PurposeThe purpose of this research is to determine how managers’ decisions to discontinue products may be affected by their cognitive and demographic characteristics. Research in product management and entrepreneurship has primarily focused on the introduction of innovations and the marketing of emerging and existing products in the marketplace. Considerably less research has focused on product elimination and how marketing managers decide to remove poorly performing products from a given product portfolio. Nevertheless, product elimination decisions are critical to maintaining business health and protecting firm profits, and are a commonly encountered decision for entrepreneurs and managers of existing products. This study empirically explores the role of factors that may affect a manager's decisiveness in eliminating poorly performing products from a product portfolio.Design/methodology/approachUsing a simulated business environment, this study empirically explores the role of factors that may affect a manager’s decisiveness in eliminating poorly performing products from a product portfolio. Product portfolio decisions are presented to a sample of emerging managers using a computer simulation, and the impact of manager characteristics, namely, cognitive style, gender, academic profile and entrepreneurial intentions on product elimination decisiveness is examined using regression analysis.FindingsThe findings indicate dominant effects for cognitive style and academic profile in driving the decisiveness of product elimination decisions.Research limitations/implicationsThe findings highlight the importance of the academic profile and cognitive style of those entrusted with managing product portfolios, especially as is related to product elimination decisions.Practical implicationsThe findings imply a need for determining the optimal fit of candidates for product portfolio management roles, based on factors such as cognitive style, academic performance and academic area of specialization.Social implicationsGiven the role of entrepreneurial enterprises in enabling social equity, this research highlights the need for entrepreneurial education focusing not only on product introduction but also product omission.Originality/valueThis research expands prior research findings on innovation, promotion and elimination of products by asking what happens at the end of a product’s life when the prospects for a product are no longer strong. The research shows that some managers are less decisive and therefore may be challenged when handling product portfolios with sub-performing products. The findings indicate cognitive and academic influences on product elimination indecisiveness and open new avenues for further examining similar influences in managerial decision-making. This line of work therefore encourages inquiry into the drivers of the important decision of product elimination.
