Assembly processes can greatly impact the cost-effectiveness of a product. In house assemblies can cause a waste in man power and otherwise useful resources which are taken over by the process. The assembly process takes resources and logistical planning which can be better utilized in other areas. Lean Manufacturing techniques are important to an effective assembly process to help maintain maximum profitability without sacrificing quality of the end product.

Eliminating sub-assembly processes can result in reduction, or in some cases elimination, of associated costs.
