+Work order dependencies
+=======================
+
+.. |BOM| replace:: :abbr:`BoM (Bill of Materials)`
+
+When manufacturing certain products, specific operations may need to be completed before others can
+begin. In order to ensure operations are carried out in the correct order, Odoo *Manufacturing*
+features a *work order dependencies* setting. Enabling this setting allows for operations on a Bill
+of Materials (BoM) to be *blocked* by other operations that should occur first.
+
+Configuration
+=============
+
+The *work order dependencies* setting is not enabled by default. To enable it, begin by navigating
+to :menuselection:`Manufacturing --> Configuration --> Settings`. Then, enable the :guilabel:`Work
+Orders` setting, if it is not already active.
+
+After enabling the :guilabel:`Work Orders` setting, the :guilabel:`Work Order Dependencies` setting
+appears below it. Enable :guilabel:`Work Order Dependencies`, then click :guilabel:`Save` to confirm
+the changes.
+
+Add dependencies to BoM
+=======================
+
+Work order dependencies are configured on a product's |BOM|. To do so, navigate to
+:menuselection:`Manufacturing --> Products --> Bills of Materials`, then select a |BOM|, or create a
+new one by clicking :guilabel:`New`.
+
+.. admonition:: Learn more
+
+   For a complete guide on how to properly configure a new |BOM|, see the documentation on
+   :ref:`creating a bill of materials <manufacturing/management/bill-configuration>`.
+
+On the |BOM|, click on the :guilabel:`Miscellaneous` tab, then enable the :guilabel:`Operation
+Dependencies` checkbox. This makes a new :guilabel:`Blocked By` option available in the settings of
+the :guilabel:`Operations` tab.
+
+.. image:: work_order_dependencies/operation-dependencies.png

+
+Next, click on the :guilabel:`Operations` tab. On the top-right of the tab, click on the tab's
+:guilabel:`settings` button, then enable the :guilabel:`Blocked By` checkbox. This makes a
+:guilabel:`Blocked By` field appear for each operation on the :guilabel:`Operations` tab.
+
+.. image:: work_order_dependencies/operations-settings.png
+   :align: center
+   :alt: The settings for the Operations tab on a BoM.
+
+In the line of the operation that should be blocked by another operation, click the
+:guilabel:`Blocked By` field, and an :guilabel:`Open: Operations` pop-up window appears. In the
+:guilabel:`Blocked By` drop-down field on the pop-up window, select the blocking operation that must
+be completed *before* the operation that is blocked.
+
+.. image:: work_order_dependencies/blocked-by.png

+
+Finally, save the |BOM| by clicking :guilabel:`Save`.
+
+Plan work orders using dependencies
+===================================
+
+Once work order dependencies have been configured on a |BOM|, Odoo *Manufacturing* is able to plan
+when work orders are scheduled, based on their dependencies. To plan the work orders for a
+manufacturing order, begin by navigating to :menuselection:`Manufacturing --> Operations -->
+Manufacturing Orders`.
+
+Next, select a manufacturing order for a product with work order dependencies set on its |BOM|, or
+create a new manufacturing order by clicking :guilabel:`New`. If a new manufacturing order is
+created, select a |BOM| configured with work order dependencies from the :guilabel:`Bill of
+Material` drop-down field, then click :guilabel:`Confirm`.
+
+After confirming the manufacturing order, select the :guilabel:`Work Orders` tab to view the work
+orders required to complete it. Any work orders that are *not* blocked by a different work order
+display a `Ready` tag in the :guilabel:`Status` section.
+
+Work orders that are blocked by one or more work orders display a `Waiting for another WO` tag
+instead. Once the blocking work order(s) are completed, the tag updates to `Ready`.
+
+.. image:: work_order_dependencies/work-order-status.png
+   :align: center
+   :alt: The status tags for work orders on a manufacturing order.
+
+To schedule the manufacturing order's work orders, click the :guilabel:`Plan` button at the top of
+the page. After doing so, the :guilabel:`Scheduled Start Date` field for each work order on the
+:guilabel:`Work Orders` tab auto-fills with the scheduled start date and time. A blocked work order
+is scheduled at the end of the time period specified in the :guilabel:`Expected Duration` field of
+the work order that precedes it.
+
+.. image:: work_order_dependencies/scheduled-start-date.png
+   :align: center
+   :alt: The Scheduled Start Date field for work orders on a manufacturing order.
+
+.. example::
+   A manufacturing order is created for Product A. The manufacturing order has two operations: Cut
+   and Assemble. Each operation has an expected duration of 60 minutes, and the Assemble operation
+   is blocked by the Cut operation.
+
+   The :guilabel:`Plan` button for the manufacturing order is clicked at 1:30 pm, and the Cut
+   operation is scheduled to begin immediately. Since the Cut operation has an expected duration of
+   60 minutes, the Assemble operation is scheduled to begin at 2:30 pm.
+
+Planning by workcenter
+----------------------
+
+To see a visual representation of how work orders are planned, navigate to the :guilabel:`Work
+Orders Planning` page by going to :menuselection:`Manufacturing --> Planning --> Planning by
+Workcenter`. This page shows a timeline of all the work orders scheduled for each operation.
+
+If one work order is blocked by the completion of another, the work order that is blocked is shown
+as scheduled to start after the work order blocking it. In addition, an arrow connects the two work
+orders, leading from the blocking operation to the blocked operation.
