Automated KPI Dashboard with Dynamic Time Comparisons and YoY Growth

This Excel pattern builds a KPI dashboard that dynamically compares current period performance to prior period and year-over-year benchmarks. Design a data model with normalized metric rows and a calendar table. Compute period aggregates using SUMIFS or a pivot and calculate delta and percent-change measures for M/M and Y/Y. Use slicers for period selection and conditional formatting to highlight key performance signals. Add small multiples charts for metric groups and KPI cards with trend sparklines. For large datasets, load into the Data Model and use DAX measures to handle time intelligence robustly. Document calculation logic and ensure time zone consistency when measuring web metrics.
