Many of you have seen the famous Westrum Organizational Typology model, so prominently featured in State of DevOps Research, Accelerate, DevOps Handbook, etc.

This model was created Dr. Ron Westrum, a widely-cited sociologist who studied the impact of culture on safety

 Thanks to Dr. @nicolefv, I was able to interview him for an upcoming episode of the Idealcast! 🤯

It was a very heady experience, and while preparing to interview him, I was startled to discover how much work he's done in healthcare, aviation, spaceflight, but also innovation.
@nicolefv I've read 4+ of his papers, so I thought I was familiar with his work. (Here's one paper: https://t.co/7X00O67VgS)

I was startled to learn he has also studied in depth what enables innovation. He wrote a wonderful book "Sidewinder: Creative Missile Development at China Lake"
@nicolefv Dr. Westrum writes about China Lake Research Labs: "its design and structure had one purpose: to foster technical creativity. It did; China Lake operated far outside the normal envelope... Sidewinder & others were "impossible" accomplishments, w/aplomb"

https://t.co/OjY5KSDbNK
@nicolefv I love this book because it describes traits of organizations that routinely create and maintain greatness: US space program (Mercury, Gemini, Apollo), US Naval Reactors, Toyota, Team of Teams, Tesla, the tech giants (Amazon, Google, Netflix, Google)
@nicolefv "Research and development is not a business that can be carefully planned and directed, not if you expect to make progress rapidly and economically." Burton Klein, Economist, 1958.

"What is the underlying science [and theory]?
@nicolefv "What accounts for successful innovation? What role do leadership and organizational design play?" What incredible questions!

"Today Rabinow, professional inventor w/230+ US patents, an advisor to NIST: 'all inventors come up w/many idea; you must know that most are trash."
@nicolefv One aspect Westrum hints at is need for constraints & scarcity. One factor for Sidewinder success is that it was hidden as an official program for years, classified as "fuse research," which could be easily classified.

This prevented expansions in budget, oversight, meddling
@nicolefv Counter-examples at this time were the Falcon (which became Phoenix), and Sparrow, both of which underperformed for years, unable to hit their targets.

Dr. Bill McLean is the center of the narrative, Ph.D. from Caltech, who led the program, and eventually China Lake
@nicolefv One dynamic with China Lake (let's call it CL) was minimum of organization and hierarchy: the important point: "Each person did the job for which they were best fitted. One day they'd be directing associates. Next day, it could be other day around."
@nicolefv In the interview, Dr. Westrum suggested that this is the opposite of a hierarchy, where managers tell workers what to do — instead, you want an org that give the job who can best do it.

That could be answering a question, dictating what the work should be, or doing the work.
@nicolefv Aside: that sounds kind of obvious, right? But contrast this to how many orgs actually work. This is about whether or not the organization respects knowledge.

"Lockheed Skunk Works shared many similar traits... Director "Kelly" Johnson promised P-80 Shooting star in
@nicolefv "...in 180 days; his hand-picked team did it in 141 days." Skunk Works was a small team, but China Lake had figured out how to scale this dynamic to thousands of employees
@nicolefv "Merle Tuve, maestro in charge of developing the proximity fuse in WWII, once said: "I don't want any damn fool in this laboratory to save money. I only want them to save time."

(Also resonates w/me. As @chawlady wrote: we stopped optimizing for cost, and optimized for speed)
@nicolefv @chawlady "Management theorist Deborah Dougherty argued successful products generally come from orgs whose design, mfg, sales, & marketing depts focus on meeting customer’s carefully studied needs.
@nicolefv @chawlady "Getting these four departments to focus on a common, well-chosen goal is the secret to success. What is remarkable about McLean is that he combined in a single person all these activities."

Dr. Westrum says that the literature calls this the "technical maestro"
@nicolefv @chawlady "In conceiving his missile, McLean determined to use “the minimum amount of garbage you had to hang on the rocket in order to make it home.” Experiments would tell him just how much garbage this was.."

(other missile programs burdened with lots of premature requirements)
@nicolefv @chawlady The dynamics of large, public, official missile programs (not Sidewinder): "years of effort go into preparing the systems, and often tests went badly. Millions of $$, and in some cases, fate of whole business divisions rode on the outcomes... Raytheon had 6K engrs on Falcon
@nicolefv @chawlady "...emotions ran high in the control room, and a man could break into tears when his missile failed." (painting the high-stakes dynamics in these massive programs that prematurely created rigid boundaries)
@nicolefv @chawlady Okay, taking a break. Will continue soon. I feel like I highlighted the entire book — I'm writing up my notes to clarify my own thinking on this. (thank you @RoamResearch)
...also, in addition to @nicolefv, while I'm thinking about it, my thanks to @jezhumble who first introduced me to Dr. Westrum's work, as it appeared in Lean Enterprise, and @allspaw, who sent me two of his papers over the years!

More to come later...

