Setting the right approach for new product development (NPD) in the presence of uncertainty remains an ongoing debate in innovation management. Stage‐gate systems (SGS) and agile methodology (AM) are the dominant approaches. Recently, hybrid approaches (combining SGS and AM) have been proposed. Although these hybrid approaches represent a significant development in NPD, combining them without considering their design principles might lead to contradictory and competing conceptual formulations, thus ...

AbstractAbstractThis study aimed to investigate the effect of a single injection of pilocarpine upon the phenomenon of cortical spreading depression (SD), in adult rats submitted to early malnutrition and/or to REM-sleep deprivation for 72 h prior to the SD-recordings. The SD was recorded continuously for 3-4 h in 13 well-nourished (W) and 15 early-malnourished (M) adult rats. One to two hours after the beginning of the recording session, a sub-convulsing intraperitoneal (i.p.) injection of pilocarpine ( ...

Managers of exploratory projects might face uncertainties over long timeframes at different levels (e.g., project, portfolio, organization, and network). Although literature offers some guidance on how to deal with uncertainties (mainly at the project level), there is a need for more empirical ground and theoretical development of a systemic approach to the management of uncertainties. To fill this gap, this article employs a multiple case approach in two established firms, investigating six exploratory ...

The innovation ecosystem construct has emerged as a promising approach in the literature on strategy, innovation and entrepreneurship. It draws upon former business ecosystem literature. However, the term innovation ecosystem has been employed in very polysemic and sometimes competing ways. Many adjectives used with reference to innovation ecosystems render the consolidation of the construct more difficult - which its characteristics, boundaries and relation with other, to some extent competing, constructs, ...

Real Options (RO) has been indicated to valuate projects with high uncertainty. However, literature points to challenges and asks for an organizational understanding of its use. So: Why do managers search for the RO approach to valuate radical innovation projects? Based on five in-depth case studies, we discuss hidden organizational and managerial issues related to the search for RO to valuate radical innovation. We argue that managers search for RO to cope with the "paradox of organizational fit", ...

The bullwhip effect, or how uncertainty associated with the end customers' demand propagates through the entire supply chain, has been widely discussed in supply-chain management literature. Although there is a well-established research stream on the causes and mitigating factors for the bullwhip effect in forward supply chains, few studies have investigated how this phenomenon manifests itself in closed-loop supply chains. We argue that this phenomenon can affect the supply chain's environmental ...

Research on performance management (PM) of networks and radical innovation has largely developed along two isolated paths. On the one hand, a growing body of knowledge addresses the use of performance management systems in the context of networks (notably for production and incremental innovation). On the other hand, radical innovation scholars have shown how innovation initiatives that are more uncertain demand the use of new approaches (e.g., new project management routines or different evaluative ...

Consider an interorganizational open innovation project, in which different organizations cooperate to generate value for clients or to solve a technological problem. In this setting, both the focal firm and the partners face uncertainties over time (e.g., technological uncertainties, market uncertainties) and, therefore, the performance of the focal firm and the overall interorganizational project depend on that firm's ability to assess potential uncertainties. The process of diffusion of a particular ...

The introduction of supply chain management (SCM) between the 1980s and 1990s represented a breakthrough in the field of management. SCM provides the analytical and theoretical background to design, plan, and manage production activities involving complex chains of firms. Nowadays, both production activities and incremental and radical innovation are organized through complex networks. Innovations, especially radical ones, have unique characteristics related to production flows, which generate new ...

This paper explores how entrepreneurs cope with uncertainty propagation. Drawing on four in-depth inductive case studies of innovation ecosystems, we characterise the phenomenon of uncertainty propagation and the mechanisms by which entrepreneurs might manage the same. The mechanisms are: i) identification of a protected niche; ii) use of cognitive alignment; iii) ...

The transition of the traditional economy towards the circular economy (CE) is strongly linked to the emergence and development of ecosystems that produce a coherent circular value proposition. However, the literature on how firms create and manage circular ecosystems is unclear. We propose a theoretical framework for managing circular ecosystems involving autonomous yet interdependent actors that create and capture circular values. To achieve this goal, we conducted qualitative research through ...

Firms face the challenge of creating and managing global innovation ecosystems (GIEs) to develop radical innovation. In such a situation, focal firms and their partners may deal with global and local uncertainties requiring unique managerial approaches and strategies. Consequently, uncertainty management becomes central to explaining why some ecosystems successfully develop more radical innovations while others fail in a global landscape. Prior research lacks insight into how focal firms orchestrate ...

The innovation process has traditionally been understood as a predefined sequence of phases: idea generation, selection, development, and launch/diffusion/sales. Drawing upon contingency theory, we argue that innovation process may follow a number of different paths. Our research focuses on a clear theoretical and managerial question, i.e., how does a firm organize and plan resource allocation for those innovation processes that do not easily fit into traditional models. This question, in turn, ...

Industry 4.0 and digital technologies might significantly impact resource optimization in a smart circular economy. However, adopting digital technologies is not easy due to barriers that may arise during this process. While prior literature offers initial insights into barriers at the firm level, these studies pay less attention to these barriers' multi-level nature. Focusing only on one particular level while ignoring others may not unleash the full potential of DTs in a circular economy. To overcome ...

Overview Managing an innovation portfolio is crucial for firms looking to foster radical innovation. Radical innovation, however, creates challenges for traditional portfolio management systems. When companies do not adequately distinguish between incremental and radical innovation when designing their management systems, portfolio management decision-making processes will tend to favor incremental innovation. Radical innovation requires a broader, multilevel organizational approach. We propose ...
