What Annette demonstrated

Built an end-to-end profit investigation that framed the paradox with hypotheses and a KPI driver map, validated the data, and answered the core SQL questions with the correct margin logic. The analysis isolated raw-material inflation, logistics inefficiency, and discounting as the main drivers, then translated those findings into a quantified recovery forecast and a clear executive recommendation set.
