+
+Demand Driven Material Requirements Planning is a formal multi-echelon
+planning and execution method developed by Ms. Carol Ptak and Mr. Chad Smith.
+
+DDMRP combines blended aspects of Material Requirements Planning (MRP),
+Distribution Requirements Planning (DRP) with the pull and visibility
+emphases found in Lean and the Theory of Constraints and the variability
+reduction emphasis of Six Sigma.
+
+This method has five sequential components:
+
+#. *Strategic Inventory Positioning*. Answers the question "Given our system
+   and environment, where should we place inventory to have the best
+   protection?" and determines where should decoupling points of inventory be
+   placed.
+
+#. *Buffer Profiles and Levels*. Determine the amount of protection at those
+   decoupling points.
+
+#. *Dynamic Adjustments*. Allow the company to adapt buffers to group and
+   individual part trait changes over time through the use of several types
+   of adjustments.
+
+#. *Demand Driven Planning*. Allow to launch purchase orders (POs),
+   manufacturing orders (MOs) and Transfer Orders (TOs) based on the priority
+   dictated by the buffers.
+
+#. *Visible and Collaborative Execution*. These POs, MOs and TOs have to be
+   effectively managed to synchronize with the changes that often occur within
+   the "execution horizon."
+
+These five components work together to greatly dampen, if not eliminate,
+the nervousness of traditional MRP systems and the bullwhip effect in
+complex and challenging environments.
+
+This approach provides real information about those parts that are
+truly at risk of negatively impacting the planned availability of inventory.
+
+DDMRP sorts the significant few items that require attention from
+the many parts that are being managed. Under the DDMRP approach,
+fewer planners can make better decisions more quickly. That means companies
+will be better able to leverage their working and human capital.
+
+Demand Driven Material Requirements Planning is quickly being adopted
+by a wide variety of leading companies across the world.
+
+Some of the benefits reported by the DDMRP method include:
+
+* High fill rate performance
+* Lead time reductions
+* Inventory reductions, while improving customer service
+* Eliminate costs related to expedite
+* Planners see priorities instead of constantly fighting the conflicting
+  messages of MRP
+
+It is highly recommended to read the book 'Demand Driven Material
+Requirements Planning (DDMRP)' by Carol Ptak and Chad Smith.

+
+Installation
+============
+
+We strongly recommend to modify the configuration of the reservation method
+to manual in the outgoing operation types (so deliveries
+related to Sales Orders aren't automatically reserved) and to avoid to
+reserve stock for specific moves, buffers are in fact a reservation of stock.
+However, while **reservation is discouraged**, it is still available to be
+used, in case of reserved stock be aware that the buffer will be blind to this
+transfers and stock and you are bypassing the DDMRP reordering flow.
+
+Configuration
+=============
+
+Scheduled actions
+~~~~~~~~~~~~~~~~~
+
+* Go to *Settings > Technical*.
+* 'DDMRP Buffer ADU calculation'. Computes the Average Daily Usage for all
+  Buffers.
+* 'Reordering Rule DDMRP calculation'. Computes the Qualified Demand, Net
+  Flow Position, Planning and Execution priorities for all Buffers.
+
+Decoupled Lead Time computation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The DLT is automatically computed by the system.
+
+For manufactured products' buffers just remember to provide and
+set properly the following information:
+
+* The *Manufacturing Lead Time* for the manufactured product. It can be found
+  at the product form view under the tab *Sales*.
+* The *Delivery Lead Time* for the preferred vendor of a product. This is
+  important for the products which are purchased and are components in any
+  Bill of Materials.
+
+For purchased/distributed products' buffers the logic is simpler.
+
+* In the first place the system will look if there are Vendors for the product,
+  if so it will use the *Delivery Lead Time* of the preferred one.
+* In case of absence of vendors, the *Lead Time* at the bottom of the Buffer
+  form view will be used.
+
+Usage
+=====
+
+To easily identify were are you maintaining buffers in your Bill of
+Materials, you will need to first provide location information on the Bills
+of Materials.
+
+* Go to *Manufacturing / Products / Bill of Materials* and update the
+  'Location' in all the Bill of Materials and associated lines,
+  indicating where will the parts be placed/used during the manufacturing
+  process.
+
+* Print the report 'BOM Structure' to display where in your BOM are you
+  maintaining buffers, and to identify the Lead Time (LT) of each product, and
+  Decouple Lead Time (DLT).
+
+
+Buffers
+~~~~~~~
+
+To list the list of inventory buffers, go to one of the following:
+* *Inventory / Master Data / Stock Buffer Planning*
+* *Inventory / Master Data / Reordering Rules*
+
+
+Buffer Profiles
+~~~~~~~~~~~~~~~
+Buffer profiles make maintenance of buffers easier by grouping them in
+profiles. Changes applied to the profiles will be applicable in the
+associated buffer calculations.
+
+* Go to *Inventory / Configuration / Buffer Profiles*.
+
+The Buffer Profile Lead Time Factor influences the size of the Buffer Green
+zone. Items with longer lead times will usually have smaller green zones, which
+will translate in more frequent supply order generation.
+
+* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor* to
+  chan
+
+The Buffer Profile Variability Factor influences the size of the Buffer Red
+Safety zone. Items with longer lead times will usually have smaller green
+zones, which will translate in more frequent supply order generation.
+
+* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor*.
+
+Usual factors should range from 0.2 (long lead time) to 0.8 (short lead time).
+
+
+Product attributes
+~~~~~~~~~~~~~~~~~~
+
+* For manufactured products, go to *Manufacturing / Products* and
+  update the 'Manufacturing Lead Time' field, available in the tab *Inventory*.
+* For purchased products, go to go to *Purchasing / Products* and update the
+  *Delivery Lead Time* for each vendor, available in tab *Purchase* and section
+  *Vendors*.
+
+
+ADU Calculation Methods
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The Average Daily Usage (ADU) defines the frequency of demand of a product in a
+certain location. It can be computed in different ways, which you can configure
+with ADU calculation methods as follows:
+
+#. Go to *Inventory / Configuration / DDMRP / ADU calculation methods*.
+#. Indicate a name, a calculation method (fixed, past-looking,
+   future-looking or blended).
+#. Fill the corresponding period (past, future or both for blended method) to
+   specify the length of period consideration (in days).
+#. Indicate the source of information: stock moves or demand estimates.
+#. If you use the blended method fill also the *Past Factor* and
+   *Future Factor*.
+
+If you do not have prior history of stock moves in your system, it is advised
+to use fixed method or start to work on future estimates. If you have
+past-history of stock moves, best use past-looking method or blended method.
+
+The ADU is computed every day by default in a background job independently
+from the other buffer fields. This computation can be done with less frequency
+but it is not recommended to run it less than weekly or more than daily.
+Circumstantially, If you need to force the calculation of the ADU go to
+*Inventory / Configuration / DDMRP / Run DDMRP* and click on
+*Run ADU calculation*.
