Introducing Interface Management in New Product Family Development

Abstract Creating product platforms from which many products can easily be leveraged is an issue of increasing concern for many companies. This article introduces and explores the concept of interface management (IM) in new product platform development. IM is the distinct process of developing and defining the physical platform interfaces. The concept of IM is empirically explored in two product family development projects in the Swedish manufacturing industry that have been longitudinally studied for more than 3 years. It is proposed that firms which have a product family development approach that is associated with an extensive IM process enjoy a high degree of freedom in deciding how to balance its time to market for individual products with the beneficial utilization of design familiarities across all products. Moreover, if product managers understand and explicitly focus on the IM process, the often challenging shift from a single product development approach to a product family development approach is likely to be facilitated.
