I work for a small company (less than 200 employees) whose software group only makes up a small part of our staff (4 employees, occasionally with a few contractors).  The four of us have been making strides in transitioning to better practices, and one of the next logical steps is to improve our testing.As anyone who has done any meaningful tests knows, testing takes a lot of time - and at my company, it takes too much time to justify to management, so we generally do what little we do on the sly.  I don't think this is serving us well, as we keep coming up against otherwise avoidable problems when we ship under-tested software.I would like to be able to come to management with a justification for hiring a dedicated software test engineer (someone who can both write automated tests and perform manual ones).  Are there any good published studies that show the benefits of adding such a position to a small company?  Where can I find information about costs associated with the position?  I plan on doing a little number crunching on our own history, but having some external sources to point to would help bolster my case.
How can I justify software testing to management?
