+======================
+Time in stage analysis
+======================
+
+The *Time In Stage Analysis* report provides information on how long applicants stay in each stage
+of the recruitment process. This is important, as every job position has specific :ref:`process
+details <recruitment/new_job_position/edit>` that state the length of time applicants should expect
+to wait between specific stages.
+
+Knowing how long applicants remain in each stage can help highlight possible bottlenecks. Analyzing
+this data allows the recruitment team to assess each stage, identify any issues, and pivot their
+strategies to move applicants through each stage, within the expected time interval.
+
+Time in stage analysis report
+=============================
+
+To access the report, navigate to :menuselection:`Recruitment app --> Reporting --> Time in Stage
+Analysis`. By default, the report displays data from all job positions, with the stages populating
+the x-axis, and the number of days populating the y-axis, in a :icon:`fa-line-chart`
+:guilabel:`(Line Chart)`.
+
+The default filter is :guilabel:`Last 365 Days Applicant`, showing information for the last 365
+days.
+
+Hover over a stage in the line chart to reveal a popover window listing all the job positions within
+it, and the average number of days each job position sits in each stage.
+
+For a more visually digestible view of the information in the :guilabel:`Time In Stage Analysis`
+report, click the :icon:`fa-bar-chart` :guilabel:`(Bar Chart)` icon in the upper-left corner. This
+displays all the information in a bar chart.
+
+In this view, it is easier to visualize the differences between the job positions, regarding how
+long applicants stay in each stage. From this view, recruiters can more easily determine which job
+positions have delays or bottlenecks at certain stages.

+
+Use case: comparing times by month
+----------------------------------
+
+With the :guilabel:`Time In Stage Analysis` report, it is possible to see if there are certain
+months where applicants take longer to be moved through the pipeline. To view this data, switch to
+the :icon:`oi-view-pivot` :guilabel:`(Pivot)` view in the upper-right corner.
+
+This presents the data in a detailed pivot table, with the rows representing the different job
+positions, and the columns representing the stages. The average :guilabel:`Days in Stage` populates
+the various boxes.
+
+.. note::
+   If a field is empty, it indicates no applicant has been in that stage. Instead, all applicants
+   moved from a previous stage without being placed in the stage with an empty field.
+

+   :alt: The pivot table view of the Time In Stage Analysis report.
+
+Click :icon:`fa-minus-square-o` :guilabel:`Total` above the job position rows to collapse the
+information. Next, click :icon:`fa-plus-square` :guilabel:`Total` again, revealing a drop-down menu.
+Click :guilabel:`Add Custom Group` :icon:`fa-caret-down` at the bottom of the list, revealing
+further grouping options. Click :guilabel:`Start Date` from the expanded list.
+
+After doing so, the data presented is grouped with the various months from the previous 365 days for
+the rows, leaving the :guilabel:`Days In Stage` as the columns.
+
+.. image:: time_in_stage/time-dates.png
+   :align: center
+   :alt: The pivot table showing the months averages for times in stage.
+
+In this example, :guilabel:`July 2024` had the longest time that applicants spent in each stage, on
+average. In addition, the :guilabel:`Contract Proposal` stage had the longest wait time in July,
+with an average of :guilabel:`31.62` days in that stage.
+
+While this report does not display the reasons applicants stayed in the various stages for these
+lengths of time, it can be helpful to know when delays occur.
