ISO 21500:2021 - Project, programme and portfolio management
ISO 21500 was originally published in 2012 as a foundational standard providing high-level guidance on project management. The 2021 revision (officially titled ISO 21500:2021) represents a significant evolution of the standard.
The 2021 update was necessary to align with the modern landscape of project management, which increasingly integrates program and portfolio management. It moves beyond the narrow scope of "projects" to provide a holistic framework for the management of the entire organizational ecosystem.
ISO 21500 is an international standard developed by the International Organization for Standardization (ISO) that provides guidance on project management concepts and processes. Unlike prescriptive methodologies, ISO 21500 offers a high-level framework applicable to any organization—regardless of size, industry, or geographic location.
Many enterprises buy a corporate license that allows distribution across internal intranets.
