1. To increase labor productivity: Automating a manufacturing operation usually increases production rate and labor productivity. This means greater output per hour of labor input.
2. To reduce labor cost: Due to ever increasing labor cost, higher investment in automation has become economically justifiable to replace manual operation.
3. To mitigate the effects of labor shortage: There is a general shortage of labor in many advanced nations and this has stimulated automation.

5. To improve worker safety: By automating a given operation and transferring the worker from active participation in the process to a supervisory role.
6. To improve product quality: Automation not only results in higher production rate than manual operations; it also performs the manufacturing process with greater quality.
7. To reduce manufacturing lead time: Automation helps to reduce the elapsed time between customer order and product delivery.
8. To accomplish processes that cannot be done manually: Certain operations cannot be accomplished without the aid of machine automation.
