ISO/IEC 26550:2013 provides a reference model consisting of an abstract representation of the key processes of software and systems product line engineering and management, and the relationships between the processes.
In the product line there are two development lifecycles (domain engineering and application engineering), the involvement of variabilities, and two process groups ( ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
