You have candidate sounds and no idea whether they are any good. But “any good” is not one question. Whether people like a sound, whether they understand it, and whether they can tell it apart from your other sounds are three different things, and each needs a different kind of test. Decide which questions you actually need to answer, then work through the panels. What comes out is a test plan: what you are going to find out, and what decision each finding supports.
“Is it any good?” cannot be measured, because it is several separate questions wearing one coat. Each of the eight below can be measured, and each needs its own kind of test. Tap any of them and mark the ones you need — those become your measurement plan, and each one names the method that answers it.
A question bank can only return what you already thought to look for. This deals you a situation instead, and lets you work out what you would need to know about it.
Assembled from what you chose and kept. Each outcome names the family of methods that can measure it; chapter 6 covers how to run those methods.
