Before content is deployed to the user community, it should undergo a QA review. It should be tested for the accuracy of the information, to make sure that the topics play correctly in each mode; hidden frames and bubbles function correctly; items such as web pages, packages, see also links, jump-in points, and alternatives are in the right place and launch correctly; and sound, if included, possesses clarity and consistent sound levels. While much of this can be done using the Developer, it is a good idea to publish it to a Player environment and have a small group of users test it.
