原创 What is Driving Excess Materials?

Our Fiscal Q2 ended yesterday, we have done whatever we can
do, such as stopping materials in-take, stopping production if we can not ship
it out within Feb, disposing onhand inventory in all possible means especially
RTV, RTC… yes, we made every effort! And now, a brand new Quarter begins, we
are still
perturbed in mind, but pretending to be strong, praying
secretly for the desired Q2 ending DII.



Actually, the battle for DII defense started earlier than we
thought. It is time for us to go through all key factors impacting DII once
again.



  1. Business Environment : Make-to-order/Make-to-stock /Assemble-to-order/Configure-to-Order

    Nowadays,
    we have the above all kinds of business modules, especially the last two kinds,
    it requires-





  • Specific
    products are configured based on many possible options

  • Many
    manufacturing companies fit into this, including automobiles and computer
    systems companies.

  • Semi-completed
    goods are stocked, completed upon received of customer PO’s.

    These
    business modules will mainly define when we can produce the product( changing
    the raw components to Finished goods), and when we can transfer the FG
    inventory from we owned to customer owned. We have to rely on business guys a
    lot on this area, to push customer place orders for us to arrange production, to
    push customer to pull the FG from HUB( 3rd party warehouse), to get
    a better Inco-terms for inventory liability transfer point…

    2. MRP Input:



  • MPS

  • BOM

  • Inventory data

  • Planning
    parameters
    ---Planning parameters include lot size, lead-times (internal
    manufacturing lead-time, goods receipt process time, external materials
    lead-time, order release lead-time), scrap factors (loss percent), safety
    stock, ABC Classification, MOQ, SPQ, Media requirement  etc.



What is MRP? Material
Requirements Plan
, the
time phased Explosion of the material requirements based on the Bill of
Materials, Lead Times, Order Quantities and Safety Stocks to determine what to make or buy and when.
 Normally,  
MRP = Demand – Supply






 Note: Any change on
above items can impact the MRP, resulting in critical shortages or
excess/obsolete materials if managed without a proactive plan.   MPS
is to drive the necessary resources to assure customer satisfaction while minimizing
liability to us.



        MRP should be driven by the Master
Production Schedule,



  • What raw material or components are required for
    a product

  • What quantity those materials are needed

  • When the material must be physically available
    for production.

    Let’s look at how we do it!

  • And let’s see how MRP works – we can see that the Inhouse
    production Lead time will all add up to the total Leadtime. One of the primary
    opportunities to prevent early material pull-in is keeping the proper Manufacturing
    inhouse correct in SAP. If the BOM is not layered correctly it will drive
    inventory early. I we take weekly build lot size, the lead-time is less likely
    just “7 days”. The Material team, very importantly, need to stay very tight on
    the “true” in house parts lead-time and proper BOM structure.




Yeap, here it is Q3, a new round of PDCA! First thing First!
We have to ensure our PLAN is correct 

– 1)BOM,

2) Planning parameters  especially Leadtimes,




3) MPS( aligned with revenue projection & resources
capability).




And then the rest is just EXECUTION! No matter what Q2 end
is like, let’s now fight for a better Q3!

There is no fix all, and there's no one-step solution. But we can get started with a big scope but taking step by step progress!
