Re: Forecast vs. build

No exact answer, just areas to think about.

We are a make to order job shop and engineer to order in which it takes a 
while to get the engineering right on brand new customer parts, but we know 
early on what raw materials will be needed.  Once the customer approves our 
samples, they need production NOW.  We enter the BOM as soon as we have an 
idea, although the BOM will be revised once the Routings are defined, and we 
enter the customer order or forecast, which means that MRP drives raw 
material demand through Purchasing while Shop Floor Control is supposed to 
know to disregard requirements where there are no Routings yet.

Our Order Type Policy is for Customer Orders to consume Forecast.

We currently use safety stock on some raw material items.
We have been discussing, but have not implemented, safety stock on 
sub-assemblies where the setup times are high & the items are often needed.

The big problem that I see is where Production Planners want to release 100% 
Shop Orders that MRP says is due, when in fact we have customers that are 
slow to decide if samples are right or need further design work & other staff 
at same customers are asking for the parts like yesterday.  There needs to be 
clear communication ... this data is in BPCS but do not do it yet.  Also we 
have to be careful with effectivity dates.  They default to date of entry, 
but need to be back dated so MRP will correctly plan the new stuff.
