Dynamic Customer Segmentation Waterfall Scorecard in Excel

Create a multi-dimensional customer segmentation model using Excel's advanced conditional formatting and scoring algorithms. Design a dynamic scorecard that automatically categorizes customers into segments (high-value, medium-potential, at-risk) based on weighted attributes like purchase frequency, total spend, recency, and engagement metrics. The model should use nested IF statements, VLOOKUP for dynamic scoring, and a color-coded visualization that updates automatically when new data is imported. Include a methodology for periodic recalibration of segmentation thresholds.
