For generations there is a fundamentally ongoing fight between the product team and the quality team of any project. This is a generic fight for which there has not been a solution found so far. The fight is as below.
Product manager and his team always think that their product is fantastically built as per customer requirement with 100% requirements business needs met while building it. And the product is bug free. They further have a mindset that the product when goes to quality for internal testing on a test bed similar to live environment, the testing team takes extra long time with an intention of overstretching the whole exercise of testing just to maintain their importance intact.
According to product team 90% of the bugs are either unnecessarily listed to build the test report long with large number of bug findings or the similar kind of bugs are repeated for the same purpose.
