In ISO 55000, what does the asset portfolio refer to?

• A. Assets within the scope of the asset management system
• B. All assets owned by the organization
• C. The list of all projects
• D. The set of high-value assets

Answer: (A)

In ISO 55000, the asset portfolio represents the assets that fall within the scope of the asset management system—the assets the organization has decided to manage and optimize under that system. This boundary defines what is included in planning, decision-making, and performance improvement, covering the assets across their life cycles as appropriate to the system’s scope. It isn’t simply all assets the organization owns, because some assets may lie outside the defined management boundary or be governed by other arrangements. It isn’t the list of all projects, which belongs to project or program portfolio management rather than asset management. And it isn’t limited to high-value assets; it includes all assets within the defined scope.
