Why do testers need root cause analysis?
Why do testers need root cause analysis? I understand what it is but can't fathom how to describe a connection. How does the definition of root cause analysis change in terms of QA?
When a defect happens, you want to analyse how it happend. So you can decide if you can prevent similar issues in the future. I would use a simple root-cause analysis for that. Maybe you want to involve other stakeholders like users, developers, managers, etc...
I think it is part of the QA role to make sure preventive actions happen, as we
are a force for continuous improvement, helping the team adapt and optimize in order to succeed, rather than providing a safety net to catch failures.
