Production planning assumes two inputs:
Production for customers means that the customer requires certain technical parameters and the product is custom-made, or the product is not in stock and the customer requires a certain delivery date.
Production for warehouse assumes production of a standard product which is distributed to individual customers from the warehouse, to ensure a minimum delivery time.
In both cases, production process of a product goes through the following states:
In order to start product manufacturing, it is necessary to have a filled out product card. The product card contains the technical parameters of the product as well as individual production activities, which need to be done.
Once the production manager knows what products to produce, it is necessary to assemble a production plan. To set up the production plan correctly, the production manager needs to know the following:
If the inputs defined above are known, then it is necessary to schedule the individual tasks into the correct shifts and days so that the orders can be delivered on time according to the customer's requirements. Production managers usually use 14-day production plans, but it depends on the complexity of the products.
During the implementation of the production plan, it is necessary to define production controls, which tell whether the production is going well. By default, manufacturing departments use input material control, output quality control and quality control during storage.
If all the production controls pass, then it is possible to move the product to the Done state and the representative will start planning the transport. Alternatively, the storekeeper takes the product to the warehouse.
