Whole-life cost and the operating consequence

Has the cost of owning this asset been estimated by, or at least shown to, the people who will have to pay it?

What goes wrong without it

Capital and operating budgets usually sit in different organisations with different reporting lines, and the design decisions that fix operating cost are taken entirely inside the first. The operator inherits a cost they did not forecast and cannot now avoid. This is the single largest transfer of unpriced obligation in the lifecycle and it happens without anyone breaching a control.

What to examine

  • Ask whether an operating cost estimate exists at all. Frequently it does not.
  • Identify who produced it. An operating estimate produced by the delivery team, with no operator involvement, is a delivery assumption rather than a forecast.
  • Check whether any design decision has been reversed or altered on operating cost grounds. If none ever has, whole-life costing is presentational.
  • Confirm the financial and technical views of the asset use the same asset breakdown, since alignment between them is the subject of its own standard.

Required by

  • ISO 55001:2024, Clause 6.2.1, requiring a strategic asset management plan documenting the role of the asset management system in achieving the asset management objectives.
  • ISO 55001:2024, Clause 8.1, which in the second edition makes explicit that operational planning and control includes life cycle management.
  • ISO/TS 55010, guidance on the alignment of the financial and non-financial functions of the organisation in asset management.
  • ISO 55000:2024, which states alignment among its principles: asset management aligns financial, technical and operational decisions with the organizational objectives.
