Diana Yang is a professional in their field. They is proficient in English. Colleagues describe them as "Diana is a smart program manager. Her management skill is proven by her success in Dell PM team and I don't need to prove it again. Yet I'd like to share one observation: Diana keeps very good relationship with her suppliers. As a PM in Dell, she got a lot power over Dell's suppliers and could abuse it if she wanted. However, it didn't happen to Diana and most business partners support her leadership. I believe this is one important factor behind Diana's success."
