About This Item
TS ISO 21506 is a vocabulary standard for the terms and definitions used in project, programme and portfolio management. Its role is not to prescribe a management method, but to establish a shared language so that organisations can use the same concepts consistently across teams, sectors and levels of complexity.
Why common terminology matters in management disciplines
Project, programme and portfolio management are related but distinct. A project is typically focused on delivering a defined outcome, a programme coordinates related initiatives, and a portfolio represents a broader set of work and investments aligned with organisational strategy. Vocabulary standards help keep these distinctions clear when documents, plans and decisions are shared across different stakeholders.
According to the scope of this document, it applies to any type of organisation, public or private, and to any project, programme or portfolio regardless of size, duration or complexity. As GENERAL TECHNICAL CONTEXT, a terminology standard with this kind of coverage supports consistent documentation, reporting, training and governance by reducing ambiguity in how management concepts are used.

- Brings terminology into one consistent reference for project, programme and portfolio management.
- Supports a common professional language across organisations and sectors.
