Weighted Performance Scoring Model

This task helps data analysts build weighted scoring models for performance evaluation, vendor selection, or KPI benchmarking. By applying SUMPRODUCT, different metrics can be weighted according to business importance, producing a single normalized score. This method is widely used in decision science and is easy to explain to stakeholders. Analysts can dynamically adjust weights to simulate scenarios without rewriting formulas. When combined with data validation and conditional formatting, the model becomes a powerful decision-support tool. It avoids black-box calculations while remaining flexible and scalable. The formula works across Excel and Google Sheets, making it suitable for cross-team collaboration.
