+******
+Design
+******
+
+The *Production Routing Module* introduces or extends the following concepts.
+
+.. _model-production.routing:
+
+Routing
+=======
+
+A *Routing* specifies the operational steps involved in a `Production
+<production:model-production>` process and the order in which in they occur.
+Routings can be linked to multiple `Bill of Materials
+<production:model-production.bom>`.
+
+.. seealso::
+
+   The Routings can be found using the main menu item:
+
+      |Productions --> Configuration --> Routings|__
+
+      .. |Productions --> Configuration --> Routings| replace:: :menuselection:`Productions --> Configuration --> Routings`
+      __ https://demo.tryton.org/model/production.routing
+
+.. _model-production.routing.operation:
+
+Operation
+=========
+
+An *Operation* is a general production activity.
+
+.. seealso::
+
+   The *Operations* can be found using the main menu item:
+
+      |Productions --> Configuration --> Routings --> Operations|__
+
+      .. |Productions --> Configuration --> Routings --> Operations| replace:: :menuselection:`Productions --> Configuration --> Routings --> Operations`
+      __ https://demo.tryton.org/model/production.routing
+
+.. _concept-product:
+
+Product
+=======
+
+When the *Production Routing Module* is activated, products gain some extra
+properties.
+A `Routing <model-production.routing>` can be specified for each `BOMs
+<production:model-production.bom>` listed.
+A production lead times can also be defined per `Routing
+<model-production.routing>`.
+
+.. seealso::
+
+   The `Product <production:concept-product>` concept is extended from the
+   :doc:`Production Module <production:index>`.
+
+.. _model-production:
+
+Production
+==========
+
+When the *Production Routing Module* is activated, productions gain some extra
+properties such as the `Routing <model-production.routing>` which is used to
+adapt the lead time.
+
+.. seealso::
+
+   The `Production <production:model-production>` concept is introduced by the
+   :doc:`Production Module <production:index>`.

+#########################
 Production Routing Module
 #########################
 
-The production routing module defines the routings for production: Routing,
-Step and Operation.
+The *Production Routing Module* provides the fundamental concept for
+managing operations on productions.
 
-Routing
-*******
+.. toctree::
+   :maxdepth: 2
 
-Routings are a list of steps to follow with one of the BOMs to produce a
-product.
-
-Step
-****
-
-Steps define the operation to perform at a specific point of the routing.
-
-Operation
-*********
-
-An operation is a generic action.
