When it comes to conducting a thorough interview or investigation, it's important to have a well-defined "line of questioning" in mind. But what if you're tired of using the same old phrase over and over again? There are plenty of other synonyms that can be used to describe this process. For instance, you might refer to your "approach," "angle," or "methodology" for asking questions and gathering information. Other options might include "inquiry," "interrogation," or "cross-examination". No matter what term you use to describe it, the key is to have a clear and focused strategy for getting to the heart of the matter.
