Overview
ISO 21508:2026 – Project, Programme and Portfolio Management - Earned Value Management is an international standard published by the International Organization for Standardization (ISO). This document provides comprehensive guidance on the use and implementation of Earned Value Management (EVM) across a wide range of organizations, regardless of size, sector, or project complexity. EVM is a proven methodology for objectively tracking project performance, integrating cost, schedule, and scope metrics to enhance decision-making in project, programme, and portfolio management.
This standard is designed to benefit executive managers, project sponsors, decision-makers, project management professionals, project management offices (PMOs), and individuals involved in performance management or developing organizational standards. It is structured to be adaptable for various types of projects and can be tailored to specific organizational needs.
Key Topics
