3.1. Process reference model‌

Processes are collected into process groups according to the domain of activities they address.

These process groups are organized into 3 process categories: Primary life cycle processes, Organizational life cycle processes and Supporting life cycle processes.

For each process a purpose statement is formulated that contains the unique functional objectives of the process when performed in a particular environment. For each purpose statement a list of specific outcomes is associated, as a list of expected positive results of the process performance.

3.1.1. Primary life cycle processes category‌

The primary life cycle processes category consists of processes that may apply for an acquirer of products from a supplier or may apply for product development when responding to stakeholder needs and delivering products including the engineering processes needed for specification, design, implementation, integration and verification.

The primary life cycle processes category consists of the following groups:

 the Acquisition process group;

 the Supply process group;

 the System engineering process group;

 the Validation process group;

 the Software engineering process group;

 the Machine learning engineering process group and

 the Hardware engineering process group.

The Acquisition process group (ACQ) consists of one process that is performed by the customer, or by the supplier when acting as a customer for its own suppliers, in order to acquire a product and/or service.

Table 3 — Primary life cycle processes – ACQ process group

The Supply process group (SPL) consists of one process performed by the supplier in order to supply a product and/or a service.

Table 4 — Primary life cycle processes – SPL process group

The System Engineering process group (SYS) consists of processes addressing the elicitation and management of customer and internal requirements, the definition of the system architecture and the integration and verification on the system level.

Table 5 — Primary life cycle processes – SYS process group

The Validation process group (VAL) consists of one process that is performed to provide evidence that the product to be delivered satisfies the expectations for its intended use.

Table 6 — Primary life cycle processes – VAL process group

The Software Engineering process group (SWE) consists of processes addressing the management of software requirements derived from the system requirements, the development of the corresponding software architecture and design as well as the implementation, integration and verification of the software.

Table 7 — Primary life cycle processes – SWE process group

The Machine Learning Engineering process group (MLE) consists of processes addressing the management of ML requirements derived from the software requirements, the development of the corresponding ML architecture, the training of ML model, and testing of ML model against ML requirements.

Table 8 — Primary life cycle processes – MLE process group

The Hardware Engineering process group (HWE) consists of processes addressing the management of hardware requirements derived from the system requirements, the development of the corresponding hardware architecture and design as well as the verification of the hardware.

3.1.2. Supporting life cycle processes category‌

The supporting life cycle processes category consists of processes that may be employed by any of the other processes at various points in the life cycle.

Table 10 — Supporting life cycle processes - SUP process group

3.1.3. Organizational life cycle processes category‌

The organizational life cycle processes category consists of processes that develop process, product, and resource assets which, when used by projects in the organization, may help the organization achieve its business goals.

The organizational life cycle processes category consists of the following groups:

 the Management process group;

 the Process Improvement process group;

 the Reuse process group.

The Management process group (MAN) consists of processes that may be used by anyone who manages any type of project or process within the life cycle.

Table 11 — Organizational life cycle processes - MAN process group

The Process Improvement process group (PIM) covers one process that contains practices to improve the processes performed in the organizational unit.

Table 12 — Organizational life cycle processes - PIM process group

The Reuse process group (REU) covers one process to systematically exploit reuse opportunities in organization’s product portfolio.
