What does the term 'asset portfolio' refer to in ISO 55000?

• A. Assets within the scope of the asset management system
• B. All physical assets regardless of scope
• C. Only assets with high value
• D. Only assets owned by the entity

Answer: (A)

In ISO 55000, the asset portfolio is the set of assets that fall within the scope of the asset management system—the assets the organization has chosen to manage to realize value and achieve its objectives. This means the portfolio is defined by what you include in the asset management scope, not by ownership, location, or value alone. Assets outside that scope aren’t part of the portfolio. Defining the portfolio helps focus planning, decision-making, and resource allocation on the assets that the asset management processes actively manage, ensuring consistent application of risk, performance, and lifecycle activities across those assets.
