This work presents a conceptual proposal about the genesis and management of sectorial technology chains and their application in the development of new products. The proposal is based on the identification of knowledge and convergent technologies within the process of innovation technology, considering the study of existing products and processes and the analysis of technological and marketing trends. We report on a case-study based research carried out in Colombia on biopolymer chitin and chitosan applications. We also present a set of criteria for the integral evaluation of ideas and product concepts with potential for developing technological innovation.
