Here’s an interesting historical anecdote from Karl Fogel’s Producing Open Source Software on the value of preparing for meetings.

In his multi-volume biography of Thomas Jefferson, Jefferson and His Time, Dumas Malone tells the story of how Jefferson handled the first meeting held to decide the organization of the future University of Virginia. The University had been Jefferson’s idea in the first place, but (as is the case everywhere, not just in open source projects) many other parties had climbed on board quickly, each with their own interests and agendas.

When they gathered at that first meeting to hash things out, Jefferson made sure to show up with meticulously prepared architectural drawings, detailed budgets for construction and operation, a proposed curriculum, and the names of specific faculty he wanted to import from Europe. No one else in the room was even remotely as prepared; the group essentially had to capitulate to Jefferson’s vision, and the University was eventually founded more or less in accordance with his plans.

The facts that construction went far over budget, and that many of his ideas did not, for various reasons, work out in the end, were all things Jefferson probably knew perfectly well would happen. His purpose was strategic: to show up at the meeting with something so substantive that everyone else would have to fall into the role of simply proposing modifications to it, so that the overall shape, and therefore schedule, of the project would be roughly as he wanted.
