Quality is objective. It is measurable. It can be seen, felt and measured. Teams working on testing of a product know well how to measure the testing effort and quality imbibed in the product. A straight measure of quality in a product is the encounter of bug in the product post its release. Multiple bugs detected by multiple users in live environment is definitely a disaster for the product. A straight question raised in such cases goes on the role of quality testing team and their efforts.
Test cases, test bed, testing efforts is all what counts in the measurement of testing in efforts to produce a bug free product to go live for end user and business environment. It is very important to engage test team members right since the inception stage of a project so as to avoid any confusion at a later stage that will definitely lead to time loss which is a big factor in a project. Projects do get delayed but the intelligence required to manage a project is to ensure delays caused by unnecessary and unwanted activities.
