Using 6 Page and 2 Page Documents To Make Organizational Decisions
Ian Nowland has written up the Amazon 6-pager strategy:
A challenge of organizations is the aggregation of local information to a point where a globally optimal decision can be made in a way all stakeholders have seen their feedback heard and so can “disagree and commit" on the result. This document describes the “6 pager” and “2 pager” document and review meeting process, as a mechanism to address this challenge, as practiced by the document’s author in his time in the EC2 team at Amazon, and then at Two Sigma.

[...] The major variant I have also seen is 2 pages with 30 minute review; when the decision is smaller in terms of stakeholders, options or impact. That being said, there is nothing magical about 2 pages, i.e., a 3 page document is fine, it just should be expected to take more than 30 minutes to review.

Volkswagen emissions cheating was technical debt
Is this the first case of tech debt costing $18 billion?
"Perhaps the engineers told themselves that the cheat was a stopgap, and they’d address it later. If so, they didn’t."

How Irish Navy’s expertise saved 367 from 30-second sinking in Mediterranean
War-game exercises saved the day:
As the Ribs made their assessment of the situation and began reassuring those on board that help was at hand, the hopelessly overloaded vessel suddenly listed and sank. The sinking took just over 30 seconds. In those 30 seconds, the Captain of the LE Niamh took a number of instant command decisions that saved hundreds of lives. Most of the refugees cannot swim. Their life expectancy in the water would be measured in seconds.
The crew of the Ribs immediately began throwing orange lifejackets into the water – encouraging the now frenzied and milling survivors to cling to them. Individuals, then groups clung to the lifejackets – and one another – as the Ribs rallied around trying to keep the floating human mass from dispersal into wider waters and almost certain death.
In the meantime, the commander of the LE Niamh managed to manoeuvre close in to the survivors where spare life-rafts were launched into the water. These 25-man inflatable life-rafts were specifically ordered and kept on board the LE Niamh following a “war-gaming” exercise, where the officers and crew envisaged such a nightmare scenario. Had this forward planning not taken place – there would have been no such extra inflatable lifeboats on board.
