It takes time to find and create bugs - the focus should always be quality, never quantity. Thank you for pointing out that I didn't explain myself clearly. For now I am sure that it is not. Thanks for your oppinions. Huge thanks to Traisee.
Managers are really very different guys, but they are Managers.
Unfortunately, QA doesn't work like that. Please accept the above comments as reasoning for your manager to change his measurement tactics. There isn't a magic number to reach each day, only a higher level of quality than when the day began The size, complexity and requirements of the product should dictate the resources needed on a project. If they are truly using it as a measuring stick, then an education process needs to happen here. Or better, if there is a bonus awarded for every defect found, maybe you should consider striking a deal with the developers.
