# What is key driver analysis?
Key Driver Analysis uses a statistical technique known as [Pearson correlation](/knowledge-base/step-5-analyze-interpret-and-report/compass-reports/reporting-faq/what-is-pearson-correlation.md) to identify patterns in the responses of employees. By using Pearson correlation, it is possible to identify which questions have the strongest and most meaningful association with your employee engagement score.
When you prioritize your intervention efforts based on the results of statistical analysis, the results are far superior to simply basing intervention efforts on the lowest scoring items in a survey. Typically the lowest scoring items (like compensation) have a very weak connection with employee engagement, and thus even large investments to improve these low scoring items do not result in large improvements in engagement.
### How does TalentMap determine key drivers for my organization?
TalentMap has a scientific method for identifying key drivers of engagement for your specific organization. Our methodology takes into consideration the size of your organization, Pearson correlation, comparison data and overall performance scores.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.talentmap.com/knowledge-base/step-5-analyze-interpret-and-report/compass-reports/reporting-faq/what-is-key-driver-analysis.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
