Commonality is the degree or extent to which an item is interchangeable or can be used in multiple products. For instance, audio compact discs (CD) work with CD players, DVD players, Blu-ray players, laptops, desktops, etc. An audio CD’s compatibility with multiple technological devices is its commonality.
Commonality in the Manufacturing Industry
Commonality, within the manufacturing realm, means the flexibility and freedom to use same components for different products, which helps simplify the control and management of resources. Commonality also assists with decreasing setup time, and increased flexibility and productivity. For example, standardization of vehicle parts such as wheels, axles, etc. help with mixing and matching components and reducing costs. Overhead costs, to a great extent, go up with the increasing number of components handled.
