Observation is a technique that involves watching how people perform their tasks and activities in their natural work environment. Observation can be used to gain an objective, first-hand insight into tasks and activities that are difficult to describe, as it allows the business analyst to see the actual behavior, interactions, processes, and problems of the users or customers. Observation can also help to identify the implicit, hidden, or unspoken needs and expectations of the users or customers, as well as to validate the information obtained from other elicitation techniques. Observation can be done in two ways: passive or active. Passive observation means that the business analyst does not interfere or participate in the tasks and activities, but only records and analyzes what is observed. Active observation means that the business analyst interacts with the users or customers, asks questions, and provides feedback during the observation.
