Modular design has numerous advantages compared to integral design. Some advantages are listed below:? Minimize cost, by reducing the number of parts.? Savings in design time as their reliability, cost and quality are documented and easily available.? Modular products enable quicker, easier and more efficient customization of standard products.? Modules can be modified or replaced without changing anything else on the product.? Modular design allows quick and easy upgrades.? Modular design decrease obsolescence and shortens the redesign cycle? Easy and quick installation of products as the product has minimum number of parts.? Easy and quick servicing and maintenance of products.? Modular design requires shorter learning time when new employees have to become familiar with products.? Modular design gives businesses the possibility to outsource the assembly of some modules, therefore freeing-up manufacturing capacity and increasing the number of products delivered on time.?
