One of the most important things to have included in a vendor contract is the condition that they need to notify your company about any changes that they have made or are going to make to the components that they supply to your company. These changes can range from a change to the overall design, a change in tolerance, a change in material, and a change in quantity per order. It is important for your company to be notified because changes in the manufacturer’s design of the component can affect the final product that you are producing and putting on the market.
