If you've ever tried to prepare and serve a beloved family recipe for a large group -- say 25 people or more -- you've experienced the fundamental problem of system scalability. Processes and facilities that work fine at one level break down totally when the quantities are multiplied by 5 or 10 times. Ingredients don't mix properly, your pans or oven may be too small, cook times vary, and even if all goes well in the kitchen, the dish may be cold by the time it is served to most of the guests.
