The Testing and Quality Factory prevents you from waiting for the Release to test delivery. This wait usually has an efficiency below 50% in the identification of defects. With the hiring of the Factory of Tests and Quality you will have a true Certification Center and start to have a monitoring of the development, which increases this efficiency to above 95%.
There are defects only identified when software failures arise many months after the approval of the delivery or at critical times; for example, when services start to mesh or at the end of the warranty. Often, the cause is coding or architecture problems. The Test Factory works to protect you from this situation.
The hiring of the Test Factory prevents the business area from doing the role of tester when homologating the user's acceptance. You might think you're already paying the Software Factory to do this. And you're right in many cases. But what about cases where a defect can critically compromise your outcome and reputation?
