As you probably have already guessed, or already know, there are several tools available for creating wireframes when laying out your application, such as Balsamiq Mockups, Mockflow, and Visio. For my web applications, and in this book, my preference is to use Balsamiq Mockups. Which one you end up using for your applications, or are already using, doesn't matter. In fact, even if your wireframes are drawn by hand using a pen on the back of your napkin from your favorite fast food restaurant, it would be cool with me. Seriously, the important thing is that you get into the habit of creating wireframes before writing a single line of code. Why? Because it's a smart thing to do, and it saves you a lot of time. Additionally, it gives you the perfect opportunity to really think about what you're going to be building. And, it's something that you can present to users in order to get their feedback on the usability without writing a single line of code. There are even more benefits; it gives you some idea on how you would design your data model for the application, as well as APIs for services it may consume. Would you start a business without a business plan? Would you build your dream home without a blueprint? Building a web application shouldn't be any different specification out the pages using wireframes. Always. Capiche?
