The flowchart illustrates the process of producing plastic paper clips in three different colours at a small manufacturing facility.
Overall, molten plastic is moulded into red, blue, and yellow clips, which then undergo two stages of quality control and manual sorting. While only clips that pass both inspections are packaged and dispatched, defective ones are rejected.
At the beginning of the process, molten plastic is poured into three moulds to produce red, blue, and yellow paper clips. These are subjected to an initial quality control stage in which machines test their strength. Any items that fail this assessment are discarded.
In the following step, the clips are sorted manually into two groups: single-colour and mixed-colour products. Both categories are then inspected again to confirm their suitability. Once this final quality check is complete, the acceptable clips are packaged and prepared for distribution, while substandard ones are removed from the process.
