This work reports on the associations between a variety of factors related to the adoption and use of 76 well-known new product development (NPD) tools on NPD performance at the project level in small high technology firms. The specific factors of interest are determinants of tool adoption, tool diffusion, thoroughness of use, flexibility of use, tool adaptation, user familiarity with tools, and tool satisfaction. The results provide managers and practitioners with several useful tool guides, benchmarking tables and models to aid in the selection and use of tools in NPD projects of any type.
