Start by looking at the root causes with the highest-ranking
When an observation (deviation in the plant process) is detected, the Control Room Assistant user interface will change into one single display showing all the findings.

Our recommendation when an upset has occurred:
Step.1 Look at the top-ranked root causes on the left hand of the screen
Step 2. Click on the root-cause you want to evaluate and you will see which observations support them (fingerprint). On the right side you will see the consequences they may lead to (to get a sense of how much time you have before you need to take action)
When you have selected the most likely root cause of the upset:
Step 3. If you are not sure yet, as there can still be several root causes, additional evidence (for or against) can be obtained by selecting a manual Verify proposal, asked under "Verify" (to double-check that the information in the control room is correct)
Step 4. When you are sure (have decided on the root-cause) take a quick look at the "correct" suggestion to see if you can deal with the issue or if somebody else needs to fix the root cause (the core of the problem). For example, establishing a maintenance order, etc..
If somebody else needs to fix the root cause of the problem. As a Control Room Operator, you often don`t have time to wait for maintenance or another dedicated team to fix the problem. They need to quickly take action to prevent escalation of the problem.
Step 5. Execute actions suggested under "Prevent" in the control system (as the CRA is giving help for awareness and suggestion what to do only).
When the situation has been handled, we recommend you sending more information to the dedicated team to help them learn from the root cause of the upset.
Step 6. Give yourself a high-five. You could not have handled the upset better.
