The domain of New Product Development (NPD) is subject to considerable uncertainties. Aside from market‐related sources of uncertainty, the degree of innovativeness of the underlying product concept is a significant source of uncertainty, as unclear goals and specifications like, e.g. product specifications may lead to substantial delays in the project. However, companies are required to manage the innovation process as efficiently as possible. The resulting conflicting demands often leave companies struggling to achieve both efficiency as well as flexibility due to their often opposing implications for organizing and managing NPD projects. In this context, planning plays a central role; however, its usefulness for NPD project success is perceived quite differently. While there are reports about a positive influence of initial planning on various success measures, others have questioned the effectiveness of elaborated initial planning and contend that the ability to rapidly react to changes later in the process and to improvise may lead to success in NPD. This study aims at achieving a better understanding of planning in NPD by investigating a sample of 475 Research & Development projects in Japanese electrical and mechanical engineering companies. Regression analysis is used to shed more light on the interplay of planning intensity, changes, and the degree of technological newness of the NPD project and their influence on project success. Our results indicate planning to be of value for different types of innovation projects. Furthermore, the influences of the variables in question vary with the success measures that are taken into account, indicating that a more detailed and contingent understanding of planning in NPD needs to be developed.

In this paper, we report on the results of a large-scale study about typical front-end-related innovation practices in 553 Japanese mechanical and electrical engineering companies. We explore typical activities concerning the generation and assessment of new product ideas, the reduction of technological as well as market uncertainty and front end planning. Finally, we report on differences between successful and unsuccessful companies. Our study confirms earlier findings about the frequent use of creativity techniques in Japan during the process of idea generation. We also find companies to intensively involve upper management and customers into NPD projects. While integrating upper management is of vital importance for assessing new product ideas, integrating customers and users is primarily used to developing product ideas and concepts . We further find evidence that successful companies integrate their customers more frequently in the process of developing and assessing new product ideas than non successful companies. In addition, the former integrate customer requirements into their product definitions more often and also translate these requirements into technical specifications more frequently than non-successful companies. Finally, successful companies more often systematically plan a project prior to its start than unsuccessful ones. IntroductionIn a comparison of 14 German and 14 Japanese NPD projects, Herstatt et al. (2004: 20) report on front-end related activities in these countries. They found Japanese companies to rely on a comparatively formal approach with strong methodological support to reduce uncertainty. With this paper we try to extend and test their propositions in order to develop a deeper understanding of Japanese front end activities in the context of a large scale study. We will report on findings about typical activities such as idea generation and assessment, and the reduction of market and technological uncertainty. In addition, we will show differences in the practices between successful and unsuccessful companies with regard to the execution of several front end activities.For this purpose, the paper is organized as follows: Part 2 provides an overview of our study describing our sample and addressing methodological issues. We present our findings concerning typical front-endrelated activities in part 3. Next, we report on the differences between successful and unsuccessful companies. This paper ends with a discussion of our results and suggestions for further research. Study Aim of the studyEmpirical work by Cooper and Kleinschmidt showed that "the greatest differences between winners and losers were found in the quality of execution of predevelopment activities" (Cooper and Kleinschmidt, 1994: 26). Two factors were identified as playing a major role in product success: the quality of executing the pre-development activities, and a well defined product and project prior to the development phase (Cooper and Kleinschmidt, 1990: 27).A study of 788 new product launches in Japan con...

Users are the primary source of new techniques, i.e. systematic activities by which a complex task is accomplished. Even though user-generated techniques are a pervasive phenomenon which can be observed in many different contexts, existing research on user innovation has focused on product and service innovations. We focus on this important area of user innovation by studying four cases in the field of medical devices to analyse the processes by which users generate and diffuse new techniques as well as the interdependencies between usergenerated techniques and subsequent changes to product use and product innovation. Our findings suggest that user innovation in techniques triggers product innovation by users and manufacturers. Therefore, users' contributions to total innovation output are much higher than previously considered. Additionally, the diffusion of techniques differs significantly from the diffusion of new products. It can only be achieved with the involvement of diffusion agents and their interpersonal interaction and joint performance of the technique with possible adopters. As the diffusion of a technique is often a prerequisite for the diffusion of any related product, companies are forced to re-think their marketing strategies.
