Yimei Chan developed data analysis and reporting skills to help improve business processes at D-Link. She quickly learned their new QlikView data software and took over extracting and analyzing data to create product reports, market analyses, and opportunity analyses. Chan further developed her Excel skills and created macro-enhanced tools like a data analyzer and business process monitors for end-of-life products and sample control. These tools provided clearer and more efficient analytics and monitoring to benefit decision making.
