Methodology

Design patterns don't fail because they're wrong — they fail because developers reach for them at the wrong moment. Instead of memorizing all 23 Gang of Four patterns, this tool uses a pain-point-first decision tree: describe the friction you're trying to remove, then follow targeted questions to find the right pattern.

Attribution

This project is inspired by “Stop Memorizing Design Patterns: Use This Decision Tree Instead” by Alina Kovtun, published on Medium's Women in Technology publication. The article proposes a decision tree covering 17 of the original Gang of Four design patterns across three categories: Creational, Structural, and Behavioral.
