ISO 41011:2024

Overview

ISO 41011:2024 - Facility management - Vocabulary is the International Organization for Standardization’s updated glossary for facility management (FM). This second edition defines consistent terms and definitions used across the FM discipline to improve clarity in planning, delivery and governance of built‑environment services. It replaces ISO 41011:2017 and adds new term categories (notably technology and sustainability) and many contemporary entries such as workspace, constructed asset, service life, smart building, greenhouse gas and well‑being.

Key topics and technical scope

ISO 41011:2024 organizes terminology into focused categories that reflect practical FM domains:

• Terms related to facility management: facility management, facility service, workplace, workspace, service level, SLA.
• Assets and built environment: asset, constructed asset, built environment, facility, infrastructure, service life.
• People and governance: stakeholder, demand organization, top management, responsibility assignment matrix, communication plan.
• Sourcing and contracts: agreement, contract, co‑sourcing, demobilization, procurement plan.
• Processes and measurement: facility process, output vs outcome, post‑occupancy evaluation, measurement and performance terms.
• Finance and whole‑life costing: acquisition cost, maintenance cost, whole‑life cost, cost‑benefit analysis.
• Technology and sustainability: computer aided facility management, smart building, life cycle assessment, greenhouse gas, sustainable development, well‑being.

The standard draws on and harmonizes terminology from related documents (for example ISO 55000, ISO 9000, ISO/TR 15686‑11 and ISO 6707‑4).

Practical applications and users

ISO 41011:2024 is a foundational reference for anyone needing a common FM vocabulary to reduce ambiguity and improve coordination:

• Facility managers and FM organizations – to standardize internal documentation, SLAs and service definitions.
• Asset and real estate managers – for consistent terms around asset life, infrastructure and whole‑life costing.
• Procurement and contract teams – to clarify agreements, performance specifications and demobilization.
• Designers, architects and engineers – to align on workspace, constructed asset and post‑occupancy evaluation terminology.
• Sustainability and building‑technology teams – when addressing greenhouse gas, life‑cycle assessment and smart building concepts.
• Consultants and auditors – for assessments, stakeholder impact analysis and harmonized reporting.

Using ISO 41011:2024 improves communication between stakeholders, supports clearer contracts (SLAs), enables more consistent measurement and reporting, and helps integrate sustainability and digital building concepts into FM practice.
