One thing that I don’t touch on in the presentation is the variety of prototypes that could be constructed, the talk only covers paper prototyping, and, particularly, not wireframes, low and high fidelity prototypes. Each has its own advantages, probably the subject of another post if asked about in the comments.
While paper provides significant examples, particularly for encouraging participatory design, at Hedtek we have moved on from paper protyping, preferring to deliver working code and UIs as part of our agile practices. Hey, different stokes for different folks! We are lucky enough to have skilled developers who can modify delivered functionality and user interfaces to order.
But this agile practice is not always the case, recently I’ve been sketching and, through sketches, exploring interfaces with one of our clients who wants to break new ground in computer-supported decision making.
