Increasingly, marketers rely on advances in technology to maintain competitive parity or gain competitive advantage. Yet, often, the adoption of technology is met with suboptimal results and even outright failure. Qualitative field research based on depth interviews with business managers responsible for technology adoption decisions within their respective firms is used to develop a theoretical framework explaining the technology adoption process within firms, how expectations are formed for the innovation’s performance and factors that can further influence those perceptions. Result suggest a firm’s dynamic capabilities play a central role in informing the firm’s perceptions of a technological innovation’s characteristics that drive the adoption decision. Findings also suggest that a firm’s expectations are influenced by perception of risk, internal micro-political actions, and the opportunity to observe or trial use of the technological innovation.

While innovation contests and intermediaries are widely used in large companies to source knowledge from the outside, it is not clear how contests could be utilized to break the barriers that SMEs face in pursuing Open Innovation. In this paper, we shed light on the topic by analysing ten innovation contests that have been successfully run in three European countries with the specific aim to create innovation opportunities between SMEs and higher education institutions, research centres, other companies, or end users. The analysis resulted in the identification of common elements that played a crucial role in these innovation contests, but were overlooked in previous research. Moreover, we collected early evidence supporting the case for innovation contests as tools to support Open Innovation policies for SMEs. On that basis, we propose a new framework that can be used by innovation intermediaries to design innovation contests specifically aiming at supporting Open Innovation in SMEs.

In today’s highly competitive business environment, firms can ill afford the consequences of overlooking opportunities for innovation. An organization seeking to increase its existing knowledge base, in most cases, aims to identify and pursue useful knowledge available outside its borders. However, for companies interested in engaging in collaborative arrangements for innovations, systematic approaches for knowledge transfer may become a major challenge. In our research we focus on the diffusion of innovative knowledge that occurs during a joint knowledge development process. We present an empirical study spanning the period 2004 to 2018 which aims to explore the impact inter-organizational collaboration in the form of joint patenting has on the distance between partners’ technological bases. In addition, this paper looks into the change in technological distance when joint patenting occurs between different-country and same-country partners. The empirical results of the study suggest that engagement in joint patenting positively influences the technological proximity between partners and indicates a transmission and utilization of knowledge outside of firms’ existing knowledge base. Our findings contribute to knowledge related to innovation under inter?organizational collaboration and provides a basis for further theory development and testing.

When the COVID-19 pandemic hits Portugal in early March 2020, medical doctors, engineers and researchers, with the encouragement of the Northern Region Health Administration, teamed up to develop and build, locally and in a short time, a ventilator that might eventually be used in extreme emergency situations in the hospitals of northern Portugal. This letter tells you the story of Pneuma, a low-cost emergency ventilator designed and built under harsh isolation constraints, that gave birth to derivative designs in Brazil and Morocco, has been industrialized with 200 units being produced and is now looking forward to the certification as a medical device that will possibly support a go-to-market launch. Open intellectual property (IP), multidisciplinarity teamwork, fast prototyping and product engineering have shortened to a few months an otherwise quite longer idea-to-product route, clearly demonstrating that when scientific and engineering knowledge hold hands great challenges can be successfully faced.

This paper develops a conceptual model for finding key factors for new product development (NPD) evaluation. It builds on the work of the most cited and published authors on innovation management, but transfers attention from advertising aspects and efficiency, to factors identified within the NPD process such as new product project definition, a firm’s resources, organisation-product fit, and commercial entity, that would lead to success with “Information acquired” being identified as the underlying key factor. This paper presents a summary of the results of correlation coefficients calculated between the factors identified and outcome measures, derived from the leading authors’ work. Further, analytic hierarchy process (AHP) was used to evaluate the results of the correlation coefficients of sub-factors, which were modified by considering the ranking of each author.

With the discovery of the Pre-Salt reserves, exploration of oil and gas is being strongly extended in Brazil, contributing to the recent increase of the demand for drilling capabilities. This paper discusses the impact of this oil discovery by assessing the relationship among the growth of proven reserves, the financial position of firms, and patent applications in the Brazilian upstream oil and gas industry. We provide empirical evidence indicating that firms with a lower financial performance prior to the pre-salt discovery were more aggressive in increasing the number of patent filings addressing technologies of the upstream oil and gas domain.

This study has explored the impact of innovation hubs on knowledge, innovation and entrepreneurial ecosystems. To gain deeper insights, the study adopted an exploratory case study design along a qualitative approach to conduct an empirical investigation. The study reveals a noticeable contribution of the X-Innovation Hub in empowering youths in aspects of knowledge co-creation and transfer, and promotion of diverse innovations. The findings of the study also disclose that the contribution of the innovation hub in transforming innovations into entrepreneurial opportunities is still unsatisfactory. Furthermore, the findings suggest that not all start-ups emanating from the hub are taking off. This is due to various undermining factors such as financial constraints and unfriendly legal frameworks. For X-Innovation Hub to satisfactorily and sustainably contribute to national innovation systems, deliberate efforts must be made, and strategies put in place by different stakeholders such as the government. Particularly, diversification of funding sources to minimise dependence on international development funding agencies and organisations is important.

Social innovations are important tools for minimizing or solving social problems. However, significant challenges remain in managing social innovation development for long-term survival and expanding its social impacts to generate scalability. This process can be supported by dynamic capabilities and their microprocesses. By conducting a single case study, we aim to contribute to the stream of research on management of social innovation that analyzes the ways in which dynamic capabilities can influence the scalability process of social innovation. Our contribution arises from generating an understanding of how and why dynamic capabilities influence the social innovation scalability process.

Companies are increasingly adopting open source strategies to develop and exploit complex infrastructures and platforms that combine software, hardware and standard interfaces. Such strategies require the development of a vibrant ecosystem of partners that combines the innovation capabilities of hundreds of companies from different industries. Our aim is to help decision makers assess the benefits and challenges associated with creating or joining such ecosystems. We use a case study approach on six major collaborative ecosystems that enable the development of complex, high cost infrastructures and platforms. We characterize their strategy, governance, and their degree of intellectual property (IP) openness. We offer a three-dimensional framework that helps managers characterize such ecosystems. Although all the ecosystems studied aim at scaling up innovative solutions, their strategy, governance and IP openness vary. An upstream strategy aimed at replacing supplier proprietary design with open substitutes requires a democratic governance and an intellectual property policy that maximize the attractiveness of the ecosystem. A downstream strategy aimed at carving a space in new markets requires an autocratic governance and an intellectual property policy that combine attractiveness and value capture opportunities.
