| # Case assumptions This case makes the following assumptions: The customer is already known from the quotation phase, and does not have to be re-entered in Customer Data Management. The potential iteration in the process to define the final specifications in between the sign-off of the quotation and the issuing of the sales order is not explicitly modelled. All items, including the long-lead-time items, are ordered in the contract-phase. The production of the customized product can only be started after goods that have specifically been ordered for this product are received at the warehouse. The invoicing is usually carried out at several points during an actual project, for example, at contract signing, production start, production finish, and actual delivery. However, in this case, for reasons of simplicity, the case is assumed to only show the invoicing-part of the process at the end of the project. |
