So this week’s reading in UX book spends a whole chapter discussion prototyping. The reason of having prototyping as an essential method in product design according to the book is that a prototype gives you something to evaluate before you have to commit resources (time, energy, investment, etc) to build the real thing. There are four factors concerning prototyping: breadth, depth, fidelity, and level of interactivity. Different values of these four factors bring diversity to the types of prototyping. To determine how far you want to go in each factor, you must consider both the stage of progress and the design perspective. The author seems to be a strong advocate of paper prototyping. The book describes in length and detail how this method is use and the guidelines one must follow for it to be effective. Then it analyzes the pros and cons of paper prototyping. Finally, the book talks about the transition between prototype and product.
The reading has convinced me that prototyping is effective in discovering major issue from early stage. And I was also made to believe that paper prototyping has advantages over wireframe. Top of them all the advantages, the potential of paper prototyping is almost unlimited (if you don’t mind it’s only two dimensional). If combined with physical prototyping, it can cover 3 dimensional design as well. I just hope that we get a chance to do a prototyping exercise in this course. That will sure bring a lot of fun. However, on the other hand, the prototyping method described here in the UX shares lots of similarity to defining the interaction framework in Cooper’s book. Sketching and storyboarding are basically Cooper’s way of saying paper prototyping. Although UX book describes this book in much more details than cooper and offers a much broad concepts of prototyping, this method doesn’t not build on the foundation of personas, scenarios, and requirements. I think that’s probably the reason why it’s destined to fail and need multiple iteration to get right. If we do as Cooper says, build prototype on personas, scenarios and requirements, I think we can guarantee that we’re on the right track.
BTW, the links to additional readings on BB aren’t working…
It says “The specified resource was not found, or you do not have permission to access it.”
