ISO 21500:2021 – Project, Programme and Portfolio Management: Context and Concepts

1. Definition

ISO 21500:2021 is an international standard that provides guidance on project, programme, and portfolio management, describing their key concepts, relationships, and governance principles.
It establishes a unified framework for managing projects and programs effectively across different sectors, ensuring that strategic objectives are achieved through coordinated planning, execution, and control.

ISO 21500:2021 supersedes the earlier ISO 21500:2012, expanding its coverage beyond projects to include programmes and portfolios, and strengthening alignment with other management system standards such as ISO 9001 (Quality), ISO 31000 (Risk), and ISO 55001 (Asset Management).

2. Purpose and Scope

The primary purpose of ISO 21500:2021 is to:

• Define the fundamental principles and concepts of effective project, programme, and portfolio management.

• Provide a common language and structure for organizations, practitioners, and stakeholders.

• Support the integration of management practices across organizational levels.

• Promote governance, accountability, and transparency in project-oriented organizations.

• Serve as a foundation for related standards, including ISO 21502 (project management guidelines), ISO 21503 (programme management), and ISO 21504 (portfolio management).

This standard applies to all types of organizations — public or private, large or small — that undertake projects, programs, or portfolios to deliver value and achieve strategic objectives.
