Prototyping improved my life in ways I never thought possible. Prototyping made me stronger and healthier than ever before. Prototyping saved me from a life of sin. Prototyping is how I met my wife. Prototyping: It's whats for dinner.

As you wouldn't let a new pilot take off without hours spent in a simulator, you shouldn't let your product process take off without a prototype.

We use prototypes for storytelling. For explaining app ideas to stakeholders. People have a nicer time when they are presented with a realistic model of an idea. They can use their thinking time to evaluate what you're showing them, rather than trying to make sense of it.

Nothing will ever elicit better feedback than prototypes – static mockups can't deliver an accurate enough experience of a product for users so that you can get the kind of insights you need to iterate to an optimal design.

Prototyping bridges the gap between design & development!

Just watched a great Google SPAN talk about this: https://www.youtube.com/watch?time_continue=1541&v=zhqc6VGurP8

Building a product without prototyping is like starting construction on a building without a blueprint. When you prototype, you give everyone on the team a solid understanding of how it's going to work so everyone can execute the project like it's supposed to be executed. Not to mention, you find the flaws in your design before hours of development are spent on them.

It's one of the quickest way to kill a bad idea. Spend a day or two to make a rough prototype (no polish and shit) and present it to one or a few customers. See why it fails and if it's not a basket case - improve and repeat.

You're not done until the customers are throwing money at you.

Prototyping has allowed us to quickly iterate on ideas, research user behavior, conduct usability testing, validate (or invalidate) assumptions before dedicating a lot of man hours to building something.

It saves money, time, and helps bring clarity.

Prototypes are the quickest and cheapest way to fail, and learn

Prototypes save businesses and development teams time and money by allowing designers to test interaction hypotheses before they go into development. It validates good ideas and exposes poor ideas.

In addition, in the context of a prototype being used to get buy-in from key stakeholders, a well-crafted one can generate excitement and act as a catalyst for action compared to a presentation of static screens.

A boring and obvious response, but I wanted to highlight the financial benefits of prototyping. Best of luck with your research!

Prototyping allows us to tell a cogent story to a group of people with various levels of engagement with a certain project. Nothing explains how something will work like seeing it work.
