# QA engineer in Agile team / Shift left testing

> I try to be involved from the beginning of the development process.
> \
> I participate in refinement and planning, clarify acceptance criteria, identify risks early, prepare test scenarios and then validate the implementation through different levels of testing.

## Shift-left testing

**Shift-left testing** means **moving testing activities earlier in the software development lifecycle**, instead of waiting until development is finished.

Requirements → Design → Development → Testing → Production

QA involved earlier

The idea is: **find defects as early as possible**, because they are usually cheaper and easier to fix early.
