Go and plan to manufacture 120 variants of something, then arrange shipping to 25 countries, announce the product on a day, start taking pre-orders 7 days later (and any manufacturing up to this point you just have to try and guess what people want), then ship so that customers - globally - start having it in their hands 7 days after that.
You can stockpile for longer before hand if you wish, but that will cost you mega bucks as you'll need more raw materials, more capacity of warehouses (raw materials, completed products), more shipping capacity, your retailers will need more capacity and couriers in the countries you're launching to will need more capacity.... Of course, that's making a huge (and probably incorrect) assumption that you could do all that for the number of people that want your product. The more you stockpile, the more people you also need to let go and put out of work sooner.....
Alternatively, you can hold off launching to some countries just yet. That's gonna cost your reputation though and people will whinge about it constantly as they really want your product.
Once you've done all that though, come back and tell us how Apple have screwed up their product launch better than everyone else, and that we shouldn't excuse them for their crap....
What is WRONG with Apple? How can the most valuable technology company in the world screw up a product launch better than nobody else? Every year we excuse them for their crap but it's always the same, they always get it wrong! Where is all this stock?!
