  • Comments on Brightwork Articles on Demand Sensing in Forecasting

    ByPrimary Researcher

    … supply plan cannot respond. So no, just because you can improve a forecast accuracy is immaterial to whether you should improve a forecast that cannot be met. The last part of your response lost me. Demand planning can be changed up down and sideways…..up until it impinges on the supply planning lead times. After that point, it may not be changed because at that point the horse has left the stable. So, unfortunately, Tibor, I still don’t see any logic under any circumstance where demand sensing makes any sense and should be performed. (although I am still open …

    Great comment John. You demonstrate a lot of the nuances of cost optimization. Please send me a shipping address and I will send you a copy of “Supply Planning with MRP, DRP, and APS Software.” Given your real-world experience in cost optimization, I think you will enjoy the book. I am not sure as to the publication date but am close to getting it out.

    … supply lead times as “cheating” and also potentially dangerous — giving the organization a false sense of how well they can truly forecast their business.”
    Thanks for the comment Mike, I completely agree. Changing forecasts inside of the lead time is really just a tool for supply planning to perform “housekeeping,” as you write — it’s not a forecasting approach.

    How Multiechelon Methods or Software Are Normally Judged
    Normally it is understood that all supply planning methods deal with supply chains as they are multi echelon by their nature. However, the ability to intelligently plan around the interactive location component is a specific subcategory of supply planning software with unique multi echelon mathematics.
    We cover this mathematics and the outcome for supply planning. How …

  • How is DDMRP Buffer Stock Different from Safety Stock?

    DDI on Buffer Stock
    The following is a video explaining the buffer stock concept by the DDI.

    Decoupling Points and Decoupling
    DDMRP uses the term decoupling points, which will be (and should be) confusing to many, but this is simply the buffering of demand with the inventory. All supply planning systems — unless they are made to order, use decoupling points. However, be careful in assumptions in this area. As we will see, the DDI has chosen to use the term “buffer” in a very peculiar way.
    The video states that ordering is performed along with actual demand and …

  • How Accurate is DDMRP's Explanation of Forecasting?

    ByPrimary Researcher

    … when executives see that this is now DDMRP, apparently many of them think that it is ok?
    Furthermore, part of nearly every product location database does have a good forecast accuracy. Are we to also put these product locations on DDMRP as well? I cover in the book Multi-Method Supply Planning in SAP APO, that one can assign different product locations different strategies.
    Unwarranted Animosity to DDMRP?
    I can continue with many more aspects. In few words, forecast is not an enemy or just a simple friend of DDMRP. It is one of the best ones. Sometimes, the only …

  • How the Demand Driven Institute Tries to Make DDMRP Unfalsifiable

    ByPrimary Researcher

    Executive Summary

    The Demand Driven Institute has some rules they would like you to follow when critiquing DDMRP.
    If you follow them, DDMRP cannot be critiqued.

    Introduction
    The Demand Driven Institute, led by Chad Smith and Carol Ptak, makes significant efforts to stop those with extensive experience in the MRP, forecasting, and supply planning space from critiquing their creation of DDMRP. By observing multiple interactions and debates, mostly on LinkedIn, the Demand Driven Institute’s strategy has become apparent.
