Section 4a — Putting Problems to the Test: Validation Methods
Multiple Methods for Stronger Validation
Since no single method gives us a complete picture, effective problem validation combines several approaches. Here are the key techniques you can use:
1. Problem Interviews
Conduct conversations with members of the community (potential users or customers) to understand their pain points. Ask open-ended questions that let them describe their experience in their own words.
Good interview questions:
- "Can you tell me about a time when you faced [the problem]?"
- "How does this affect your daily life?"
- "What have you tried to do about it?"
- "What would an ideal solution look like for you?"
2. Surveys
Surveys allow you to collect information from a larger group of people at once. They are useful for seeing patterns across many responses.
Tips for good surveys:
- Keep questions clear and simple
- Mix multiple-choice questions (for easy analysis) with open-ended questions (for deeper insight)
- Avoid leading questions that hint at the "right" answer
3. Observation
Sometimes the best research is simply watching and taking careful notes. Observe the community in context — how do they actually behave? What workarounds have they created? What frustrations can you see directly?
Observation captures what people do — which sometimes differs from what they say.
4. Market Research
Look at existing reports, articles, and data related to your problem area. Has this problem been documented? Are there statistics that show how widespread it is? What solutions have been tried elsewhere?
This kind of secondary research gives your project credibility and helps you understand the bigger picture.
