This topic provides an example of ASO analyses to explain how ASO analyses are created and used.
This ASO analysis example involves a water bottling facility. The water bottling facility is a unit, labeled the Water Bottling Unit. This unit contains two systems: Water Collection System and Bottling System. Each system contains equipment that work together to complete a single process.
The Water Collection System contains the following equipment:
The Bottling System contains the following equipment:
The unit, systems, and equipment and the process in which they are involved are illustrated in the following image.
An ASO analysis begins with an asset strategy, system strategy, or unit strategy. Our ASO analysis example includes the following strategies, where the indentation of the bullets indicates the structure of the strategies:
Note: For this example, each asset strategy has an active strategy and a proposed strategy that are different from one another.
The following image shows the records and links that are used to create the association between the Unit Strategy, one of its System Strategies, one of its Asset Strategies (Water Pump Strategy), and the Asset Strategy's Action and Risk records.
The following image illustrates existing records and links after the ASO Analysis is created. The colors in the image have the following meanings:
Asset Data
The Equipment record Water Pump contains the following values:

Active Scenario
Action Data
The following table shows the example data that is used in the Actions that are defined for the Water Pump Strategy and belong to the Active Scenario. Because the Active Scenario always reflects data that was mapped from ASM and these values cannot be changed, this table includes only the values that are specific to ASO and were not mapped from ASM.

Proposed Scenario
Action Data
The following table shows the example data that is used in the Actions that are defined for the Water Pump Strategy and belong to the Proposed Scenario. Because you can change the values that were originally mapped from ASM to a Proposed Scenario, this table includes the values that are specific to ASO and those that were mapped from ASM. In our example, however, we have not changed these values from their original ASM values. To distinguish between the two types of values, values that were mapped from ASM are colored gray in the table.
