Statistical Quality Control is the process managers use to continually monitor all phases of the production process to ensure that quality is being built into the product from the beginning and that quality is not being inspected into the product at the end of the production process.
All products go through a quality control procedure to make sure their products meet industry and company standards. Organizations do this to ensure they are putting out the smallest amount of defects as possible when creating items to sell to wholesalers or consumers.
