What term describes a method or style used in business analysis tasks?

The term that best describes a method or style used in business analysis tasks is "technique." In the context of business analysis, techniques are specific approaches that practitioners use to perform various tasks such as eliciting requirements, analyzing data, or facilitating discussions. Techniques can include a range of activities, such as interviews, workshops, surveys, and modeling, which help analysts gather and understand information effectively.

While "protocol," "strategy," and "plan" may also relate to business analysis, they do not specifically denote the hands-on methods utilized for completing analysis tasks. A protocol typically refers to a set of guidelines or rules to follow but does not imply a particular execution style. A strategy pertains to a broader approach or overarching goals and how to achieve them, while a plan outlines specific actions to reach those goals. None of these capture the essence of the practical methods or styles that define the techniques used in the field.
