Maintenance Significance Curves
Graphical analysis to communicate the return on investment from maintenance practices, particularly in regards to the service life of assets.

The curves are often used in the development of maintenance optimization models and to anticipate the probability of failure (PoF) of an asset.

The higher the robustness of an asset the smaller the significance of the maintenance efforts.

The effects of maintenance, or lack thereof, will manifest itself in the following ways
