To the layman, yes, every NTC employee should be concentrating on fulfilling the existing orders.
To someone like myself who works in the industry, yes, but because the component and product manufacturing is outsourced there is likely nothing that the engineers at NTC can do to speed up fulfilling the existing orders. With respect to the NAND delays, the main time loss was waiting for weeks long validation tests to complete. I have personally felt bad about both of these types of situations affecting my customers but realistically there is nothing I or the others at my employer can do, so we work on other projects and monitor the situation.
Since the NTC employees can't actually do anything to speed up the fulfillment they instead do the things they can do, design new products, promote the existing products, etc. My guess is that the C.H.I.P. Pro system of hardware and software has actually been in active development for quite a while and its development has not taken away any resources required to fulfill orders. I suspect if anything the NAND issue took developers away from the Pro project right at a time when things where finally coming together (Murphy's Law strikes again ).
