Before the test:
1. Set goals
Before you start planning the test, think about why you are testing. Write down what you want to find out. Then write down your wanted outcome. How do you expect your product or solution to work?
2. Pick your users
Decide what target group(s) you are testing and determine the number of testers in each group. A minimum of 5 people in total is recommended. But if you are testing multiple user groups, make sure you are testing 2-5 people from each user group. Remember: Don’t test on people you know.
3. Make a test plan
Plan the logistics such as time, location and tools needed, then write an introduction so everyone gets the same information. Define the criteria for passing the test (tasks completed, number of clicks, time to complete, satisfaction etc.). Remember: performance and satisfaction are different usability metrics.
4. Make an observation form
Invite your team to observe the tests and make them take notes in the same form. Give them information about the task, its reason, and the criteria for passing. Make sure they all observe more than one test.
5. Test the test
User testing takes time and planning, so don’t waste your first tester on a flawed test. Checking your introduction and questions will ensure it is understandable, takes the wanted amount of time and answers your goals.
