About half a million years ago I sat through a Nolan Bushnell (Atari, Chuck E Cheese) speech.<p>He said a sentence that has stuck to me forever. "The only question that matters is when you say 'What is your Visa card number?'" Meaning that until the moment of truth when money leaves your customer's wallet, everything your prospective customer says is bullshit and not worthy of building a business on. He was completely dismissive of market surveys, etc. Waste of time and money.<p>He brought this thinking into physical products, too. His basic "build a business" model was:<p>1. Make a flyer. See if you can get an order. (Similar to the "dry test" idea). AKA the landing page.<p>2. Iterate until . . .<p>3. . . . you get nibbles and interest. Then make a mock-up. (You've gone from two dimensions to three dimensions).<p>4. Continue iteration on the marketing front until you get an order. (I.e., the customer gives you his/her Visa card).<p>5. Then and only then manufacture ONE of your products, even if it costs you $5,000. It's cheaper than manufacturing a bunch of units to get your unit cost down below $200.<p>6. Iterate based on experience, refine the product, get another order, etc. etc.<p>Even antique guys are smart. :-)<p>Sincere apologies to N. Bushnell if I mis-remember this. It was a long time ago. But the "What's your Visa card number?" question stuck. Life is either bullshit or jellybeans, and in business I tend to treat things as bullshit until a prospective customer puts his/her wallet on the line.<p>/Phil
