Order approval
Order approval is a necessary activity within the framework of production planning and control in order to convert the planned production program into actual and 'feasible' production orders . It forms the transition from the planning or control phase to the actual operational implementation phase. Before the next pending orders are released, the availability of all necessary resources is checked, such as material (raw material, parts , assemblies ), tools , means of transport , machines and suitable personnel (availability check ). The order is only released for execution when all the necessary resources are available.
As a transition from planning to the beginning of implementation, it is of particular importance because changes such as changed requirements , changes in dates or quantities , consideration of changes to production resources can be taken into account in a new planning much more easily during planning than after an order has been released. if order documents have already been created, the source material has already been removed and the first work process has already started or even completed.
The medium-term planned orders sorted according to priority are periodically checked with regard to the arrival of the planned end / start date. If a start date is possible in good time, the orders (after the availability check) are set to the status "released" and all resources required for this are reserved for the order . There are different procedures for this. Either the availability is only examined for the release date or except for a more or less long period between the release and the actual start, i.e. That is to say, an availability that is expected because it is planned is also included. That is why one speaks of static and dynamic order approval.
A special method of order release is the load-oriented order release , which is supposed to do justice to the needs of production control rather than the needs of planning with its inevitable imponderables.
Kanban is a form of order approval based on the pull principle . It pushes prepress orders depending on the actual needs of the downstream, consuming point. Operational control and communication between the parties involved takes place via a (physical or electronic) shuttle card . This process assumes availability and is not checked.
