The role of openness in the fuzzy front-end of service innovation

The early stages of innovation involve high levels of uncertainty, leading to it being labelled as the “fuzzy-front end” (FFE). Although openness has been identified as pivotal to innovation performance in the open innovation literature, little effort has been put into exploring its role in the FFE. Specifically, this study examines ‘openness competence’ within the FFE–i.e., the ability of a FFE team to explore, gather and assimilate operant resources from external sources by means of external searches and inter-organisational partnerships. The aim is to investigate the impact of openness competence on front-end uncertainty reduction and service innovation success. Data were obtained from a survey of 122 IT-based service innovation projects implemented by IT service provider firms in Thailand. The results suggest that openness competence positively influences both the degree of uncertainty being reduced during the FFE and the overall success of service innovations. These findings offer several implications for research on open innovation and the FFE as well as encouragement to managers to apply a more open approach to the FFE of their service innovation projects.

From innovation to market entry: a strategic management model for new technologies

In this paper, we introduce a new framework that generates a list of strategic actions to support successful management of the innovation process as new technologies are taken to market. The framework links different stakeholders inside and outside the organisation to obtain an holistic view of the requirements necessary to develop the new technology. It integrates and synthesises existing frameworks into an inclusive set of guidelines. The framework is then tested in a case study located in a mid-size semiconductor organisation currently seeking new business opportunities in the emerging photovoltaic market. We conclude by reflecting on the usefulness of the model. Theoretically, the paper contributes to the literature on the management of the introduction of new technologies; practically, the framework provides a normative tool for practising managers.

Removing the fuzziness from the fuzzy front-end of service innovations through customer interactions

Customer interaction in new service development has a positive impact on the performance of new services. In addition, prior studies recognize the importance of the fuzzy front-end stages of new service development. Yet, the researchers have not taken the next step to explore the relationship between these two key areas of service innovation. To address this critique of the literature, the process of customer interaction in the fuzzy front-end of new service development is investigated by conducting a rigorous qualitative field research involving 26 financial services firms. The findings suggest that the fuzzy front-end can be much less ‘fuzzy’ if customers are involved in the front-end stages of new service development.
