# Angular Migration Business Case Template

**Prepared by:** [Your Name], [Your Title]
**Date:** [Date]
**Application:** [Application Name]
**Current Angular Version:** [e.g., Angular 12 / AngularJS 1.x]
**Target Angular Version:** [e.g., Angular 19+]

---

## 1. Executive Summary

**Risk:** Our [application name] runs on [current version], which [has not received security patches since X / is X major versions behind / uses patterns that block modern tooling]. The annual cost of inaction across security, hiring, velocity, and opportunity is estimated at **$[total]**.

**Investment:** A phased migration over [X months] requires an estimated **$[total]** across three phases, with the first phase costing **$[Phase 1 cost]** and producing a validated migration plan.

**Return:** Migration eliminates **$[annual cost]** in compounding annual costs, improves development velocity by an estimated **[X]%**, and enables [specific capabilities not currently possible].

## 3. Migration Plan

### Phase 1: Assessment and Pilot (4-6 weeks)

- Structured diagnostic across 5 modernization dimensions
- Pilot migration of one low-risk module end-to-end
- Detailed migration roadmap with effort estimates
- **Estimated cost:** $[15,000-30,000]
- **Deliverable:** Validated plan with reference implementation

### Phase 2: Incremental Migration (4-6 months)

- Module-by-module migration with biweekly deliverables
- Feature development continues at ~70% capacity
- Progress tracked across all 5 dimensions
- **Estimated cost:** $[primary budget]
- **Deliverable:** Fully modernized application, shipped incrementally

### Phase 3: Optimization (2-3 months)

- Performance optimization with modern Angular features
- Team training on new patterns and tooling
- AI development tooling configuration
- **Estimated cost:** $[secondary budget]
- **Deliverable:** Optimized application with trained team

### Total Migration Investment: **$_______**

## 4. Risk Mitigation

**Timeline risk:** The incremental approach delivers working software every two weeks. If the project is paused or cancelled at any point, all completed work remains in production.

**Capacity risk:** The 70/30 split between migration and feature work has been validated across enterprise migrations. Feature velocity dips slightly during migration but recovers and exceeds pre-migration levels within the first quarter after completion.

**Skill risk:** Phase 1 includes a pilot that surfaces skill gaps. Phase 3 includes structured training. The migration plan accounts for the learning curve.

## 5. ROI Summary

| Metric | Value |
|--------|-------|
| Annual cost of inaction | $_______ |
| Total migration investment | $_______ |
| Payback period | _______ months |
| 3-year net benefit | $_______ |
| Velocity improvement (estimated) | _______% |
| Hiring time reduction (estimated) | _______% |

---

## 6. Recommendation

Approve Phase 1 ($[cost], [timeline]) to produce the assessment data and pilot implementation needed to validate the full migration plan. Phase 1 results will provide the evidence to make a confident Phase 2 decision.
