When generative AI is the right solution โ and when it isn't. Real-world examples from financial services companies using AI on AWS.
Every successful GenAI project follows this cycle:
| Phase | What you do | Key question |
|---|---|---|
| 1. Define | Identify the use case and business problem | Is this a good fit for GenAI? |
| 2. Select | Choose the right foundation model | Which model fits the task, budget, and latency needs? |
| 3. Improve | Optimize performance (prompt engineering, RAG, fine-tuning) | Is the output quality good enough? |
| 4. Evaluate | Measure quality with rubrics and testing | How do we know it's working? |
| 5. Deploy | Put it into production with guardrails | Is it safe, compliant, and monitored? |
Generative AI excels when the task involves unstructured data, repetitive content creation, or personalization at scale.
| Category | Finance Use Case | Example |
|---|---|---|
| Content Creation | Reports, narratives, summaries | Auto-draft merchant risk assessments from transaction data โ structured GREEN/AMBER/RED reports in seconds |
| Personalization | Tailored financial communications | Generate personalized PayLater limit explanations, customized collection reminders based on customer history |
| Automation | Document processing at scale | Extract data from thousands of vendor invoices, classify and route customer complaints |
| Data Augmentation | Synthetic data for testing | Generate realistic test transaction data for new market launches without using real customer data |
| Creative Exploration | Ideation for process improvement | Brainstorm automation opportunities, draft policy change impact assessments |
| Localization | Multi-market content | Adapt compliance notices and internal policies across SG, MY, ID, TH, VN, PH |
Not every problem needs GenAI. These scenarios require different approaches:
| Scenario | Why Not | Better Approach |
|---|---|---|
| Real-time fraud scoring | Requires sub-millisecond deterministic decisions at massive scale | Traditional ML models (XGBoost, neural nets) |
| Interest rate calculations | Requires exact math, zero tolerance for approximation | Deterministic financial formulas |
| Regulatory capital calculations | Must be auditable, reproducible, and precisely calculated | Rule-based systems with audit trails |
| Credit scoring (final decision) | Regulatory requirements for explainability and fairness | Traditional ML with SHAP/LIME explainability |
| Transaction settlement matching | Exact matching logic, penny-accurate | Deterministic matching algorithms |
| AML final determinations | High-stakes regulatory decisions requiring human accountability | Rule-based detection + human investigation |
Here's how GenAI maps to the key finance processes your team manages:
