- The [hierarchy](/v410/docs/pei-hierarchy-overview) (FLOCs and Equipment) is inherited from IMS.
- The Turnaround (Planned Event) should already be in IMS. See [Reviewing Planned Events in Settings](/v410/docs/reviewing-planned-events-in-settings)
- Schedule Equipment for Turnaround by importing the Turnaround scope. IMS creates a Schedule for each Equipment, connecting Equipment with the Turnarounds. See [Scheduling Equipment for a TA](/v410/docs/scheduling-equipment-for-a-turnaround).
- Create an Equipment Condition History (ECH) for the Equipment that is Scheduled for Turnaround. See [Creating an ECH](/v410/docs/creating-an-equipment-condition-history-ech).
- Credit the Schedule in the ECH to generate the Checklists. See [Crediting the Schedule in the ECH](/v410/docs/crediting-the-schedule-in-the-ech-to-generate-the-checklists).
- Capture the findings in the ECH. Fill in the Checklists and add Observations with photos. You can also add a Narrative and annotated Drawings. See [Capturing findings in the ECH](/v410/docs/capturing-findings-in-the-condition-history).
- Generate a Discovery Work Request form, if needed. See [Generating a Discovery Work Request form](/v410/docs/generating-a-discovery-work-request-form).
- Create a CAIR when Discovery Work is approved. See [Creating a CAIR](/v410/docs/creating-a-cair).
- Close the ECH by Approving it. See [Approving the ECH](/v410/docs/approving-the-condition-history).
