# Established the mathematical foundation with the Newsvendor model ## Foundation: Mathematical Metaphor **Core Contribution:** Introduced the Newsvendor model as a framework for entrepreneurial decision-making **Key Concepts:** * Underage costs (Cu) vs. Overage costs (Co) * Critical ratio: r = Cu/(Cu+Co) * Stakeholder sequencing problem **Mechanism:** Translated abstract stakeholder prioritization into concrete optimization problem --- ## Context from Evolution May established the mathematical foundation that would evolve through June and July: - **May (peach)**: Newsvendor model foundation - **June (blue)**: Added strategic complexity → [[2025-06]] - **July (green)**: Final synthesis with "Promise Vendor" → [[2025-07]] ### Key Insights 🔄 **Progressive Refinement**: This month established the mathematical foundation that June would add strategic complexity to, and July would synthesize into the final "Promise Vendor" concept. --- *Source: Extracted from [[2025]] using [cld](https://claude.ai/chat/7fee518c-b641-469f-9514-374748a8a350)*
