Had similar situation with a client ~12 years ago. R&D and Marketing cold not understand Production delays, I helped them see the impact of R&Ds too tight specifications had on getting materials in the quantities needed and the impact of Marketing's customization of labels had on getting labels from the printer in time for packaging. Everyone points their finger at production - it is the most visible, and don't understand their role. Production can do little without the collaboration of almost every other function in the organization. The real work happens horizontally across the organization not vertically down the functions.
