The agile methodology focuses on building in quality from the very beginning of the software lifecycle. That is why we aim to find and fix defects early on: A defect found and fixed in an earlier lifecycle phase is a multitude cheaper than the same defect at a later stage.
But how can we more easily make it possible to prevent defects from percolating deeper in the software development lifecycle by fixing them in their nascent stages?
This is the main theme of my latest article for @Gurock TestRail blog – where I explore and explain ways to foresee, analyze and thwart defects in an agile context.
A hardening sprint is an additional sprint that some teams run to stabilize the code and ensure that everything is ready just before release. Agile teams vary in their opinions on using hardening sprints in Scrum, but if your team does agree on having one before your release, there may be a lot to be done and varied expectations from the product owner, testers and developers. It may also lead to other work being delayed, leading to accumulation of technical debt.
