What is generally considered a benefit of modular design?

1. Increased complexity

2. High initial costs

3. Flexibility in assembly

4. Lower repair rates

The correct answer is: Flexibility in assembly

Modular design is predominantly recognized for its flexibility in assembly. This benefit arises from breaking down a product into smaller, manageable parts or modules that can be independently constructed, modified, or replaced. When products are designed in modules, it allows for easier assembly since components can be created in parallel and then integrated later in the process. This flexibility not only streamlines manufacturing operations but also enables customization and adaptability, catering to diverse customer needs or changes in market demand. In addition, using modular design can facilitate maintenance and repairs as individual modules can often be replaced or upgraded without impacting the entire system, although this is a separate advantage focused on maintenance. The other options—such as increased complexity and high initial costs—do not typically represent the hallmark advantages of modular design, as the aim is to simplify the assembly process and maker production more efficient. Lower repair rates may be an indirect benefit, but flexible assembly remains the standout feature of modular design.
