Without a formal system, vendor management relies on memory and gut feeling, leading to inconsistent decisions and potential supply chain risks. A numeric rating system helps you: The PinguBuy system is based on three critical performance pillars. Rate each on a consistent scale (e.g., 1-5 or 1-10). A simple table structure is powerful. Here's a conceptual blueprint: With your rating system active, you can now segment vendors: By leveraging the PinguBuy spreadsheet method, you build a data-driven foundation
