Chapter Five. Developing the Design > Vision Clips/Sample Calls

Vision Clips/Sample Calls

As an alternative—or an enhancement—to a call flow diagram, the designer may want to create a vision clip to describe how the application will work. This is a sample script that illustrates a vision of how the final version of the system might sound. (Not to be confused with a sample call, which typically refers to a recording of an actual exchange from a live system.) The clip is produced as an audio file, complete with sound effects or music. For many designers, a vision clip is a very easy place to start the creative process, because before they start drawing boxes and arrows on paper, they can quickly sketch out the sound—and feel—of the system and show and play it to other people for quick review.

Sharing a vision clip with a client is a great way for designers to initiate a discussion of their design ideas. But it's important to remind clients that the vision clip is only a rough draft and subject to change. A vision clip can also help jump-start the process of structuring the overall call flow.
