🧪 Proof of Concept (POC)
Definition:
A Proof of Concept (POC) is a small, quick experiment or prototype created to validate whether an idea, approach, or technology is feasible before committing large resources to it.
1️⃣ Why Do We Need a POC?
- To test feasibility of a new idea/tech.
- To reduce risk before large investment.
- To get stakeholder confidence.
- To uncover challenges early.
2️⃣ Characteristics of a POC
- Small scope → Not a full product.
- Time-boxed → Done quickly (days or weeks).
- Focused → Proves one specific thing.
- Throwaway code → Not production-ready.
3️⃣ POC vs Prototype vs MVP
| Term | Purpose | Scope | Quality |
|---|---|---|---|
| POC | Prove feasibility of idea | Very limited | Quick, experimental |
| Prototype | Show how it works (UI/UX, flow) | Wider than POC | Visual, but not production code |
| MVP | Deliver minimum usable product to users | Production-ready subset | Good enough to release |
4️⃣ Example Scenarios
- Tech Validation: Can Redis handle 1M writes/sec for our use case?
- Integration Check: Can our system connect with PayPal API smoothly?
- Algorithm Feasibility: Does this ML model detect fraud with 90% accuracy?
- Business Idea Validation: Will people actually use a “voice-driven grocery ordering app”?
5️⃣ POC Flow
Idea → Identify Risky Assumption → Build Small Test → Validate Result → Decide (Proceed / Change / Drop)
6️⃣ Analogy
Think of a POC like tasting a spoonful of food while cooking:
- You’re not serving the whole meal yet.
- Just checking if the recipe works before you invest time in cooking the full dish.
✅ Key takeaway: A POC is not about delivering a product; it’s about validating feasibility to make informed decisions.
