Is Understanding System Architecture a Must-Have Skill for QA Engineers?

Imagine working on a multi-vendor project where:

- Vendor A owns the frontend.
- Vendor B owns the backend APIs.
- Vendor C manages third-party integrations.
- Vendor D handles infrastructure.
- Your QA team is responsible for ensuring the entire system works seamlessly.

Each vendor claims their component is working as expected, but the end-to-end business workflow keeps failing.

Here's the question: Who identifies the gap, and how do we find it? 🤔

This is where understanding system architecture and system design can make a real difference. Let's brainstorm!

1️⃣ How important is system architecture knowledge for a QA Engineer or SDET? Is it a must-have skill or a nice-to-have?

2️⃣ In a multi-vendor environment, how can QA identify integration gaps when every vendor owns a different component?

3️⃣ Should QA be involved in architecture and design discussions from day one, or only after development is complete?

4️⃣ How do you approach testing when the failure occurs between two components owned by different vendors?

5️⃣ What techniques, tools, or strategies have helped you identify issues that component-level testing missed?

Your turn!

Share a real-world experience, a challenging scenario, or a strategy that worked for your team.

Let's go beyond test cases and explore how QA can contribute to building reliable systems - not just validating individual features.
