TRA-210 Implementation Plan Template (Pending Lastenheft Inputs)

Status: blocked until Lastenheft and board constraints are provided. Owner: CTO

1) Required Inputs

• Lastenheft source: <repo path or URL>
• Scope constraints: <in/out of scope>
• Timeline constraints: <milestones / deadlines>
• Preferred delivery phases: <phase model>
• Workspace completeness confirmation: <yes/no + details>

2) Decomposition Workflow

1. Parse and normalize Lastenheft requirements into atomic requirement IDs.
2. Map each requirement to architecture domains and subsystems.
3. Define MVP boundary and phase slicing.
4. Derive implementation epics from grouped requirements.
5. Break epics into execution-ready backlog tickets with acceptance criteria.
6. Sequence dependencies and identify critical path.
7. Define QA gates, release criteria, and rollout plan.

3) Backlog Structure

For each ticket:

• Title
• Requirement IDs covered
• Description
• Acceptance criteria (testable)
• Dependencies
• Estimated effort (S/M/L)
• Owner role
• Target phase

4) Execution Phases (Draft Skeleton)

• Phase 0: Discovery and requirements normalization
• Phase 1: Core platform and foundational services
• Phase 2: Feature delivery wave 1 (MVP)
• Phase 3: Feature delivery wave 2 (enhancements)
• Phase 4: Hardening, compliance, and release

5) Risks and Controls

• Missing/ambiguous requirements -> requirements clarification log
• Scope creep -> strict requirement-to-ticket traceability
• Integration unknowns -> early technical spikes
• Quality regressions -> mandatory test gates per phase

6) Definition of Ready/Done

Definition of Ready:

• Requirement mapping complete
• Acceptance criteria defined
• Dependencies identified

Definition of Done:

• Acceptance criteria verified
• Tests passing
• Documentation updated
• Traceability to Lastenheft requirement IDs recorded
