PILAR translates the benefits of backup equipment up to the essential assets.

Evaluated values are shown on green background.

Aggregated values are calculated for

• essential assets, either information or services
• service access points ([null.sap])

In order to calculate it,

• PILAR takes into account the worst (longest) replacement time for the assets below
• unless OR nodes, that record the best (shortest) replacement time of its branches

and PILAR prints the maturity range of the assets below.

PILAR requires replacement times for all the assets involved; except for OR nodes, where some values may be unevaluated, and are ignored.

In order to simplify data entry, PILAR may accept that some assets are not evaluated

• essential assets
• OR nodes
• service access points ([null.sap])

This screen permits to measure the satisfaction of RTO objectives for services.
