I bring this answer from a lifetime of software development
so view it in that context. If you're building a car, look
to other responses for your answer.
Alpha testing is conducted by the development team. When a
product is bug free (enough) it is passed to a group of
willing end users who will perform Beta testing. When Beta
testing is revealing nothing significant in the way of new
bugs or change requests, an in-house product might go into
Pilot mode with a larger group of users before going on to
full Production. For an externally used product it will go
from Beta to Production.
In Alpha testing, "Bug free (enough)" can be determined by
the project managers as the Alpha testing progresses but
ideally, a limit should be set before Alpha begins. e.g.
When the Alpha test team is discovering fewer than 5 new
low level bugs in a week it is time to give the users
involved with Beta testing. There should be a similar bug
count limit on Beta testing. Live by the law of diminishing
returns,
I see three key events that must take place while
developing software... Stop designing and start coding.
Stop coding and start testing. Stop testing and start
using. It is too easy to get hooked up on the each of these
phases. You can design, code or test a product to death.
Recognize when it is time to move on. If you can’t get out
of one of these phases, you should look very closely at who
you have in the project team, chiefs and indians.
