ISO 12207

What is ISO 12207:

The title of standard is “ISO/IEC 12207 Systems and software engineering — Software life cycle processes”

ISO 12207 is an international standard for software lifecycle processes covering all the tasks required for developing and maintaining software. It also includes processes and activities applied in acquisition and configuration of the services of the system.

It defines 43 system and software processes. It recommends the adaption of the set of processes, activities and tasks according to the software project.

Processes are classified in three types:

• basic
• for support
• organizational

The support and organizational processes must exist independently of the organization and the project being executed. The basic processes are instantiated according to the situation.

The major sections of 12207 are:
