Takeaway Points

• Do one test with one (different!) user each week. This makes it easy to schedule testers, and you can iterate quickly.

• Use one of the test types explained in this chapter, or combine them. It’s often a good idea to let users play around with your product on their own, see how they do with it, and then move to a task-based test.

• Always end tests on a positive note.

• Use common sense when evaluating test results. Find the most pressing issues, fix them, and test again.

• If you are unsure about how widespread a problem is, simply postpone its resolution; since you will do another test soon, the problem will come up again at some point if it is important.
