Operational Data Trend Forecasting
Budget: €12 – €18 EUR
I am working with a sizeable set of enterprise-level operational data and need a clear, defensible forecast of upcoming trends. Everything will be handled in Excel—no BI suites or code this time—so the entire workflow, from cleaning through modelling to final visualisation, must live inside a well-structured workbook.
The primary scope centres on our operational metrics, yet the approach should remain flexible enough that I can later slot in sales or customer figures without re-engineering the model. Accuracy and transparency are critical: every assumption, formula, and transformation step must be traceable so managers can audit the logic.
Key deliverables
• A master Excel workbook containing raw data staging, cleaned tables, forecasting model, and dynamic charts
• A brief methodology write-up (one-pager is fine) outlining assumptions, statistical techniques, and how to refresh the model with new data
• A concise slide or dashboard view built in Excel for quick stakeholder updates
Acceptance criteria
• Forecast error metrics (MAPE or similar) clearly displayed and within agreed thresholds
• No external add-ins or macros that can’t run on standard Office installations
• All calculations labelled and intelligible to a non-coder analyst
If you can bring rigorous forecasting discipline into a pure-Excel environment while keeping the file usable by everyday staff, we’ll be a great fit.
