# How to add custom Phases and Subphases on Project Schedule Modal?

Custom phases and subphases allow you to tailor the project management process to the specific needs of your project

Standard Phases remain consistent across the entire team, ensuring uniformity in project structure. In contrast, Custom Phases are specific to individual Projects, providing flexibility and customization to meet the unique requirements of each project.

1.  To create a Custom Phase for this Project, click **+Add** on the top, then select **Add Phase**.

    To add a Custom Subphase, click the three-dot on the Phase and select **Add Subphase**.

2.  Click **Add Custom Phase** to proceed. Clicking the **Manage Standard Phases** button will open [Org Settings > Standards > Phases](https://support.mosaicapp.com/en/articles/302-organization-settings-standard-phases.md) in a new tab, where a standard Phase can be created and used across all projects.

3.  Enter the Phase title, Phase reference number (optional) and select the Phase tracking setting. The parent of this custom Phase can also be changed to an existing Phase, making it a Subphase. Click **Create** to finalize.
    
    > **Warning:** If a matching archived **Phase** exists, adding a new **Phase** to a **Project** with the same name and reference number will automatically unarchive the existing one.
