Trellis Score report
Definition
The Trellis Score report calculates and displays the Trellis Scores by individual developers. The trellis score can be further divided into the following categories:
- Quality: Quality is defined by two metrics: Percentage of rework and percentage of legacy rework.
- Impact: Impact is defined by two metrics: High-impact bugs worked on per month and high-impact stories worked on per month. Impact refers to the ticket's perceived significance or priority.
- Volume: Volume measures the quantity of code that the developer is working on.
- Speed: Speed measures the pace at which developers are writing and submitting code.
- Proficiency: Proficiency measures how many projects are currently being worked on. It is based on two metrics: Technical breadth and repo breadth.
- Leadership and Collaboration: Leadership and collaboration measures developer teamwork and contribution to peer reviews.
The factors and weight associated with the Trellis Score are essentially defined at the profile level. To learn more, go to Trellis Profile.

Trellis Scores are calculated from the factors mentioned above: Code Quality, Code Volume, Speed, Impact, Proficiency, and Collaboration. You can adjust the weight given to each factor, allowing for granular-level assessments based on individual profiles.
The report calculates the score for every Contributor and presents the overall Trellis score, along with a breakdown of the score for each factor. For more information, refer to the Trellis Calculation Guide.
Trellis Score by Collection
Definition
The Trellis Score by Collection report calculates and displays the Trellis Scores organized by Collection. This report provides a high-level view of the performance of different teams or groups within an organization.

Step 1: Add the widget
- Select Settings, then Add Widget.

Step 2: Configure the Filters for the widget
- Define the Time Interval for the data to be displayed in the widget. For example: Last Quarter. This means that the widget will calculate and display data for the Last Quarter.
- You can choose to display the scores of the immediate child Collections only, providing a more focused view of the performance of specific teams or groups.
Step 3: Save the widget
Complete the widget settings and select Next: Place Widget, place the widget on Insight and then select Save Layout.
Calculation
The factors and associated metrics used in the Trellis Score by Collection report are identical to the general Trellis Score calculation. The key difference is that the score for each Collection is calculated as the average Trellis score across all users in that Collection.
The formula for the Trellis Score by Collection is:
Trellis Score by Collection = (Sum of Trellis Scores of all the users in the Collection) / (Number of users in the Collection)
This allows you to quickly identify the top-performing Collections, as well as those that may need more attention or support.
