## Overview
2021-02-10 18:09:02 +00:00
Code Review Analytics is available to users with Reporter access and above, and displays a table of open merge requests that have at least one non-author comment. The review time is measured from the time the first non-author comment was submitted.
2020-01-22 00:08:47 +00:00
2020-09-15 18:09:43 +00:00
To access Code Review Analytics, from your project's menu, go to **Project Analytics > Code Review** .
You can filter the list of merge requests by milestone and label.

2020-09-15 18:09:43 +00:00
The table is sorted by:
- **Review time**: Helping you to quickly find the longest-running reviews which may need intervention
or to be broken down into smaller parts.
- Other columns: Display the author, approvers, comment count, and line change (-/+) counts.

2020-09-15 18:09:43 +00:00
and others who want to understand broad code review dynamics, and identify patterns to explain them.
2020-01-18 00:09:18 +00:00
2020-09-15 18:09:43 +00:00
You can use Code Review Analytics to:
2020-01-21 00:08:46 +00:00
2020-09-15 18:09:43 +00:00
- Expose your team's unique challenges with code review.
- Identify improvements that might substantially accelerate your development cycle.
2020-01-21 00:08:46 +00:00
- Your team agrees that code review is moving too slow.
2020-02-07 21:08:39 +00:00
- The [Value Stream Analytics feature ](value_stream_analytics.md ) shows that reviews are your team's most time-consuming step.
2020-09-15 18:09:43 +00:00
- Analyze the patterns and trends of different types of work that are moving slow.
2020-01-21 00:08:46 +00:00
2020-09-15 18:09:43 +00:00
For example:
2020-01-21 00:08:46 +00:00
- Lots of comments or commits? Maybe the code is too complex.
- A particular author is involved? Maybe more training is required.
- Few comments and approvers? Maybe your team is understaffed.
