Do new product development managers in large or high-market-share firms perceive marketing-R&D interface principles differently?

There have been many studies on the technical and marketing aspects of new product development. Some studies have pointed out product development activities whose successes can be attributed to the effective combination of technical and marketing activities. However, previous research has also shown the near-impossibility of combining these activities in the product development process. A survey of managers' perceptions of new product principles in the academic literature is conducted.
