Kodak has successfully learned the strategy of developing many distinctively different models from a common platform. Between April 1989 and July 1990, Kodak redesigned its base model and introduced 3 additional models, all having common components and common production process steps. The platform approach to product development is an important success factor in many markets. By sharing components and production processes across a platform of products, companies can develop differentiated products efficiently, increase the flexibility and responsiveness of their manufacturing processes, and take market share away from competitors that develop only one product at a time. The fundamentals of platform planning are discussed in detail.
