The performance dashboard helps you manage labeling operations in your Labelbox projects by reporting on the throughput, efficiency, and quality of your labeling process. You can see analytics for the overall project and for individual labelers. Filters are available to help you focus on specific information and dimensions. The performance of your data labeling operation is broken down into four components, each with unique views to help you understand the overall performance:
  • Individual
  • TEQ (Throughput, Efficiency, and Quality)
  • Participation
  • Instruction Quiz (see Quiz)
You can use the filters at the top of the performance dashboard to analyze relevant subsets of data. When active, these filters apply to all metric views, including Throughput, Efficiency, and Quality. The following filters are available:

Throughput, efficiency, and quality (TEQ)

This section provides three separate views to help you understand the performance of your labeling operation: Throughput, Efficiency, and Quality.

Throughput view

The throughput view provides insight into the amount of labeling work being produced and helps you answer questions like:
  • How many assets were labeled in the last 30 days?
  • What is the review time and rework time for labeled assets?
  • What is the average amount of labeling work being produced?
These metrics are available for all members of the project and for individual members. The throughput view displays the following charts:

Forecast

The forecast feature shows your average daily throughput and completed work (data rows, labels, reviews, annotations) and uses that to forecast completion dates. To see this, enable the Forecast toggle.

Average daily throughput

The average daily throughput is calculated by dividing the total units completed in the selected date range by the number of calendar days in that range. Where:
  • Total units completed = sum of the relevant throughput metric over the selected period (e.g., total labels created, total reviews, etc)
  • Number of calendar days = inclusive of days between start and end date (e.g., Jan 1–Jan 7 → 7 days). This aligns the “average per day” with how the forecast projects completion over calendar time.
For example, if a project has 2,800 labels created over a 14-day window, the average daily throughput for labels would be 200 labels/day (2,800 labels / 14 days). Enable Forecast Toggle Note that metric units in this view can vary:
  • For Labels created / Reviews received / Annotations created, average daily throughput is in units like “labels/day”, “reviews/day”, “annotations/day”.
  • For time-based metrics, the forecast uses those as inputs, but the primary “average daily throughput” surfaced is for the count-based metrics (data rows/labels/reviews/annotations), per the spec and launch comms.

Efficiency view

The efficiency view helps you visualize the time spent per unit of work, per labeled asset, or per review. These metrics help answer questions such as:
  • What is the average amount of time spent labeling an asset?
  • How can I reduce the time spent per labeled asset?
Performance Tab Efficiency View Pn These metrics are available for individual project members and at the project level. The efficiency view includes these charts:
“Skipped” time is excluded from labeling time, and “abandoned” (unsaved) work is counted toward labeling time. You can use filters to include or exclude time spent on “deleted” labels.

Quality view

The quality view helps you understand the accuracy and consistency of the labeling work being produced. These metrics answer questions like:
  • What is the average quality of a labeled asset?
  • How can I ensure label quality is more consistent across the team?
These metrics are available for individual project members and for the project as a whole. The quality view includes the following charts, which will only display if the corresponding features (Benchmark and Consensus) are enabled for your project:

Individual member performance

Click Individual in the Performance dashboard to view individual metrics for each team member that has worked on the project. The performance metrics are separated by intent (labeling and reviewing) and are shown as distinct views in the table. Team members are listed individually in separate rows and will only appear if they have actively performed tasks during the selected period.

Labeling metrics

Here are the metrics displayed in the IndividualLabeling view.

Reviewing metrics

Here are the metrics displayed in the IndividualReviewing view.

Participation histogram

The Participation histogram is a chart in the Performance Dashboard that visualizes the distribution of labeler activity across a project.
Participation Histogram
Specifically, it shows:
  • How many labelers fall into different activity buckets (e.g., by number of tasks completed or labels created)
  • It helps admins see at a glance whether participation is concentrated among a few heavy contributors or spread evenly across the workforce
This is distinct from aggregate throughput charts — rather than showing total output over time, it shows the spread of engagement across individual contributors. It’s useful for identifying:
  • Labelers who haven’t participated at all
  • Labelers who are highly active vs. barely active
  • Overall workforce engagement health for a project

Timer details

To help you measure efficiency, the timer log tracks how much time is spent on each data row. The time is broken down into three categories: labeling, reviewing, and reworking.

How time is tracked in your project

A data row goes through many different states, which are tracked in the timer log.
Important notes
  • Inactivity Pause: If a user is inactive for more than five minutes, the timer will automatically pause. It will resume as soon as they become active again.
  • Consensus and Benchmarks: If your project uses consensus or benchmarks, the time recorded for a data row will be the total time spent across all labels created for that data row.

How importing labels impacts the timer

Importing labels affects labeling time. When you import:
  • Ground truth labels: No label time is recorded on the Data rows tab or the performance dashboard for that label. Label time is displayed as zero (0). When team members modify the label, time is recorded as review time.
  • Model-assisted learning (MAL) pre-labels: No label time is recorded on the Data rows tab or the performance dashboard for that label. Label time is displayed as zero (0). When team members open the data row in the editor and click Edit, the time spent before selecting Skip or Submit is recorded as labeling time.