While watching the GameStop stuff has been mildly hilarious (I mean who doesn't like watching the financial elite squirm?) it's pretty clear that a whole bunch of folk have convinced themselves this is ACTUALLY some kind of revolutionary activity. It isn't. 1/


Sure, it's highlighted yet another way in which the bastards profiteer but that's about it, stick it on the pile with the fifty other pro tips to keep the poor, well poor... It's todays banter and tho a few folks might have egg on their faces, literally nothing will happen. 2/


GameStop's three largest shareholders have earned £1.5bn+ during this. They sit at the top of some 200 institutions which are rolling. Meanwhile the ersatz rebels are now watching the bubble, realising there is profit to be made and having a wibble. 3/


No doubt some TRULY believe they are taking part in some kind of revolution but frankly it's utterly absurd and the vast majority are in it for the lulz and to cash in quick.

I'm sorry to tell you this, but you don't own GameStop.

4/


The reality is, the scale of the economic disparity and corruption is simply vast. Billionaires loosing a few millions means nothing. They buy one less yacht and you continue to live meal to meal.

The "Free Market" changes a few systems and the abuse continues. 5/

OK, I guess I have a thing to say about the stock market. I have done kind of what these Reddit folks are doing with it, in that I have invested in the stock market when I was not at all rich, using parts of my paycheck that it probably wasn't wise to risk. I don't now. (thread)

But, like, it worked out okay for me. I even shorted some stuff. I didn't coordinate with anyone or whatever, but I don't think on the individual level the stock market is *inherently* malicious. If you're privileged, you're going to be exposed to it (through 401ks, etc.)

And I don't think it's wrong for people to try to make money off of it outside of the 401k/retirement context that's socially normal, *especially* if they're desperate like I was. There *are* strategies that you can use that, while risky, aren't exactly like gambling

Like, gambling is risky in a different way. You are always working with a fairly consistent set of probabilities in gambling, and they're never in your favor (outside of grey area gambling like between friends, where you could hypothetically actually still card count)

Anyway, like, on shorts: I don't think they're evil. I think they're dangerous. For an individual, a short always carries a small risk of individual bankruptcy. There's USUALLY not even a huge upside to them; they're not mystical or magical, they're basically reverse "longs"

Many traders have no consistency when sizing their positions.

The pros have this down to a science.

Here's my dead simple, 3-step guide to position sizing (and to outperforming 99% of other traders in the process):

Step 1:

Define how much of your account you're willing to risk per trade.

Personally, I never risk more than 1% of my account equity.

If I have $100,000 account, I will never risk more $1,000.

This ensures I will never blow up my account on one single trade.

There are successful traders who risk 2-3% of their account per trade, but I find it most calming to risk 1% or less.

The first step in this process is completely up to you - only you can dictate how much risk you can tolerate.

Step 2:

Look for entries & exits that are within 5% (preferably less) of each other.

This means if I buy a stock & have a 5% stop loss, I can put a 20% equity position on & still be risking 1% of my equity.

Your account will thank you w/ 20% in a stock that goes up 100%.

Step 3:

Position size using this formula:

Total equity (100%) / Trade Stop Loss %

So, if your stop loss is 4%, here's the math:

100% equity / 4% stop loss = 25% Equity Position Size

(assuming 1% equity risk).

Here's another hypothetical calculation:

A story of a brave woman who let her "breast" cut to protect the life of Netaji Subhash Chandra Bose!

Neera Arya was born on March 5 1902 in Khekra Nagar, Uttar Pradesh in a distinguished & eminent businessman Seth Chhajumal's family. Since her childhood,


2/21
She was a true nationalist & always had a vision of becoming a part of the freedom fighter movement. She was also reportedly accused as an undercover by the British Govt.

That was the time when her father's business was flourishing in Calcutta, though his business was..

3/21
spread across the country but Calcutta was the center of his business and that was one of the reasons why her education was done in Calcutta. During that period of time, she had learned quite a few languages along with Bengali, Hindi, English.

4/21
Her father got her married to a CID Inspector "Shrikant Jairanjan Das" in British India but they were two different individuals, Neera Arya was a true nationalist but her husband was a true British servant. She was highly motivated & she had an urge of getting us freedom..

5/21
so she ended up joining the Jhansi Regiment in Azad Hind Fauz after the marriage. It was the regiment that the British always accused them of spying on British Govt.

It was the time when Neera's husband Jairanjan Das was given the responsibility to spy on Netaji Subhash..

Agastya Muni & Kaveri River
#story
This is a story which describes how River Kaveri was brought on earth by Agastya muni. There was a king named Kavera lived in the Brahmagiri hills who prayed to Brahma for a child. He was blessed with a daughter whom he named Kaveri.


Agastya muni married her. A demon, named Shoorapadma, wanted to trouble people so he prevented rain from reaching South India. As a result famine occurred in South India.
Agastya Muni who came that way was very sad seeing this. He started to pray Mahadeva for a solution.


Shiva gave him small amount of Ganga water in his Kamandalu (small pot) and said wherever you spill this water the river will flow from there. Agastya Muni travelled lot of places to find a suitable place to pour water. Feeling tired he kept his Kamandalu and took rest.


At that time Ganesha took a form of crow and perched on the Kamadalu and made a hole that water began to flow as river Kaveri. This place is now called as Talakaveri (Karnataka), located in the Brahmagiri hill.


Tala Kaveri has temple for Agastheeswara, which denotes the story between Kaveri and Agasthya muni. Kaveri is a part of Ganga, thus, also called Dakshina Ganga.
