Have you ever wondered what the word “beta” really means? It seems in recent months I visit at least 20 sites a month that have a beta symbol. Though many people visiting this site already know what this term mean there are those of us that are still a little fuzzy about the meaning. I found a great explanation of the term on Ask Leo!

“Beta” is “?” the second letter of the Greek alphabet, after Alpha (?).

When used to refer to software, “Beta” is short for “Beta-test” - a period where the software is technically “feature complete” - meaning no new features will be added - and presumably stable enough for most common usages to actually work. (Contrast with “Alpha Test” which happens earlier, and is often not feature complete and even more unstable.)

But note carefully: it’s a Beta test - hence it’s “Beta software”. By definition Beta software is not finished and is known to have bugs, perhaps even serious ones.

Many Beta tests are private, invitation only. The number of users is kept controlled so as to be able to more efficiently control the quality of feedback and to handle the quantity. A private Beta test almost always includes specific instructions for reporting bugs, and getting support.

During a private Beta, “normal” support channels are not used, and will often have no clue as to the specifics of the Beta software.

A “public Beta” is nothing more than the incomplete Beta software released to the public for further testing. Feedback from real-world usage is often very valuable for identifying problems that need to be resolved before the product is finally released. You’ll often see a flurry of announcements in the press when a major product goes into public Beta, because then anyone can use it and try it out.
