# Schedules Overview

**This online manual explains the Schedules in IMS:**

- The different [types of Schedules](/v414/docs/schedule-types) (Default, Inspection, Corrosion, CAIR, and RBI Re-Assessment).
- The [Schedule lifecycle](/v414/docs/schedule-lifecycle) and how it fits into the [IMS PEI workflow](/v414/docs/pei-hierarchy-overview).
- The [Next Inspection Date horserace](/v414/docs/next-inspection-date-nid-horserace).
- How to interpret and use the [Schedules Main Screen (list)](/v414/docs/schedule-main-screen).
- How to define Schedules (e.g. adding Scope and Plan codes).
- How to [create Schedules](/v414/docs/creating-schedules-inspection-cair-and-rbi-re-assessment), [Approve, extend, edit](/v414/docs/approving-editing-and-extending-schedules), [link to an event](/v414/docs/tying-schedules-to-upcoming-events), and [mark for WOP](/v414/docs/waiting-on-paperwork).

Note: For more information on how to execute and credit the PEI Schedules see [Step 13 (Execute, Analyze and Document) of the Degradation Management workflow](/v414/docs/step-13-barrier-verification-execute-analyze-document).

Organizing an Inspection (or other work) involves creating a plan that outlines which tasks need to be accomplished and when. This plan is outlined in a Schedule. It can be used for upcoming Planned Events, like Turnarounds, next Opportunities, Campaigns, Pitstop, for ongoing inspections of Equipment, for repairs, or for maintenance. Creating a Schedule allows you to determine the scope of the inspection (or other work), that is, which Equipment you need to work one, the [Next Inspection Date - NID](/v414/docs/next-inspection-date-nid-horserace), i.e. when you need to do the work, and how.

Schedule activities can be things such as: Perform an external visual inspection; Take Wall Thickness (WT) readings; Do a Repair; etc. As an example, the Planner / Inspector checks which Schedules are due (having a [NID](/v414/docs/next-inspection-date-nid-horserace) close to Today), then performs the inspection according to the Scope, captures the inspection results, and credit the Schedule(s) in the [Equipment Condition History (ECH)](/v414/docs/echoverview). In case of [recurring Schedule(s)](/v414/docs/schedule-lifecycle), a new Schedule will automatically be created with a new due date (see [Schedule Lifecycle](/v414/docs/schedule-lifecycle)).

In [PEI Hierarchy - Overview](/v414/docs/pei-hierarchy-overview) you can see a visual depiction of the PEI Workflow. It illustrates how the flow between the different objects in IMS occur. Take note of the flow to and from the different [Schedule types](/v414/docs/schedule-types).
