# What is Tiering
|
|
|
|
Tiering is an important concept of data classification in OpenMetadata. Data Producers and Consumers can set business importance of data by setting Tiers. `Tier 1` is the most important data of an organization.
|
|
|
|
In OpenMetadata, Tiers are System Classification tags and can be accessed from **Govern > Classification > Tier**.

In case of tiering, it is easiest to start with the most important (Tier 1) and the least important (Tier 5) data. Once the **Tier 1** or most important data is identified, organizations can focus on improving the descriptions and data quality. The Data Insights in OpenMetadata helps identify the unused datasets as **Tier 5**. The Tier 5 datasets can be deleted periodically to declutter. Other tiers can be added as per your organizational needs. **Tags** can be added to further mark the data assets.

|
|
| **Tier 2** | Moderate | Some External & Mostly Internal Decisions | Some Regulatory | Highly used |
|
|
| **Tier 3** | Low | Internal Decisions | - | Highly used (Top N percentile) |
