Architecture before requirements — with tradeoffs explained
System design as a gated planning stage — components, data flows, APIs, and technology choices with tradeoffs explained, before requirements and backlog.
Architecture outputs
FLOWiGANTT describes services, integrations, data stores, and API boundaries from approved evaluation and feature context — so the PRD and backlog that follow inherit the same structural decisions.
Downstream planning
Approved architecture feeds the PRD, user stories, and engineering tasks. Teams see how scope maps to components before estimating or exporting work items.
Clarity for humans and assistants
Structured architecture text helps developers, PMs, and LLM-based tools answer “how does this system fit together?” with consistent terminology.
