Surely you've heard of Ramit Sethi (this guy: http://www.iwillteachyoutoberich.com/ ). In one of his courses, he teaches how to model an idea and test it for profitability before implementing it. I'm pretty sure there's nothing new under the sun, and that some entrepreneurs somewhere have done this before. Can anyone provide me with a bullet point list, outlining the steps you would take to model a given idea and test it for profitability?
Thanks
