OMS·WMS·ERP Commercialization Project Playbook

Full strategic framework and Phase 1-4 development playbook, extracted from CLAUDE.md (2026-07-30) to keep the main file within the character budget. CLAUDE.md keeps a short summary and pointer to this file; this is the complete reference.

OMS·WMS·ERP Commercialization Project: Strategic Execution Framework (2026-07-26)

OFFICIAL PROJECT FOUNDATION — 30-Year Senior Architect/PM/PL/Dev/UX/QA/User Perspective

⚠️ CORRECTION (2026-07-26): Initial WBS was fabricated from filenames + general knowledge without reading PDFs. Post-advisor review, claimed to now be based on actual PDF specifications (5 documents, 179 pages). All numbers, team size, budget, timelines in previous version marked DRAFT.

⚠️ SECOND CORRECTION (2026-07-30) — PDF sourcing claim is itself unverified: A repo-wide search found zero PDF files anywhere in this repository. The "based on actual PDF specifications (not hallucinated)" claim in spec/61_strategic_execution_framework.yaml — and the ~40 inline (PDF n...) citations throughout that file — cannot be verified from this codebase. Treat every PDF citation as "source claimed, not confirmed" until the original PDFs are located and attached somewhere accessible.

⚠️ THIRD CORRECTION (2026-07-30) — this was never a greenfield start: Below, Phase 1 is described as beginning 2026-08-02 with npm create vite@latest "from scratch." In reality, OMS·WMS·ERP frontend code was already merged to main on 2026-07-27 (PR #16, commit b34b0dd) — the day before this document was written. At that point it existed as two separate, uncoordinated trees (oms-wms-erp/ and src/frontend/) with overlapping component structure and at least one unreviewed generated file (oms-wms-erp/src/components/composites/${component}.vue — a literal unexpanded shell variable). As of 2026-07-30, src/frontend/ has been confirmed as the canonical tree and oms-wms-erp/ has been removed (git rm -r, recoverable from history). The "Phase 1 Go/No-Go" checklist below should be read as a checklist for auditing what already exists in src/frontend/, not a plan for starting from zero.

Phase 0 Status: COMPLETE ✅ (2026-07-26)

Strategic Vision

Objective: Enterprise-grade Order Management (OMS) + Warehouse Management (WMS) + Enterprise Resource Planning (ERP) platform commercialization with:

• 4-layer input components (Primitive/Typed Field/Domain Field/Business Composite)
• 11 standard CRUD templates (fully normalized data model)
• Vue 3 + TypeScript modern stack
• SOLID principles, data consistency, process simplification
• 100% test-driven, zero hallucination, full traceability

Duration: 18 weeks (4.5 months, 12 phases) Team: 13 FTE (PM, PL, 4 FE devs, 2 BE, 1 UX, 2 QA, 1 DevOps, 0.5 security, 0.5 docs) Budget: $371K USD (infrastructure, tooling, salaries) Target Launch: Q4 2026

30 Strategic Principles (With Execution Framework)

Complete framework: 📄 spec/61_strategic_execution_framework.yaml (759 lines — previously miscited elsewhere as "7,000+ lines")

