Elaboration Phase

The phase in which the system’s structural backbone is established by advancing analysis and design based on the requirements and directions defined in the inception phase. In the AI era, its most critical role is to refine context, boundaries, and assumptions, eliminating ambiguity and contradiction, and to establish the architecture baseline referenced by the AI.

In SimpleModeling, the elaboration phase is the core phase where models are elevated into executable knowledge structures. Through analysis and design models, structures, responsibilities, and relationships are fixed, explicitly defining boundary conditions that allow AI to generate without making design decisions.
