# RCM Queries - Background

This article explains when and why to use a Query in RCM, as part of the broader [IMS Queries](/v414/docs/ims-queries) functionality. For general tips on working with queries day-to-day, see [Working with Queries](/v414/docs/working-with-queries). For worked examples, see the other articles in this category.

## When to Use a Query in RCM?

### Data That's Hard to Reach Directly in IMS

For example:

- PLEs created, assigned and used.
- Functions and Functional Failures on Systems.
- Criticalities, Residual Risks, and Approved analyses.

### Repetitive, Consistent, Quick Data Extraction

For example:

- Incomplete data or missing elements.
- Progress tracking of RCM analyses or RSL application.
- Scope of work done or remaining.
- RCM data quality checks.

### Data Source for Dashboards

To check specific data daily when users log on. See also: [Dashboard Overview](/v414/docs/dashboard-introduction).

> Depending on the methodology (PEI, RCM, SIS, PLSS), other query aspects may be involved. This article addresses aspects relevant specifically to RCM.

Next, you will find some typical examples of RCM Queries. This video shows how to create a query, step-by-step:
