3.1. Process reference model

Processes are grouped by process category and at a second level into process groups according to the type of activity they address.

There are 3 process categories: Primary life cycle processes, Organizational life cycle processes and Supporting life cycle processes.

Each process is described in terms of a purpose statement. The purpose statement 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 be used by the customer when acquiring products from a supplier, and by the supplier when responding and delivering products to the customer including the engineering processes needed for specification, design, development, integration and testing.

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 Software engineering process group.

The Acquisition process group (ACQ) consists of processes that are 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 2 — Primary life cycle processes – ACQ process group

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

Table 3 — 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 testing on the system level.

Table 4 — Primary life cycle processes – SYS 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 testing of the software.

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.

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, will 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 7 — 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 8 — Organizational life cycle processes - PIM process group

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