Model Notes
The acquisition process consists of three sequential steps.
1. Acquisition initiation
2. Procurement (one or more)
3. Acquisition completion.
These individual process steps are discussed in more detail in the paragraphs below.
Target domain and service domain
In ISPL the terms target domain and service domain are used quite frequently.
Target domain: The target domain is the part of the customer organization that is affected by the
service.
Service domain: The service domain is the service organization that delivers the service, i.e., the
supplier.
Acquisition initiation
The first process to be executed by the customer contract authority within an acquisition is the
acquisition initiation process. It consists of two sequential process steps: acquisition goal definition
and acquisition planning. The final result of the process is an acquisition plan reflecting an acquisition
strategy, along with a clear understanding of systems and services requirements defining the
acquisition goal.
Acquisition goal definition
Acquisition goal is clear understanding of the requirements to the systems and services which are the
goal of the acquisition and the costs and benefits for the business and its various stakeholders. This
process consists of four activities:
1. Define the target domain.
2. Refine the definition of the acquisition goal in terms of systems and services requirements.
3. Analyse costs and benefits.
4. Analyse stakes and stakeholders.
Acquisition planning
The goal of this phase is to define an acquisition strategy adapted to the situation, plan the main
decision points of the acquisition, and establish the acquisition organisation. The acquisition planning
phase consists of the following activities:
1. Determine overall service delivery scenarios.
2. Analyse risks.
3. Design acquisition strategy within the risk management framework.
4. Plan the main decision points of the acquisition.
5. Setting-up the customer organisation within the acquisition.
Steps two to four are discussed in detail in the chapter, Managing Risks and Planning Deliveries.
Both the acquisition goal definition and acquisition planning are activities within the phase of
Acquisition Initiation. A more thorough entry of this phase can be found here.
Procurement process
The procurement step of the ISPL acquisition process embodies the obtaining of one single contract.
Note that the acquisition itself can contain multiple procurements. Such a contract consists of one or
more projects or ongoing services. The procurement step consists of three sequencing processes:
