Defect Leakage is natural. It’s common. If you build a software, bugs will be there. Similarly even if you Test a software, you cannot prove their absence. But we can do our best to eliminate maximum of them. Typically in most of the projects even if you complete functional testing (system testing) without any time & cost constraints, still UAT team (Business) manages to catch some more bugs. Any idea why? There has to be something missing in the system test coverage. What is it?
Today most of the organizations are moving or have already moved to agile development and testing. Or at least they think so. Sprints and daily stand-ups are common. Everybody is talking about Scrum & minimum viable product. We are tracking the team velocity & burndown. We have cut down on the documentation & invested in working software. Everyone is focused on customer satisfaction by accepting change. But wait a minute! This is too-happy a picture to be true.
