New supplier development e commerce logistics

Hello all,

I am stuck in a situation. I work in a logistics e commerce company and my managers have recently started seeing the potential benefits that quality management system can give and we are still in the first phase of planning the steps.
Meanwhile a new requirement has come to expand and add a new supplier which will in future serve as a partner cum manufacturing Center in our supply chain line.My boss has requested me to set up complete quality management regulations for this facility right from material inflow to sample tests to Reklamation and other quality management related tasks. How should I proceed as we still haven’t identified important processes and other operational problems at our company.What should be the important steps that I should consider with this and establish a quality management plan for this new warehouse of ours.
