Logical thinking and systematic problem solving: Maybe K. Rawiphan has few occasions to speak English, or else, she has little opportunity to tackle problem by her own. My observation was:- she had difficulty to understand issue/ problem and was not able to address her logical thinking to analysis and identify the root causes of the problem. Then, use a systematic approach to tackle the problem with appropriate solutions. (Most Operational engineers are pretty good in these areas but I saw a weakness with K. Rawiphan).
