Managing knowledge properly has become a necessity in all types of professional activities, especially in those whose products are highly utilised and disseminated, such as software engineering. Because we live in a software-dependent society, this technological development requires improving the processes of understanding and manufacturing; thus, it is recommended to use knowledge as a basis to achieve such improvements. This paper presents the results of an analysis of the proposals to manage knowledge in requirements engineering, in which it is evident that the proposals fail to meet the needs of work teams. The practices evaluated in this study propose an integrated framework for the management of knowledge in RE comprised by the conjunction between the phases of knowledge and the stages of RE and characterised by including two principles of complex thought: transdisciplinarity and multidimensionality.
