I will hand you a raw Excel/CSV file and need it transformed into clear, decision-ready intelligence that speaks directly to our business-strategy questions around sales performance. The work begins with thorough cleaning—handling missing values, outliers, and inconsistent formats—then moves into processing and feature engineering so the data is structured for analysis. From there, I’d like to see exploratory visualisations (Python, R, Power BI or Tableau—use whichever you are strongest with) that surface patterns and relationships at a glance. Ultimately, you will extract the key insights that tell us what is really driving results and where opportunities lie, then package everything so executives can act on it immediately. Deliverables • Cleaned and well-documented dataset • Interactive or well-annotated visual dashboard focused on sales performance metrics • Concise insight summary highlighting the implications for business strategy, backed by the figures and graphics you produced Acceptance criteria: findings must be reproducible from the code or notebook you provide, and every chart should link clearly to at least one strategic recommendation.
