| Abstract: | In the field of technology policy, few challenges are more intriguing than understanding the nature of technical and market trends. This paper deals with this problem by using the sociotechnical constituencies approach in order to integrate the treatment of “micro”/“macro” issues — from product to industry. The case study is that of the microprocessor industry where at present a Risc (reduced instruction set computer) technology is emerging in a field where a powerful and far-from-exhausted Cisc (complex instruction set computer) technology tends to occupy almost every segment of the market. The analysis reveals how emerging product-constituencies do implement pro-active trend-creating strategies in order to establish themselves as industrial trends, and, by so doing, they simultaneously re-define the existing content of the “macro” industrial level. The study also reveals the important role of the nature and maturity of microprocessor technology in conditioning the constituency-building strategies implemented by different players. Microprocessor technology is specifically characterised as an architectural, codified-knowledge component with indirect network externalities and weak appropriability regime. Finally, the paper also highlights the potential risks of both fragmentation and complete proprietary control of technology in technological processes involving strongly competitive situations. |
