Collect feedback on your solution ideas
To test how effective your ideas really are, the best approach is to get direct input from your target group. Interviews are a great way to do this. With clear, focused questions, you can assess the potential, acceptance, and impact of your ideas—and gain valuable insights for further development. Follow these four steps
1. Choose the right interview partners
This step is key to getting meaningful results. Make sure to include a range of perspectives, backgrounds, and experiences. Alongside people from your target group, consider speaking with experts and others working in similar fields.
2. Create interview questions for your target group
The following question ideas are just a starting point – adapt them to fit your solution and your audience. Depending on the question, you can offer multiple-choice options, rating scales, or open-ended answers.
Evaluate the proposed solution
- What aspects of our solution do you like most?
- Are there any parts you find problematic or ineffective?
- How easy is our solution to understand and use?
- What suggestions do you have to improve our concept?
Relevance and acceptance of the solution
- How likely are you to use our solution?
- What would motivate you to actively use it?
- What might prevent you from using it?
Assessing potential impact
- To what extent do you agree that our solution could lead to positive change in your environment?
- What specific positive changes could our solution bring about?
Feasibility and resources
- How realistic do you think implementing our solution in your environment is?
- What challenges or barriers might arise?
- What resources or support would you need to use it successfully?
- Would you be able to use the solution on your own, or would you need help?
Cooperation and engagement
- How willing are you to actively contribute to improving and adapting our solution?
- What kind of support or collaboration could you offer to help us develop the solution further?
3. Write a clear, friendly invitation to the interview
Be transparent about what participants can expect. Many people will wonder if they need to prepare or how much time it will take. Explain the purpose of the interview, how long it will last, and make it clear that no preparation is needed. Thank them in advance for their time and emphasize how valuable their input is to the project.
4. Create a comfortable atmosphere
This is key to open, honest conversations. Start by briefly introducing yourselves and your project, and explain why you’re doing the interview. Make sure participants feel at ease – be friendly, keep the setting relaxed, and let them know they can ask questions or share concerns at any time.
