quality assurance (QA)

Word Categories

Actions undertaken to ensure that a product is fit for its purpose and free of mistakes.

In the context of e-book production, QA refers to manual and automated tests performed on the e-book file to make sure it is free of errors and problems.

For example, an automated QA program might check that the chapter names in the Table of Contents match the text of the actual chapter headings. Meanwhile, a worker might scan the book page-by-page to ensure that the book formatting is appearing as expected.
