Observation as a Requirements Gathering Technique in Business Analysis Observation is a critical technique used by Business Analysts (BAs) to gather requirements by closely watching how users interact with a system, process, or product in their actual work environment. It helps in uncovering implicit requirements, inefficiencies, and user behaviors that may not be explicitly mentioned during interviews or surveys. Types of Observation There are three primary types of observation techniques used in business analysis: Active (Participatory) Observation The BA directly participates in the process or workflow being studied. Provides a hands-on experience of the challenges faced by users. Useful for understanding complex workflows and real-time decision-making. Passive (Non-Participatory) Observation The BA watches users perform their tasks without interference. Ensures that the natural workflow remains unaffected by external influence. Helps in identifying gaps between documented p...
