Can a new source win this part?
DLA buys this part directly from the actual manufacturer.
Acquisition method 3 means DLA buys directly from the actual manufacturer, not through open competition. DLA's code says the government does not have sufficient, accurate or legible data to buy it from other sources.
Next step: Expect the buy to go to the sources already listed for this part. A new shop would usually need its own approved drawing and a source approval before it could win.
