A good research question has a few components:
1. It is centered around understanding or discovering something new about people, not your product. We can often feel our product is the sun and people's lives revolve around it. But our products are just a tiny part of people's lives. A good research question looks at understanding something about people rather than just about products.
2. It is a problem or idea we don't fully understand. I've seen a few situations where research was done as a check-box exercise rather than for the right reasons. Ensure the research question addresses a knowledge gap or hasn't been done before.
3. It is about a concept or idea we need more information to move forward. Like above, we want to ensure our research question will help us gather the information that enables us to move forward with an idea or make a better decision.
