jm“Status quo bias is a little bit different, it’s quite fascinating actually. It sounds like a fancy piece of academic language to say that people don’t like change, and there’s a bit of truth in that, but it’s more subtle than that, he said.
“It’s like this — if you say to somebody ‘We’re going to change the way your town is laid out, we’re going to make it more friendly for pedestrians and cyclists,’ let’s say and you say there’s a plan to do it. A lot of people instinctually resist that. Actually, these sorts of policies are typically fairly popular but there’s a substantial minority who will really quite resist it,” he said.
Lunn said: “If instead of telling them that it is a plan you say ‘oh, there is this town that has this layout, do you like it or not?’, you get completely different responses. It is as if when something is a plan for change we instinctually, psychologically react to it more negatively.”
He said that if somebody else is proposing a plan some people will look for the negatives while they are less likely to do so if they are being asked a question in a more open way.

jmI’ve used the term *Feature Factory *at a couple conference talks over the past two years. I started using the term when a software developer friend complained that he was “just sitting in the factory, cranking out features, and sending them down the line.”

https://medium.com/@inowland/using-6-page-and-2-page-documents-to-make-organizational-decisions-3216badde909
jmA 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.

jmThe square root staffing law is a rule of thumb derived from queueing theory, useful for getting an estimate of the capacity you might need to serve an increased amount of traffic.

jmAs 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.
