ADLC Workflow

Every task follows the same coordination pattern. No exceptions.

The Golden Rule

HITL/Manager → Product Owner → Cloud Architect → Specialist → Evidence

1. You (HITL) give a directive
2. Product Owner validates requirements and priority
3. Cloud Architect designs technical approach
4. Specialists execute (infra, QA, security, etc.)
5. Evidence collected in tmp/<project>/

Six-Phase Lifecycle

PLAN → BUILD → TEST → DEPLOY → MONITOR → OPERATE
 [A]    [A]   [HITL]  [HITL]   [HITL]    [HITL]

[A] = Autonomous    [HITL] = Requires your approval

Phase	You Do	Agents Do
Plan	Describe what you want	Decompose into stories, create ADRs
Build	Review progress	Write code, IaC, tests
Test	Approve test plan	Run Tier 1/2/3 tests
Deploy	Approve deployment	Execute terraform/cdk apply
Monitor	Review dashboards	Set up alerts, SLOs
Operate	Handle incidents	Create runbooks, playbooks

Quick Start Examples

New Feature

You:  "Add S3 bucket with encryption for audit logs"
      ↓
      Product Owner validates requirements
      ↓
      Cloud Architect designs (CDK vs Terraform, encryption type)
      ↓
      Infrastructure Engineer implements
      ↓
      QA Engineer tests (Tier 1 → 2 → 3)
      ↓
      Evidence in tmp/<project>/

Using SpecKit Commands

# 1. Define the feature
/speckit.specify "Add encrypted S3 bucket for audit logs"

# 2. Plan the implementation
/speckit.plan

# 3. Generate tasks
/speckit.tasks

# 4. Execute all tasks
/speckit.implement

# 5. Reflect on the session
/speckit.retrospective

Infrastructure Deployment

# Terraform workflow
/terraform:test          # Run all test tiers
/terraform:cost          # Estimate costs
/terraform:diff          # Check for breaking changes

# CDK workflow
/cdk:test               # Run all test tiers
/cdk:synth              # Validate synthesis
/cdk:diff               # Check for breaking changes

Evidence Directory

Every action produces evidence:

tmp/<project>/
├── coordination-logs/     # PO + CA approval records
├── test-results/          # Tier 1/2/3 results
├── screenshots/           # Visual verification
├── terraform-plans/       # IaC plan outputs
└── retrospectives/        # Session reflections

Anti-Patterns to Avoid

Don't	Do Instead
Skip PO + CA coordination	Always invoke both first
Claim "done" without evidence	Put artifacts in tmp/
Describe what you'll do (NATO)	Show what you did
Deploy without testing	Run Tier 1 → 2 → 3
Ignore session learnings	Run /speckit.retrospective
