What is one benefit of modularity in product design?

One significant benefit of modularity in product design is that it allows for easier repair and customization. When products are designed using modular components, these individual parts can be replaced or upgraded independently without having to replace the entire product. This modular approach not only simplifies repairs since a technician can access specific modules rather than the whole system, but it also enables users to personalize their products according to their specific needs or preferences.

For instance, in electronics, a modular smartphone might allow a user to switch out the camera module for an upgraded version without needing to buy an entirely new phone. This flexibility enhances the product's lifespan and can lead to greater customer satisfaction, as users can tailor their products more closely to their desires.

In contrast, the other options represent drawbacks or challenges associated with product design, such as increased design time and higher production costs, which do not align with the benefits of modularity. Similarly, a more complex assembly process can lead to potential issues in manufacturing and user experience, which is contrary to the advantages that modularity aims to provide.
