在这个实现场景中，设想系统在某一操作发生后，通过各不相同的通讯渠道通知客户。

For this implementation example, let's imagine a system that, upon some action taken, notifies customers via disparate communication channels.

如果任何一家制造厂拒绝或无法处理订单，那么这批订单的整个制造流程就会撤消，并且系统会向客户通知这个问题。

If any of the manufacturing plants reject or fail to process an order, then the complete manufacturing process for the batched orders is revoked, and the system notifies the customer of the problem.

如果客户在auditor 1批准之前取消请求，系统只需要发送一个取消通知给auditor 1作为补偿。

If the customer cancels the request before auditor1 approves the request, the system only needs to send a notice to auditor1 about the cancellation as the compensation.
