| Summary: | Correct product portfolio management is one of the feasible ways of ensuring competitive sustainability before continued market evolution whereby decisions to maintain or exclude an item from the sales offering drives consequences that impact both internal and external contexts. In alignment with this standpoint, the purpose of this study is to identify and pinpoint the conceptual framework on product portfolio management, particularly in as much as existing applications centred on manufacturing sector firms is concerned, so as to allow for the envisioning of possible opportunities of fostering future investigations on the subject matter. To this effect, theoretical-conceptual research was conducted, starting with the primary definition of how this field of study is explored right through to the bibliometric review of existing publications. The end result was the identification a gap in research that focuses on portfolio management at manufacturing companies, particularly in Brazil where only two studies centred on this theme were found, although the country hosts more than 30 types of organizations of this kind.
