Here are 7 steps regarding effective Guerrilla usability testing:
1.) Come up with a list of all important tasks. For example, Facebook’s actions would be:
- Scroll through new posts
- Update your status
- Send a private message
- Upload a photo
- Add a friend
- Change your password
2.) Prioritize your tasks - it’s time to prioritize all items by giving points from 1 to 3 based on how frequently the tasks are performed.
Add: 3 points to tasks that most users will do most of the time, 2 points if they do it occasionally, 1 point if they only perform this task every once in awhile (like returning a product on an e-commerce site).
In the above example, prioritized:
- Scroll through new posts: 3
- Update your status: 2
- Send a private message: 1
- Upload a photo: 2
- Add a friend: 1
- Change your password: 1
3.) Turn your tasks into scenarios - As long as you get your scenario right, your testing will always work. And making good scenarios will help you test as if you had your target audience.
4.) Start Guerrilla testing - The secret of guerrilla usability testing is to approach people and ask them to test your site, app or prototype.
There’s no need to care about who you’re testing with, no need to worry about how to record the sessions, and thus you don’t need written permissions or anything else to get started.
5.) Capture Guerrilla testing Insights- Method #1: List top 3 usability problems
The most obvious way of capturing your findings is to simply list the top 3 usability problems identified in the tests. There’s no need to write down everything you find. Guerrilla testing is about finding and fixing the most severe problems, not agonizing over every possible obstacle a user might encounter.
Method #2: Capture task completion
A more sophisticated way of documenting your findings, is to capture the task completion for each of your participants. You can use the following designations:
- If a user can perform the task quickly and with no trouble, mark it a 3.
- If a user can perform the task but has some problems, mark it a 2.
- If a user couldn’t perform a task, mark it a 1.
6.) Fix your Usability Problems - Go for the biggest issue first and then focus on implementing quick fixes.
7.) Test again and make it a habit.
