Beta is the software development phase following alpha (beta is the second letter of the ancient Greek alphabet, used as the number 2. It is not nowadays usual to speak of a later gamma test). It generally begins when the software is feature complete. The focus of beta testing is reducing impacts to users, often incorporating usability testing. The process of delivering a beta version to the users is called beta release and this is typically the first time that the software is available outside of the organization that developed it.
The users of a beta version are called beta testers. They are usually customers or prospective customers of the organization that develops the software, willing to test the software without charge, often receiving the final software free of charge or for a reduced price.
Beta version software is often useful for demonstrations and previews within an organisation and to prospective customers. Some developers refer to this stage as a preview, prototype, technical preview (TP), or early access.
