What is modularity?

Modular product architecture is the foundation for tailoring a product to the needs and requirements of your customers.

As an example, product X is composed of 20 separate modules – each module available in five different variants. If the modules have standardized interfaces, each variant may be combined to build different product models. Combining these variants in different ways creates an almost limitless number of product configurations.

The secret to success is maintaining your interfaces. That is the core of modular design that enables mass customization.
