The following lists, in no particular order, the major players and what they do. The most common names are given, but expect variations and additions:

·         Testers or QA (Quality Assurance) Staff are responsible for finding and reporting problems in the software product. They work very closely with all members of the team as they develop and run their tests, and report the problems they find.

As you can see, several groups of people contribute to a software product. On large teams there may be dozens or hundreds working together. To successfully communicate and organize their approach, they need a plan, a method for getting from point A to point B.
