Define requirements The definition of requirements is out of the scope of ISPL. For more information on defining requirements I would like to refer to the entry on Requirements management processes. Specify deliverables Both customer and supplier organisation have to specify the information and services they want to receive from the other party. More information on the specification of deliverables can be found in the chapter on #Specifying Deliverables. Situation Analysis, Identify Risks, Select Strategy The customer organisation has to conduct a situation analysis to be able to identify critical risks and mitigate them using an appropriate delivery strategy. More information can be found in the chapter '#Managing Risks and Planning Deliveries'. Make decisions During the execution of the delivery plan the customer and supplier make decisions at each decision point. This is the #Contract Monitoring phase. Acquisition Process Sequence This chapter provides a high-level description of the ISPL acquisition process from a customer-supplier-interaction point-of-view. Figure 3 illustrates the sequence of customer and supplier processes during the acquisition. The following paragraphs link the processes in Figure 3 to the theoretical information that is present in this entry and thus provide a link from practise to theory. Make RFP To construct a request for proposal the customer first needs to describe the acquisition goal and other requirements, and perform a situation and risk analysis. Using the risk analysis a delivery plan has to be constructed. More information on all of these activities can be found in the chapter #Managing Risks and Planning Deliveries and the paragraph #Acquisition initiation in the chapter #Managing Acquisition Processes. The request for proposal is a #Tendering deliverable. Make proposal The supplier company writes a proposal in which it clarifies how it can fulfil the acquisition goal. More information on proposals can be found in the paragraph #Tendering deliverable. Select The customer selects a supplier. The selection activity is an important step in the #Tendering process, part of the #Procurement process. Negotiate contract Customer and supplier negotiate the contract. Usually this means that the delivery plan is refined to a more detailed level. The information in the chapter #Managing Risks and Planning Deliveries can be used to update the delivery plan. Make decisions For each contract the delivery plan is executed. Customer and supplier make decisions at each decision point. For an individual contract the final decision is whether #Contract Completion is reached. The deliverables used in
