Attentive looking and systematic recording of people, artifacts, environments, events, behaviors, and interactions
Semi-structured observation typically describes ethnographic methods in the exploratory phase of design.
Ethnographic observations should be flexible, yet systematic, careful, and well documented with notes, sketches, photographs, or video.
Semi-structured observations are typically synthesized for guiding design inspiration, but content analysis may be performed to uncover themes or patterns.
Structured, or systematic observation, is formalized by pre-structure utilizing worksheets to track time intervals, behavioral categories, or counted successes and errors.
If sample sizes are large enough, results can be quantified for analysis otherwise, it is common to look for patterns or trends across observations.
Observations should differentiate between factual behaviors witnessed and inferences, speculating the meaning and motivations behind actions.
