The model above is the same as the kosher IDEF0 model except for small changes. The diagram giving the expansion for orders is included on the right hand side of the bottom level of the model (thus extending the bottom level from four to five diagrams). Links from this diagram to the diagrams for the activities, order supplies and deliver supplies, are provided by relabelling two lines and adding one line to those diagrams.
