect that individual product architecture characteristics exert on different decisions across the domains; different models have been developed and the author categorizes them into: Mathematical, Conceptual, Engineering Models.The Product Architecture assessment at an operational level can be done on attributes like product function, product components, function-component allocation (FCA) scheme [Dimension 1]; or interface characteristics like interface type, interface reversibility or interface standardization [Dimension 2]
