The kits are racks with fixed positions for various parts. For instance, all metal parts you need for the assembly of a certain type of trailer or machine. You can check for the completeness of the kit in a single look. There is no need to search for all the individual components spread throughout your production facility anymore, all the components are already collected for you. Because every part has a fixed position in the kit identified with a label, you can easily identify which part is which. Even if parts look alike.
Working with kits simplifies order placing, there is no need to order each component separately. Using kits will also help you to minimize inventory, a fixed number of end products can be assembled with each kit. There is no need anymore to work with long part lists in your warehouse.
