Sheet 18 - Evaluation through testing & interviews
To fully evaluate the effectiveness of the product, testing and interviews are required.
- Construct and carry out an interview with a potential user of the product. Let them handle the product and, if possible, use the product. Ask them about their experiences. Ask the user for ideas for further improvements.
- Construct and carry out an interview with any relevant experts, again asking for their opinions and thoughts about improvements.
Include photos and sketches (e.g. photos of the interviews taking place; sketches of potential improvements as suggested in the interviews).
