Developing your own Pattern Libraries outlines an 8-step process to create a pattern library for an organization with multiple similar products: 1) identify common patterns, 2) research use cases and design patterns, 3) include variations of patterns across products, 4) document interactions, 5) include notes on flexibility and style, 6) keep patterns up-to-date, 7) ensure high-quality detailed patterns, and 8) continue growing the library for consistency and shorter design time.
