ES-105 Outputs

Purpose

This page defines the outputs produced by ES-105 and how they support later stages.

Required outputs

docs/design/design_overview.md
docs/design/interface_design.md
docs/design/data_design.md
docs/design/workflow_design.md
docs/design/access_control_design.md
docs/design/ai_interaction_design.md
docs/design/error_and_exception_design.md
docs/design/technical_decision_records.md
docs/design/design_review.md
docs/design/design_readiness_summary.md

Output purposes

Output Purpose Downstream Use
Design overview Establishes design goals and sources. Implementation readiness
Interface design Defines component contracts. Implementation and testing
Data design Defines structures and evidence fields. Implementation, testing, governance
Workflow design Defines system behavior and transitions. Implementation and testing
Access-control design Defines authorization behavior. Implementation, security testing
AI interaction design Defines AI handling and human review. Implementation, AI verification
Error and exception design Defines failure behavior. Implementation, testing
Technical decision records Preserves design rationale. Maintenance and review
Design review Records findings and corrections. Readiness decision
Design readiness summary States ES-106 readiness. Implementation readiness transition

Optional outputs

docs/design/ui_flow_notes.md
docs/design/api_contracts.md
docs/design/data_dictionary.md
docs/design/state_machine.md
docs/design/open_design_questions.md

Create optional outputs only when they clarify real design evidence.

Output quality checklist

Confirm every required artifact exists, design traces to architecture, interfaces are clear, data structures include evidence needs, workflows include failure behavior, access control is explicit, AI interaction is explicit or not applicable, technical decisions are recorded, design review is complete, and readiness for ES-106 is clearly stated.

Common pitfall

Do not mistake detailed implementation notes for design clarity. Design should explain technical choices, not dump coding instructions.

Engineering insight

The best design outputs make ES-106 less subjective.
