About leadership and organizational culture
The Abilene Paradox and Other Meditations on Management, by Jerry B. Harvey Very useful parables on management. Includes a great story about Captain Kohei Asoh, a Japan Airlines pilot who in 1968 landed a DC-8 in the San Francisco Bay and afterwards famously told investigators that he had just “fucked up” – an admission Harvey popularized as the Asoh defense, and used to celebrate the importance of truth-telling, mistake-revealing, and mistake-forgiving.
Organizational Culture and Leadership, by Edgar Schein Back in 1966, Edgar Schein invented the phrase corporate culture. This is the definitive guide to understanding and managing the culture of an organization.
Parkinson’s Law and other Studies in Administration, by C. Northcote Parkinson From 1957, Parkinson’s Law is best-known for the essay “High Finance or the Point of Vanishing Interest,” AKA the bikeshed essay. In 1999 Poul-Henning Kamp famously said on a FreeBSD mailing list that “I wish we could reduce the amount of noise in our lists and I wish we could let people build a bike shed every so often, and I don’t really care what colour they paint it.”

I added it to this page to placate Gerard Meijssen, a great Wikimedian who I believe is making fun of me in this post. In case you’re curious, it was Daniel Phelps who categorized the books under the Dewey Decimal system. I did the same once with my home library, so I was both charmed and horrified to watch that happen.
 I’m not a Quaker; I just find their consensus decisionmaking practices interesting.
