2. Verify material lined up to support orders and forecasts
3. Calculate monthly [$] materials demand
4. When ordering against forecasts advise program management of material liability

  • Ensure material is underwritten by customer
  • Do not order materials against forecasts if it is not underwritten by the OEM. Requests must be seen in writing / email. Verbal requests are not sufficient, either from program management or from the customer


New OEM orders from existing programs
EMS program management supplies EMS purchasing copies of all new orders which are then used to:

  • Check raw materials pricing (costs) and requested vendor delivery dates
  • Compare with forecasts, advise materials of implications of any mismatches
  • Confirm orders are consuming the forecast
  • Status critical parts and long leadtime items
  • Within two (2) days receiving orders, advise program management of anticipated start date for the order
  • Ensure order is entered into system in-line with start date before actioning ERP
  • Measure performance against agreed on completion dates from program management, planning, and manufacturing


Treat OEM reschedule requests similar to new orders, taking the following actions:

  • Compare existing date with new request date
  • Schedule pull-ins: status material and advise a start date
  • Schedule push-outs: calculate the value of inventory being held
  • Get appropriate EMS functional groups in decisions whether to charge inventory carrying costs
  • Respond to reschedule requests within two (2) working days

  • Status the stock-on-hand and the stock-on-order of the deleted part(s)
  • Advise program management of new part cut-in date, any obsolescence costs
