A Causal Model of the Impact of Skills, Synergy, and Design Sensitivity on New Product Performance

Abstract

Notwithstanding the best efforts of outstanding managers, project team members, researchers, and consultants, no product development plan can guarantee success. Every new products organization will experience its fair share of failures, but a firm can take steps to ensure that its failures do not outweigh its successes. By benchmarking the competition, a firm can gain insight into best practices–the factors that lead most directly to new product success. To help identify these best practices, X. Michael Song, William E. Souder, and Barbara Dyer develop and test a causal model of the relationships among the key variables leading to new product performance. The proposed model identifies five factors that lead to marketing and technical proficiency: process skills, project management skills, alignment of skills with needs, team skills, and design sensitivity. According to the model, marketing and technical proficiency directly determine product quality, and ultimately lead to new product success or failure. The causal model was tested using information on 65 completed projects–34 successes and 31 failures–from 17 large, multi‐divisional Japanese firms. The study participants develop, manufacture, and market high‐technology consumer and industrial products. These firms judged the success or failure of the projects in this study by using seven criteria: return on investment, profit, market share, sales, opportunities for technical leadership, market dominance, and customer satisfaction. These firms generally assigned the greatest importance to customer satisfaction, opportunity creation, and long‐term growth. For the most part, the responses from these firms support the relationships presented in the causal model. According to the respondents, marketing proficiency and product quality have a strong, positive influence on their new product performance, as do process skills, project management skills, and alignment of skills and needs. The responses highlight the importance to these firms of responsiveness to customer wants and needs, as well as ensuring a close fit between project needs and the firm's skills in marketing, R&D, engineering, and manufacturing. Somewhat surprisingly, the responses do not support the model's suggested relationships between skills/needs alignment and technical proficiency or between technical proficiency and product quality.
