# Cohort analysis
The **Cohort analysis** report compares engineering metrics side-by-side across user-defined segments of your organization. Define up to three cohorts based on team attributes, then see how each group performs relative to a baseline.

This report helps teams:

- **Compare performance across segments** — Measure how different teams, roles, locations, or any other attribute-based group stack up on key engineering metrics.
- **Evaluate the impact of changes** — See whether a new process, tool, or organizational change is moving the needle for a specific group compared to the rest of the organization.
- **Identify areas for investment** — Spot which segments are underperforming on cycle time, throughput, or developer experience so you can target support where it's needed most.
- **Benchmark against industry** — Overlay industry P50/P75/P90 benchmarks on any metric to see how each cohort compares externally.

## Setting up cohorts

The report starts with two groups: a **Baseline** and **Cohort 1**. You can add up to two more (three total in addition to the baseline) using the **Add cohort** button.

- **Baseline** — The reference group that all other cohorts are compared against. By default this is "All attributes across all users," but you can customize it to any attribute set.
- **Cohort 1–3** — Comparison groups. Select attributes to define each cohort's membership.

### Defining a cohort with attributes

Each cohort is defined by selecting one or more attributes from your organization's attribute groups (e.g., Team, Location, Role). Attributes support both inclusion and exclusion:

- _is / is any of_ — Include users matching the selected attribute values.
- _is not / is not any of_ — Exclude users matching the selected attribute values.

You can combine multiple attribute groups within a single cohort for more targeted comparisons (e.g., "Team is Engineering **and** Location is not Remote").

## Metrics

Each metric is displayed as a tile in a responsive grid. Use the tiles dropdown (grid icon) to choose which metrics to display. Your tile selection is saved across sessions.
