Cost reduction is the process used by organisations aiming to reduce their costs and increase their profits, or to accommodate reduced income. Depending on a company’s services or products, the strategies can vary. Every decision in the product development process affects cost: design is typically considered to account for 70–80% of the final cost of a project such as an engineering project[1] or the construction of a building.[2] In the public sector, cost reduction programs can be used where income is reduced or to reduce debt levels.[3]
