Sample implementation schedule:
This is a copy of a recovery plan we had for Austrian Airlines some time ago. It is some sort of a decision making tree how we can make sure that both production and supply can be guaranteed.
You can see the start showing what needs to be done in the first place. Followed by how far production had continued when the PO was placed. In this example you can see that a large part was ready in production. Some parts needed to be finished. Since that could be done in-time we instructed the factory to proceed.
The problem were the serving spoons and -forks. The factory needed two weeks to finish them, coming close to the ETD of the next vessel. In this case we managed, but we had to put the focus on those two items.
This is a relatively simple example. But disasters come in many forms and shapes. What happens if the vessel breaks down? A disaster at the Long Beach harbor? Strikes? Delivery truck having an accident? Storm damage?
The most basic precaution there is, is having a buffer. By the time that volume is consumed we both have figured out what and where the problem is. And how to solve this. Time is essential. A buffer gives us time to breathe and make correct decisions. A buffer costs us money as we are storing in the USA. It costs us storage charges, and there is a lot of money invested in the production and shipment of the actual product that is not being used, but paid by us in advance. But it is money worthwhile spent.
