Reducing handoffs is one of the change concepts for simplifying a process. Similarly, reducing the number of component parts is a way to simplify a product. Benefits accrue to manufacture, to the customer, and to those repairing or maintaining the product. Components in this context can mean component parts, ingredients, or multiple types of the same component.

Reduction of components can be achieved in different ways. One way is through design of the product so that one component performs the functions previously performed by more than one. Another method is to standardize the size, shape, or brand of similar components. A third method is to package components into modules.
