Our advice
Observing and representing uses

You probably have very limited resources (time, people, equipment). Certain representation techniques can be very resource-intensive, such as film (time-consuming capturing and editing) or stop-motion animation (time-consuming post-processing). Bear in mind that it's not the quality of the representation that's crucial, but the message it delivers. For example, there's no point in creating an animated film at 24 frames per second to highlight the problems associated with elderly people falling! The main message is therefore to choose both a technique and a level of ambition relevant to what you want to show.
