The product process matrix (PPM): Definition, examples, and template

The product process matrix (PPM), introduced by Robert Hayes and Steven Wheelwright, is a framework that visually represents the relationship between product development and the production process lifecycle, focusing on product volume and customization. Initially designed for manufacturing, the PPM is adaptable for software product management, offering insights into production processes and helping managers make informed decisions on resource allocation, product strategy, and development. It identifies five types of production processes: job shop, batch, assembly line, continuous, and flexible manufacturing systems (FMS), each suited to different levels of customization and production volume. The PPM also aids in identifying production bottlenecks, optimizing processes, and ensuring product-market fit by aligning production strategies with market needs. While its static nature and manufacturing focus are limitations, adapting the PPM for software can enhance collaboration among cross-functional teams and improve overall efficiency and product quality.
