I've mentored a few[hundred] in the past - but - my question to you today is ...
what does your test harness look like ?
do you have any formalized methodology for testing your app, or for testing components ???? Do you have a QA department or a 3rd party floating around to handle your testing ??

PS - due to time contraints - if your in the Pennsylvania area ? please - don't bother to reply.
