Nobody likes bugs. Not the developers who accidentally write them, not the testers who hunt them down, and certainly not the users who stumble into them. But here’s the kicker — according to IBM, 5 to 30% of software defects still slip into production, costing companies up to 30 times more to fix post-release than if caught early.
The statistic highlights the essential nature of discovering software defects at the earliest point in development. Testing processes must shift left in development lifecycles according to the shifting left concept.
