Planning for Product Platforms

This is an MIT Sloan Management Review article. By sharing components and production processes across a platform of products, companies can develop differentiated products efficiently, make their manufacturing processes more flexible, and take market share away from competitors that develop only one product at a time. The platform approach also enables companies to manufacture products in high volumes that are tailored to meet the needs of individual customers. A platform is a collection of assets--components, processes, knowledge, people, and relationships--that a set of products share. The platform planning effort involves two key tasks. First, product planning, where marketing managers determine which market segments to enter, what the customers in each segment want, and what product attributes will appeal to those customers. Second, system-level designers decide which product architecture to use to deliver the different products while sharing parts and production steps across the products. Three key ideas underlie the platform planning process. First, customers care about distinctiveness, how closely the product meets their needs. At the same time, the cost of a firm's internal operations is driven by the level of parts held in common among a group of products. Second, given a particular product architecture, there is a trade-off between distinctiveness and commonality. Third, product architecture dictates the nature of this trade-off. By developing and aligning three tools--a product plan, a differentiation plan, and a commonality plan--managers can balance the need for distinctiveness with the need for commonality. The process must involve all key functions and be guided by top management.
