Cooperation is essential for any successful business partnership, so it is important for owners and contractors to develop written and oral communication protocols. A quality agreement should define all manufacturing roles and activities and establish appropriate contact staff for each organization. Processes such as corrective and preventive measures (CAPA) and deviation management have the potential to create disagreements, so responsibilities related to studies and other processes related to the management of the quality event should be clearly defined in the agreement. The guidelines also stress that quality agreements should be clear as regards the release of products. .
