The diagram demonstrates the process of consumer goods production in an orderly manner, including feedback, which enables a company to make some improvements at earlier stages.
Overall, it can be seen that manufacturing consists of two main parts: the first one deals with the production of a commodity, and the second one implies the flow of information feedback and further changes.
The work is initiated with the purchase of raw materials and manufactured components, which are kept in storage. It is followed by production planning, which involves product research and design. At the next step, the items are assembled, inspected, tested, packaged, and dispatched for sale to consumers.
Regarding feedback, it becomes relevant after planning to assess the quality of storage. Likewise, testing and market research allow to evaluate the design; the latter also informs how effective advertising and packaging are. At the sales stage, all the gathered information is used to adjust a product planning and market research.
