How did we recover from the catastrophe? First, we classified our 503 customers into groups, according to the nature and size of the hardware configurations which they had bought... We assigned to each group of customers a small team of programmers and told the team leader to visit the customers to find out what they wanted; to select the easiest request to fulfill, and to make plans (but no promises) to implement it. In no case would we consider a request for a feature that would take more than three months to implement and deliver. The project leader would then have to convince me that the customers’ request was reasonable, that the design of the new feature was appropriate, and that the plans and schedules for implementation were realistic. Above all, I did not allow anything to be done which I did not myself understand. It worked! The software requested began to be delivered on the promised dates. With an increase in our confidence and that of our customers, we were able to undertake fulfilling slightly more ambitious requests. Within a year we had recovered from the disaster. Within two years, we even had some moderately satisfied customers.

“What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline? My answer to these questions is simple—it is the art of programming a computer.”

— Tony Hoare Primary source“At Harvard Business School, the great quantitative thing that bonds the first-year class together is what they call decision tree theory. All they do is take high school algebra and apply it to real-life problems. And the students love it. They’re amazed to find that high school algebra works in life.”
— Charlie Munger Primary source“I desire that there may be as many different persons in the world as possible; but I would have each one be very careful to find out and pursue his own way, and not his father’s or his mother’s or his neighbor’s instead. The youth may build or plant or sail, only let him not be hindered from doing that which he tells me he would like to do.”
