# How do I change the risk calculation methodology?

Dronedesk supports different risk calculation methods. This video walks you through how to switch to a model that best suits your operational standards.

When it comes to **risk assessment scoring**, Dronedesk gives you full control over how scores are calculated and displayed.

To configure these options:

1.  Go to the **top-right menu**, select **Settings**, then click **Risk Assessments**
    
2.  Click the **gear icon** to access **Risk Scoring Configuration**
    

In this section, you’ll find several settings:

-   **Matrix colours**  
    Choose between a **standard 3-colour matrix** or a **broader colour range** to better visualise risk severity.
    
-   **Risk score display**  
    You can choose to show the **numerical score within each cell** of the matrix and select a colour for how that score is displayed.
    
-   **Score components**  
    You can also enable the display of the **score components** below each square, such as "Probability: 3, Severity: 5".
    
-   **Per-risk score calculation**  
    Choose between:
    
    -   **Additive**: where Probability 2 + Severity 3 = Total Score 5
        
    -   **Multiplicative**: where Probability 2 × Severity 3 = Total Score 6
        
-   **Overall risk score calculation**  
    Decide how the **total score** for the entire risk assessment is calculated:
    
    -   **Summation**: adds all individual risk scores (e.g. 2 + 6 + 6 + 10 + 10 + 20 = 54)
        
    -   **Average**: calculates the mean score (in this case, 9)
        
    -   **Maximum**: uses the highest individual risk score (e.g. 20)
        

These options provide the flexibility needed to align with most risk management approaches and internal safety protocols.
