Financial modeling discipline: Build clean, auditable models with clear inputs/outputs, version control, and sensitivity analysis.
Automation with Macros/VBA: Record macros, then learn basic VBA to automate reconciliations, imports, and report refreshes.
Power Query and Power Pivot: Reshape messy data, relate tables, and build robust models that refresh in seconds.
Practice and updates: Keep pace with new functions and features; rehearse on real business scenarios, not just tutorials.
These sharpen both speed and accuracy—two levers every cost leader needs.
