When you want to see how well a prototype works, there are some important things you should look at. These things, called metrics, help you improve your design and make the user's experience better. Here’s a simple breakdown of the key metrics:
This one is easy to understand. It shows how many people are able to finish tasks correctly. For example, if you have 10 users and 8 of them do the task right, your success rate is 80%. This tells you how easy it is for users to figure out your prototype.
Another important part to think about is how long users take to finish tasks. If they finish quickly, that usually means the design is good. But be careful! If they finish too fast, it might mean they aren’t really paying attention. Measuring the average time helps you compare it to what you expect.
This metric looks at how many mistakes users make while using your prototype. Mistakes can be things like clicking the wrong button or not understanding what to do. If you see a lot of errors, it likely means something in your design is confusing.
The SUS is a quick questionnaire that helps measure how usable your design is. It has 10 statements about usability, and users score their agreement from 1 to 5. The final score shows how happy users are and helps you compare different prototypes.
Numbers are helpful, but don’t forget about comments from users! Asking open-ended questions or having chats can show you the reasons behind users’ feelings. Their feedback can highlight problems and places where you can get better that numbers alone might miss.
Using these metrics together gives you a complete picture of how well your prototype works. It’s about looking at both the numbers and the user comments to understand everything better. Keep using what you learn to improve your designs, and you'll see great changes!
