ANALYSIS OF FUNCTIONAL REFERENCE ARCHITECTURE THROUGH AN INDUSTRY LENS

Abstract There is an inherent tension between functional descriptions of products and structural descriptions. Traditionally system architecture combine the two, by mapping elements to functions. In this process fundamental decisions about embodiment a product are often taken without proper scrutiny. Axiomatic design advocates zigzag decomposition break down. While approach makes sense for ab initio these rare most developed incrementally., This paper takes up idea reference architecture. Conventional modelling hierarchical into sub function. By contrast FRAs decompose function chain, i.e., dependent sequences required carry out overall allows identification common sub-functions in different chains, thereby generates lattice structure functions rather than tree. enables detailed but solution neutral description product. concept has attracted interest industry does not have many tools methods develop FRA. The discusses some areas that require research
