Software teams often need to decide where to use manual testing and where automation makes more sense.
Manual testing helps catch issues that depend on human judgment, such as usability gaps or unclear workflows. Automation testing is better suited for repeated validation, large test volumes, and ensuring consistency across builds.
This is rarely an either-or choice. Most teams use both. The key is knowing what to test manually, what to automate, and when to shift between the two as the product evolves.
