What might be the most appropriate test technique to use after changing the risk mitigation approach?

Exploratory Testing is a highly adaptable technique that allows testers to investigate and evaluate a system's behavior without predefined test cases. After changing the risk mitigation approach, it becomes essential to explore new areas of the application that might be impacted by these changes.

This testing method fosters an environment where testers can use their creativity and intuition to uncover defects that might not have been anticipated in a structured or scripted testing approach. It enables the identification of potential issues that arise from the new risk management strategy and covers areas that have not been explicitly defined in requirements or test cases.

Moreover, exploratory testing is well-suited for situations where the implications of changes are not fully understood, making it a practical choice following any alterations in risk mitigation. Testers can also incorporate feedback dynamically by adapting their focus based on findings during the testing session, thus providing valuable insights into the quality of the system post-change.
