The need to balance these factors in order to satisfy stakeholders may result in suboptimal maintainability and supportability.


During the different stages and substages communication between the project owners, the operational organization and the engineering organization is essential for establishment of requirements to meet stakeholder needs. The maintenance policy is the basis for maintenance engineering in the life cycle and shall be consistent with the overall organization policy and objectives.

This insights, the Asset Management BowTie, can be added toward the Asset Management paradigm with the (Digital) Line of Sit. To add the BowTie principle, the body of thoughts of the EN-17485 can be incorporated in the Asset Management paradigm with the mentioned standards. Result is a deepened figure 1 of the ISO5500 completed with the Line(s) of Sights, the levels of information, Business, Risk Assessment and Asset & Maintenance going to decision making  in balancing Costs, Risks and Performance. The Asset Management BowTie show how standards can be uses as a reference framework.
