ES-103 Outputs¶

Purpose¶

This page defines the outputs produced by ES-103 and how they support later stages.

The output of ES-103 is not a schedule alone. The output is a planning evidence package that makes work, ownership, dependencies, risks, estimates, reviews, and readiness visible in the repository.

Required outputs¶

docs/planning/planning_overview.md
docs/planning/work_breakdown_structure.md
docs/planning/milestones.md
docs/planning/roles_and_responsibilities.md
docs/planning/risk_register.md
docs/planning/dependency_map.md
docs/planning/estimation_record.md
docs/planning/planning_review.md
docs/planning/planning_readiness_summary.md

Output purposes¶

Output	Purpose	Downstream Use
Planning overview	Connects requirements to planning assumptions and objectives.	ES-104 architecture readiness.
Work breakdown structure	Defines traceable work packages.	Execution, tracking, reviews, architecture scoping.
Milestones	Defines evidence-backed readiness checkpoints.	Progress control and stage transitions.
Roles and responsibilities	Defines ownership.	Accountability and review responsibility.
Risk register	Records planning and execution risks.	Risk management and architecture tradeoffs.
Dependency map	Shows sequencing and blockers.	Architecture, implementation, testing, and release planning.
Estimation record	Records estimates and uncertainty.	Scheduling, tradeoff decisions, and scope management.
Planning review	Records review findings and corrections.	Plan correction and risk reduction.
Planning readiness summary	States ES-104 readiness.	Primary transition artifact into architecture.

Optional outputs¶

docs/planning/backlog.md
docs/planning/sprint_plan.md
docs/planning/open_planning_questions.md
docs/planning/ai_planning_notes.md
docs/planning/planning_change_log.md

Create optional outputs only when they clarify real planning evidence. Do not create extra files to look complete.

Output quality checklist¶

Confirm that every required artifact exists, work packages are traceable, major work has an owner, dependencies are visible, risks are assigned, estimates include uncertainty, review findings are recorded, unresolved issues are visible, and readiness for ES-104 is clearly stated.

Downstream consumers¶

ES-104 uses ES-103 outputs to understand the work architecture must support. Later stages use the planning package to track implementation, verification, review, release readiness, operations, and governance commitments.

The planning package should therefore remain useful after ES-103 ends. If later stages cannot use it, it is not strong evidence.

What should ES-104 receive¶

ES-104 should receive:

a clear requirements baseline;
a decomposed work model;
known constraints;
known dependencies;
visible risks;
ownership expectations;
evidence obligations;
estimation uncertainty;
unresolved planning issues;
architecture implications.

Lifecycle chain¶

The ES-103 output chain is:

Requirements obligations
  ↓
Planning evidence package
  ↓
Architecture readiness
  ↓
ES-104 architecture work

Common pitfall

Do not hide unplanned work in vague categories like “integration” or “testing.” Break it down enough to review and manage.

Engineering insight

Outputs are not paperwork. They are durable engineering memory that later stages should be able to trust, challenge, and use.
