The amount of goods that are delivered to people and companies is quite high. What we can observe is that we can get multiple deliveries (including mail) a day. It would be better if a local delivery was centralized. The goods arrive to a specific warehouse and then all the goods for the same person/company are delivered together.
Also, to avoid the isses with the person not beeing at home at the delivery time, each person can configure preferred delivery dates and times. The planning system takes it into account and informs the person on exact delivery planned time.
