Chapter 13, Problem 1RQ

What are the six activities that are conducted on almost every manufactured product?

Expert Solution & Answer
Check Mark
To determine

The activities performed to manufacture a product.

Explanation of Solution

The processing of the material is a sequence of operations used by applying science and technology to convert the semi-finished goods into useful material. The cycle of operation includes steps like, industrial, chemical, and mechanical through which the material is converted into useful goods with a characteristic shape and desired properties. Thus, it is an engineering process of converting raw material into finished goods.

A series of activities performed onto the material during its manufacturing. There are mainly six activities that are performed on almost every manufactured product and they are:

  1. Design: It is the first step of the manufacturing process in this the initial design of the final product is made.
  2. Material selection: After completion of the design, the next step is selecting the proper material to obtain the best final product.
  3. Process selection: The process includes the type of operation or method used to produce the product.
  4. Manufacture: After selecting the method the manufacturing of the product is started by using the same process.
  5. Inspection and evaluation: It includes inspecting the material produced through the above-mentioned process and evaluating its features accordingly.
  6. Feedback: This is the final step in manufacturing any product. In this step, the feedback of every aspect includes during the entire processing is taken into consideration.

Thus, these are some common activities that are performed on every manufactured product or material.
