I have stated my affection for Steven Blank's Four Steps to the Epiphany
several times on this blog and came across a couple of items relevant to it today via Venture Hacks.  The first is a rather lengthy Powerpoint presentation embedded below that walks through the methodology and process laid out in the book.

As I have said previously, this book is now required reading for my team members because I believe it lays out the challenge and steps for conceptualizing, building, and launching a successful product as an early stage company.

Focus on the customer, iterate often, and be prepared to have your assumptions be wrong are among the key takeaways.
