There are lots of books about software testing. The books I know focus on - how developers can test their own software with unit tests and other methods - how to improve the software with usability tests.
In addition it is sometimes helpful to let non-developers test the software for bugs, because hired part-time temp workers are cheaper than developers.
Are there any books that focus on this part of software testing? I'm imagine chapters on how to find good testers, how to instruct them, how to decide what they should test, how to sort and record the bugs they found etc.
Can anybody recommend such a book?
