manufacturability and value engineering.

Explanation:

Manufacturability and value engineering are processes that are concerned with improvement of specifications and designs at the stages of research, development, design, and production.

Value engineering aims to increase the value of a good by analysing the function. Value is the ratio of function to cost, so when we want it increase value we either increase function or reduce cost.

Manufacturability and value engineering involves reduction of the complexity of a product and improving a product's maintainability for use.
