In a situation where testing results conflict, what is the first step that should be taken?

In scenarios where testing results conflict, the best initial step is to initiate resolution testing. This approach allows for an objective and systematic way to gather additional data to clarify discrepancies. By conducting resolution testing, you can isolate specific variables and identify any underlying issues affecting the initial results. This step emphasizes the importance of empirical evidence in making informed decisions.

Conducting a review of all documentation and holding a meeting with stakeholders are important later steps in the process after resolving the immediate discrepancy through additional testing. These steps involve considering and discussing the broader context of the project, but they do not directly address the immediate need to clarify the conflicting results. Similarly, re-testing materials immediately may not provide the necessary insights into why the discrepancies occurred and might not follow a structured approach to data verification. Thus, initiating resolution testing is the most appropriate first action to correct or confirm testing outcomes.
