DDMRP in Excel Starter Pack

Everything you need to set up a DDMRP implementation. 
With Software that you already own – Excel.

Here is Why You need this

DDMRP is a process.  To be successful, requires an understanding of the process and the experience of it working at scale.  A pilot project is crucial.  If you have 100’s or 1000’s of parts, it is not sustainable to do it all manually.  And a valid pilot project needs to demonstrate sustainability.  However, if you want to implement DDMRP in software,  you will need $50,000 investment and a minimum of 6 months.  And it is difficult to make that business case without a successful pilot!

The DDMRP in Excel Starter Pack uses software you already have: Microsoft Excel.  You will get a set of workbooks that operate as a system – calculate buffers, generate supply orders and produce reports – all at the at the click of a button.  We have done all the development and formulas so you don’t have to.  Leaving you free to get the process of DDMRP working in your company.

Calculate the Decoupled Lead-Time and choose items to buffer that give the best service levels to the customer.

Group parts into families and calculate buffer zones so that you put inventory in the places that need it the most.

Dynamically alter buffers to respond to future events.

Calculate Net Flow and Identify New Supply Orders.  Prioritize existing orders based on Net Flow Status.

Real-Time alerts on buffer status based on the on-hand position.  Track inventory performance against buffers to evaluate and improve planner behaviours.

Frequently Asked Questions

Yes.  To get the your own data in the system there are three options:  Cut and Paste, connect to text files and connect to a database.  We strongly recommend the connection methods.  The system comes with a Data Interface module that can be set up to perform Extract, Transform and Load operations without any database programming required.

This system is designed for discrete manufacturing.  Any process that is producing standard discrete items will fit, in principle.  It may also support some process manufacturing (food, chemicals, pharmaceuticals).  

Customized manufacturing like a job-shop may need a special extension.  Please contact [email protected] for more details.

No.  A Make-to-Order business will have finished goods inventory and this can be a natural target for inventory positioning and buffer sizing.  Many companies start with raw materials.  The DDMRP in Excel system supports both Make-to-Stock and Make-to-Order production.

This system is designed to be deployed in a full-scale manufacturing business with hundreds and thousands of items and BOM records.  We have deployed it with 100K+ rows of data and it can run that load in a few minutes.

Yes.  The system will explode the BOMs to every level.  The most we have come across is 13 levels (for a helicopter) and the standard system will run to 20 levels.  If you need more, just ask!

The full data requirement will be covered in detail in the first course module.  In brief, it will be an item master, demand history, open sales orders, Bills of Material, open purchase orders and inventory.  If you are running MRP or any kind of material planning then you will already have much of this.  The DDMRP in Excel system comes pre-populated with example data.

This Starter Pack is intended for people with basic to intermediate Excel skills.  If you know how to use formulas like SUMIF and know the basics of a pivot table then this is ideal.  Included in the Starter Pack is the Fundamentals Course for the Fast Excel Development Method and Template.

Yes, if all users are on a local area network, have access to a shared drive or cloud folder like Dropbox.  The system is set up to handle data from a single central place and does not depend on shared Excel workbooks which can have severe limitations on simultaneous usage.

Little to none.  If you require to connect to a host ERP or Accounting system, then you will need someone to write a scheduled task to export data in text files or provide a connection to the database.  That is all.  If you run the system with manually compiled data, then you will not need any IT support at all.

A copy of Excel 2003 or above.  A Windows 10 PC or laptop with basic specification.  Older versions of Windows can be supported by request.

Production-Scheduling.com is run by consultants who are on-hand to provide additional support.  There are flexible packages that allow you to access one-on-one or small group support or development starting from $250.
