Asset Critical Ranking (ACR) is a way for users to determine the criticality of an Asset by answering questions with numerical values as determined by site administrators.

ACR questions can be set up using the following steps:

Select Administration.
Select Settings.
Select Assets.
Select New Question.
Select OK.
Repeat steps 4 - 5 as necessary.
Select Save.

Once the ACR questions have been set up they can be used on Assets using the following steps:

Select Assets.
Select the appropriate Asset Class (Equipment, System, Location, or Repairable Spare).
Select Action.
Select Calculate ACR.
Input appropriate answers.
Select OK.

Note: The Calculate ACR Action's availability is determined by your Role setup. If the Action is unavailable you will need to contact your site administrator to adjust your Role setup.
