# MiRO Hierarchy

The IMS Hierarchy is set up to implement the Degradation Management work process. In general, IMS PEI is about identifying when and what Equipment to inspect and to have an audit trail of the results of these inspections. In IMS, the “when” is defined in an Equipment Inspection Schedule event. The results of the inspection are captured in the Equipment Condition History (ECH). The user checks which Schedules are due (having a Scheduled date close to Today), then performs the inspection, captures the inspection results and credit the Schedule(s) in the ECH. In case of recurring Schedule(s), a new Schedule will automatically be created with a new due date.

The figures below show the important objects and illustrates how the flow between the different objects occur.

In general the hierarchy is aligned with the PEI Hierarchy with the main difference that S-RBI (still in development) is replace with M-RBI and that the standard IMS Corrosion calculations have been replace with [M-IDAP](/v414/docs/m-idap-on-circuits).

In addition Planned Events can also be interface with the DIMATE-PACS to import data into Measurement Sets (MSETs) and Dynamic Forms in the ECH.

The objects that are interfaced (Equipment, CAIR Schedule, ECH, MSET) with, e.g., SAP or DIMATE, are indicated with an interface symbol.
