We found three types of changes, that affects product development related processes, and four important factors to which companies are paying attention while integrating social media into NPD process: (1) frequent interaction with customers, (2) open information flow, (3) building a unit for coordinating activities, and (4) dividing R&D into units for tackling with ideation, concept development, and actual product building separately.