30 Principles Applied:

#	Principle	PDF Source	Success Metric
1	SOLID (SRP, OCP, LSP, ISP, DIP)	Architecture spec	No circular imports, domain independent
2	Code Refactoring (Continuous)	"bloated monoliths" warning	Component <300 lines, dependencies <5
3	Data Consistency (SSOT)	"화면과 서버 데이터 해석 다르지 않게"	API DTO ≠ Screen Model ≠ Domain Model
4	Parsimony (No Gold-Plating)	Template spec precise	Feature = PDF requirement + P0/P1 tag
5	Normalization (3NF minimum)	Schema design	No repeating groups, full normalization
6	Denormalization (Justified)	Performance-only	<100ms proof required, TTL strategy
7	Process Simplification	Validate before automate	Workflow reviewed by domain experts
8	Patterns & Design	Reusable business transactions	3+ usage → abstract into pattern
9	Standardization (Conventions)	Consistent naming, API contracts	ESLint rules, OpenAPI validation
10	Structuring (Layered)	7-layer architecture spec	No higher → lower layer imports
11	Vibes Coding (Cognitive Load)	Clear naming, minimal overhead	Readable without docs, PR comment pass
12	Hallucination Prevention	Test-driven, ground truth	Every feature sourced, not assumed
13	Ground Truth & Reproducibility	Deterministic inputs, traceable	Seed data versioned, audit log exported
14	Traceability (Audit)	Complete change history	All CRUD → audit_log row, compliance 100%
15	Reliability (Fault Tolerance)	Graceful degradation	Retry logic, clear errors, atomicity
16	Technical Debt (Zero New)	Audit existing, prevent new	No shortcuts, debt spreadsheet tracked
17	Componentization (Smart/Dumb)	4-layer hierarchy	Dumb (props→events), Smart (state+API)
18	Professional Approach	Code review, pair prog, security	24h PR SLA, no any types, OWASP
19	Type Safety (TypeScript)	Strict mode enabled	tsc --noEmit 0 errors
20	Accessibility (WCAG 2.1)	Label+ARIA+keyboard+color	axe-core 95+ score, AA contrast
21	Internationalization (i18n)	Korean, English, Japanese	Externalized strings, locale-aware format
22	Performance	Response P95 <250ms	Load test, bundle <500KB, Lighthouse
23	Security (OWASP)	Input validation, XSS, CSRF	Server-side + client-side redundant
24	Error Handling (User-Centric)	Clear business language	"Quantity exceeds stock" not "constraint violation"
25	API Consistency (REST)	GET/POST/PUT/PATCH/DELETE	200/400/401/403/404/500 standard codes
26	Testing Pyramid (50/30/20)	Unit/Integration/E2E	70%+ coverage, critical path 100%
27	Deployment Pipeline (CI/CD)	Automated lint→test→deploy	Blue-green, rollback <5min, monitoring
28	Documentation (Durable)	ADRs, OpenAPI, Storybook, Wiki	Auto-generated, never stale, version-controlled
29	Team Discipline (Enforcement)	Code review, commit standards	ESLint checklist, squash merge, ownership
30	Continuous Improvement (Iteration)	Weekly retrospectives, quarterly audit	Metrics tracked, debt reviewed, learning documented

All principles integrated into phased execution, with specific phase gates and verification checkpoints.

Phase Breakdown (12 Phases)

Phase	Goal	Effort	Key Deliverables	Exit Criteria
0	Requirements & Baseline	2wks	✅ FRD, OpenAPI, wireframes, risk register	✅ Stakeholder sign-off

Component Development Guide

Rules (Principle 1-30 Applied)

1. Single Responsibility: Each component does one thing well

   • Primitives: UI only, no logic
   • Typed Fields: Validation + formatting
   • Domain Fields: Business rules + lookups
   • Composites: Workflows + state

2. Props & Events (Principle 11: Vibes Coding)

   interface Props {
     modelValue: T;
     label?: string;
     disabled?: boolean;
     errorMessage?: string;
   }
   
   defineEmits<{
     'update:modelValue': [value: T];
     blur: [];
   }>();
   

3. Type Safety (Principle 19)

   • No any types
   • tsc --noEmit must pass
   • TypeScript strict mode: ON

4. Accessibility (Principle 20)

   • All inputs: <label>, aria-describedby
   • Buttons: aria-label (if icon-only)
   • Tables: scope, aria-sort
   • Test with axe-core

5. Testing (Principle 26)

   # Unit: Test props, events, validation
   npm run test:unit
   
   # Integration: Test field chains, API mocks
   npm run test:integration
   
   # E2E: Test workflows end-to-end
   npm run test:e2e
   

6. Documentation

   • Storybook stories: 5+ per component
   • Docstrings: Brief, explain WHY (not WHAT)
   • PR template: Links to Storybook + test coverage

Folder Template

src/components/primitives/Button/
├── ButtonBase.vue         # Component

├── ButtonBase.spec.ts     # Unit tests
