This is life

Hi Mandy, Michelle,

What you are talking is about PP and MP stage. R&D will release official BOM for PMC to monitor the materials status.

As I know that PMC is not responsible to monitor the materials status in ES and EP stage, so R&D have to take the responsibility to take care all these un-confirmed items. Before create a BOM, we have a E-BOM as a transition buffer for ES and EP stage to make sure all these items are qualified then put into official BOM. This is our general practice.

Right now the situation is Customer provides a very short developing period for us, it is hard for you to monitor the status because there is no BOM, it is also hard for us to convince ourselves to qualify all the items without testing. According to our experience, it must be a lot of changes during ES and EP stage (otherwise we don't need different stages),but nobody will care the internal process time how long to revise a single item but just keep pushing R&D to fulfill customer's request. Therefore, in order to minimum the risk for wasting manpower and time, we have to have analysis first, that's mean ES and EP, then release official BOM.

OK, solution.

Customer confirmed 90% materials are fixed especially PCB at this moment (ZERO change), then we will release FO BOM.
MKT input item by item due to customer wants to buy first but also don't want to approve the item, risk is too high for R&D.
R&D release FO BOM now, but MKT and customer and top management have to understand that EP and PP must be delay from now on if there are any changes. We really need time to process the huge workload if there are any changes, we are not magician.
