Modeling

Low-tech collaborative workshop; 10-step process (domain events, commands, policies, aggregates, bounded context candidates); when to use; two-phase facilitation; remote considerations; Rosa: Big Picture EventStorming for domain boundary/KPI mapping + KPI Value Tree; Process Modeling EventStorming for operational value stream analysis

Evans' binding principle: one model for analysis and design; code is the model's expression; hands-on modellers; bones-showing; requires layered architecture for domain isolation; breakthroughs: non-linear returns, cascade of insights, Share Pie story

DDD cornerstone practice: shared business language eliminating translation chains; must pervade the code; modeling out loud; documents must track UL or be archived; UML limitations; explanatory models as separate teaching aids
