Prototypes are becoming a design deliverable with the advent of many sophisticated software applications spurred by Rapid Prototyping, 3D Modeling etc. However, the initial paper sketch is arguably the best tool, at least in the beginning. Prototyping helps us to design better user experiences. However, many of us still forget to include the user! We still dwell on what we can do versus looking at what the user does! Even at the paper stage of prototyping, I encourage you to try to articulate that feeling and function of the design into a model and put it in the hands of the user. Their interactivity is the most meaningful part of design. Do it early and do it often.

Making Effective Prototypes
In order to evaluate a prototyping tool or technique, we first need to define what makes an effective prototype. The best prototypes are ones that slipstream right into our design process. We want the ability to quickly take sketches from a whiteboard to something interactive.
Effective prototypes are fast. We want to use techniques that allow for rapid iteration. A prototype should not just be bolted onto the end of a design process. Incorporating the creation of a prototype into your daily design work allows new ideas to emerge and validates concepts quickly.
Effective prototypes are disposable. Just like with any design deliverable, we are creating an artifact intended to express an idea to someone else (stakeholder, developer, user, etc). Once that design idea has been communicated, the prototype deliverable can be discarded. We don’t have to feel the burden of creating a masterpiece that will live on, and we certainly don’t have to work in production-level code.
Effective prototypes are focused. We want to select the interactions of our design that really need to be prototyped. Look for the parts of your design that have of complexity. Look for interaction patterns repeated throughout the user’s experience. Look for the interactions that bring revenue to your product. A prototype that demonstrates these interactions will be the best use of your time and energy.
An informative presentations on prototyping is from Jonathan Arnowitz who happens to be one of the authors of Effective Prototyping with Excel. In the book, the authors discuss how to use use Excel skills to create prototypes especially for wire frames. It is interesting how such a common and widely owned tool can offer such a wide array of solutions. The presentation below labors on wireframes at the beginning but the message soon turns into applicable information for all.
