Notes on Four Steps to the Epiphany

The Hero's Journey

A startup is not unlike a hero's journey; there's a vision or goal, and a journey filled with obstacles. Just as the hero's story has archetypal patterns, successful startups share the same outline. I.e., there is a true and repeatable path that eliminates or mitigates the most egregious risks and allows the company to grow into a large, successful enterprise. Not only that, but the successful path is nearly completely different from traditional "Product Development" processes and methodologies; Steve Blank calls this path "Customer Development". This book describes the "Customer Development" model.

Winners and Losers

Essentially, the criteria for success is simple: products developed with constant contact with customers win; products that aren't, lose.

Creating the Tip Calculator

Before you get started, download XCode 6 from the Mac App Store. You can buy an iOS Developer Program for $99, but it's not required at this stage.

Start reading about Objective-C. Here's a good quick overview. A more complete primer from Apple is here. If you prefer to learn by video, Lynda has a good overview, it's about 6 hours.

Follow the tip calculator video walkthrough to get the basic tip calculator functionality. After you finish the walkthrough, follow the hints below to add a settings page.
