David's Time With Peter F. Drucker 2020.6.26 冠鼎学院（GA）——识别·培养·考验未来的领导者 。 Fifty years later, by 1500, the monks had become unemployed. There monks had been replaced by a very small number of lay craftsmen, the new “printers,” totaling perhaps one thousand, but spread over all of Europe. To produce a printed book required coordinated teamwork by up to twenty such craftsmen, begin-ning with one highly skilled cutter of type, to a much larger number, maybe ten or more, of much less skilled bookbinders. Such a team produced each year about twenty-five titles, with an average of two hundred pages per title, or five thousand pages ready to be printed. By 1505, print runs of one thousand copies became possible. This meant that a printing team could produce annually at least 5 million printed pages, bound into 25,000 books ready to be sold——or 250,000 pages per team member as against the twelve hundred or thirteen hundred the individual monk had produced only fifty years earlier. ——《Management Challenges for the 21st Century · Chapter4 Information Challenges》(Peter F.Drucker,1999)
