+Manage work orders using work centers
+=====================================
+
+Odoo Manufacturing allows for work orders to be carried out at specific work centers. When a
+manufacturing order is created for a product, any work orders listed in the :guilabel:`Operations`
+tab of the product bill of materials (BoM) will be automatically created as well and assigned to the
+specified work center. Work orders can be managed in the :guilabel:`Manufacturing` module by
+selecting :menuselection:`Operations --> Work Orders`.
+
+In order to use work centers, the :guilabel:`Work Orders` feature must first be enabled. To do so,
+go to the :guilabel:`Manufacturing` module, select :menuselection:`Configuration --> Settings`, and
+activate the checkbox next to :guilabel:`Work Orders`. Work centers can then be created and managed
+by selecting :menuselection:`Configuration --> Work Centers`.
+
+Create a work center
+====================
+
+Within the :guilabel:`Manufacturing` module, select :menuselection:`Configuration --> Work Centers
+--> Create`. The work center form can then be filled out as follows:
+
+- :guilabel:`Work Center Name`: give the work center a concise name that describes the type of
+  operations it will be used for
+- :guilabel:`Alternative Workcenters`: specify an alternative work center for operations to be
+  carried out at if the main work center is not available
+- :guilabel:`Code`: assign the work center a reference code
+- :guilabel:`Working Hours`: define the number of hours that the work center can be in use each week
+- :guilabel:`Company`: select the company that the work center belongs to

+
+Set standards for work center productivity
+------------------------------------------
+
+The :guilabel:`General Information` tab on the work center form allows for productivity goals to be
+assigned to a work center:
+
+- :guilabel:`Time Efficiency`: used to calculate the expected duration of a work order at the work
+  center; for example, if a work order normally takes one hour and the efficiency is set to 200%,
+  the work order will take 30 minutes
+- :guilabel:`Capacity`: the number of operations that can be performed at the work center
+  simultaneously
+- :guilabel:`OEE Target`: the target for efficiency at the work center
+- :guilabel:`Time before prod.`: setup time required before work can commence
+- :guilabel:`Time after prod.`: breakdown or cleanup time required after work is finished
+- :guilabel:`Cost per hour`: the cost of operating the work center for one hour
+- :guilabel:`Analytic Account`: the account where the cost of the work center should be recorded

+
+Assign equipment to a work center
+---------------------------------
+
+Using the :guilabel:`Equipment` tab, it is possible for specific pieces of equipment to be assigned
+to a work center. The following information will be displayed for each piece of equipment added:
+
+- :guilabel:`Equipment Name`: the name of the piece of equipment
+- :guilabel:`Technician`: the technician responsible for servicing the equipment
+- :guilabel:`Equipment Category`: the category the equipment belongs to
+- :guilabel:`MTBF`: mean time between failures; the average time that the piece of equipment will
+  operate before failing
+- :guilabel:`MTTR`: mean time to recovery; the average time it takes for the equipment to become
+  fully operational again
+- :guilabel:`Est. Next Failure`: an estimate of when the next equipment failure will occur
+
+.. image:: using_work_centers/work-center-equipment.png
+   :align: center
+   :alt: The equipment tab of the work center form.
+
+.. note::
+    :guilabel:`MTBF`, :guilabel:`MTTR`, and :guilabel:`Est. Next Failure` are all calculated
+    automatically based on past failure data, if any exists.
+
+Integrate IoT devices
+---------------------
+
+The :guilabel:`IoT Triggers` tab enables the integration of :abbr:`IoT (Internet of Things)` devices
+with a work center:
+
+- :guilabel:`Device`: specifies the IoT device to be triggered
+- :guilabel:`Key`: the security key for the device
+- :guilabel:`Action`: the IoT device action triggered
+

+
+Use case: configure an alternative work center
+==============================================
+
+When a work center is at capacity, it cannot accept any new work orders. Instead of waiting for the
+work center to become available, it is possible to specify an alternative work center where surplus
+work orders should be carried out.
+
+Begin by creating a new work center. Configure the :guilabel:`Equipment` tab so that it has all of
+the same equipment as the main work center. This will ensure that the same tasks can be carried out
+at both work centers. Navigate to the main work center and include the new work center in the
+:guilabel:`Alternative Workcenters` selection field.
+
+Now, create a new manufacturing order that uses the main work center for one of its operations. The
+main work center will automatically be selected for the operation in the :guilabel:`Work Orders`
+tab. After confirming the manufacturing order, click the :guilabel:`Plan` button that appears at the
+top left of the form.
+
+.. image:: using_work_centers/manufacturing-order-plan-button.png
+   :align: center
+   :alt: Click the plan button to automatically select an available work center.
+
+If the main work center is at capacity, the work center selected for the operation will be
+automatically changed to the alternative work center.
+
+.. image:: using_work_centers/automatic-work-center-selection.png
+   :align: center
+   :alt: The alternative work center is automatically selected.
+
+Monitor work center performance
+===============================
+
+Performance for an individual work center can be viewed by selecting
+:menuselection:`Configuration --> Work Centers`, and clicking on a work center. A variety of metrics
+showing work center performance can be viewed at the top right of the form:
+
+- :guilabel:`OEE`: overall effective efficiency, the percentage of time that the work center has
+  been fully productive
+- :guilabel:`Lost`: the amount of time lost due to work stoppages
+- :guilabel:`Load`: the amount of time it will take to complete the current workload
+- :guilabel:`Performance`: the real duration of work time, shown as a percentage of the expected
+  duration
