I haven’t seen prototyping represented this way before – it’s a neat model. Taken from Prototyping – A Practitioner’s Guide by Todd Zaki Warfel
Practice makes perfect. Champion sports teams practice constantly. Zen masters will tell you that the only way to achieve enlightenment is practice. Practice is at the very root of learning. As you practice, you learn, and as you learn, you improve.
When you prototype, you allow your design, product, or service to practice being itself. And as its maker, you learn more about your designs in this way than you ever could in any other way.
So make prototypes and break them, test them and learn from them, model your ideas when they are still in their infancy, and continue to make and break them throughout the design process. Trial and error and continuous re nement—this is the way we learn as children and continue to learn as adults.
And let’s not forget this: Prototyping is fun! It’s a playful, social way to develop your ideas. It’s in direct opposition to “design in a vacuum” or “design in an ivory tower.” It’s design with and for people. It’s play. And play, like practice, is a learning activity. Play is a rehearsal for life.
