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...

CHEAT-SHEET

Multiple Confirmation short.

A Short Entry that we shared in 2020.

Study it point wise.

1. Bearish Candle type and lowering of volume on Price rise.

2. OBV divergence.

3. Accumulation with Bearish candles and Volume increase on Price decrease.

STUDY IT!


Explanation

1. When price increases with a decreasing volume, it's bearish.

2. OBV, On Balance Volume should be correlated with price.
If price increases without similar increase in OBV, it's bearish.

3. During consolidation, if the volume increases during dumps, it's bearish

A thread on Pyramiding-


What is pyramiding?

In pyramiding we add on to a position when it is going in our direction. Its basically opposite of averaging down.

MOMENTUM - Success of a pyramiding trade depend on this ingredient, the more the momentum the better pyramiding.


There are many way to enter and exit in a stock-

1. ALL IN - ALL OUT
2. ALL IN - SCALE OUT
3. SCALE IN - SCALE OUT
4. SCALE IN - ALL OUT ( I use this one)

Why traders use Pyramiding ?

More than anything what pyramiding do is keep your losers small and your winners - Big.

Pyramiding in my view keeps your dd smaller as your losers are very small because you enters with only a fraction of what you would have entered Normally.

BUT, not necessarily it should be more profitable than ALL IN- ALL OUT, Where one enters all at once and sell all at once.

HOW TO DO PYRAMIDING-

There are various methods which are used by traders for pyramiding ,while keeping the basic concept of adding onto the strength.

1. PYRAMIDING AND TRAILING BASED UPON STRUCTURE-

In this method we scale in or pyramid the qty when the stock breaks above

1/ I used to think that the biggest gains had to come from stocks that no one knew about

One of the harder lessons for me to internalize has been that oftentimes, unknown stocks stay unknown for a reason and you can still earn attractive returns from stocks everyone's bullish on

2/ While I’m not contrarian just for the sake of being contrarian, I do think it’s important to question everything.

When I started out, I would buy "quality" stocks like FB or TSLA without doing much research.

But an opinion being consensus doesn’t make it the truth.

3/ So owning the most popular stocks made me nervous. If a winner is so obvious then either it's priced in or maybe I'm missing something?

I preferred owning stocks that others weren’t aware of or were bearish on for the wrong reasons (more room for upside surprises).

4/ But there are degrees

Despite being widely popular, stocks like SHOP have been some of the best performers because they exceeded even the most bullish projections

And some stocks like TSLA are partly popular because they are great consumer products which is an important sign

5/ On the other hand, while the biggest winners can be found in micro-caps, many of which started out very undervalued with no analyst coverage, on average, they tend to underperform larger caps

Picking out the big winners earlier on is very difficult and there is no set formula

“In search of the holy grail”

A thread-


Holy grail- A strategy Which can make money all the time.

After going through two phases of a traders journey, the initial success phase, and Only why do i get loss phase, Traders enter the third phase -

THE SEARCH FOR THE HOLY GRAIL PHASE.

This phase has no limits, It can end in 1 month and it may not end till lifetime.

What exactly is this phase?

When a trader covers all the basics, they know how to lower their losses, they know the power of risk management.

And few of them may even develop their edges and systems over time.

But after some time, they feel that they are doing something wrong and there is more to trading than what they know.


THEN COMES THE HOLY GRAIL PART-

Few of them start to Read more books about trading,finding articles about “How to win 100% of the time” and listening to Youtube videos of few big traders who make big in trading.

SRI KALAHASTI KSHETRAM, CHITTOOR (AP)
#bharatmandir

Panchbhootasthalam representing vayu element, also called Dakshin Kailasha.
As per Shiva’s boon, Vayu is incarnated here as Shiva and worshipped as Kalahasteeswara.
The kshetram is also associated with Rahu and Ketu.


The Kshetram is named after 3 devotees of Shiva- a snake, spider and elephant who worshipped a lingam in the forest. Elephant did jal abhishek with water from its trunk, spider protected it from dust by weaving a web on it and snake adorned it with his jewel.
@GunduHuDuGa


Once, the web and jewel got washed away when elephant sprayed water on the lingam. Angered snake entered elephant’s trunk and bit him but died in the process. The agitated elephant trampled the spider accidentally. Shiva gave moksha to all three.


Hence the name-Sri for Spider, kaal for snake n hasti for elephant.

Shiv bhakt Kanappa is said to have plucked his own eye to put it on the lingam here when he saw blood oozing from the eye on the lingam
This place is the ultimate location for Rahu Kethu Sarpa Dosha Nivarana.

💬 I often get Q’s like these:

How did you get your first customers for WIP? How did you grow BetaList’s traffic? Etc.

Makers are looking to reverse-engineer success. I see it everywhere.

I don’t think it works that way and the answers to those questions are mostly useless. 💥

I have built dozens of different products over the last couple of years. The vast majority failed. 😭

Surely if I know the answers to these questions, but still fail over and over again, these answers aren’t that useful. 🤷‍♀️

So what’s a better question to ask? 🤔

99.9% of the questions I receive are about the products that did well. In a way that makes sense, because we quickly forget about those that didn’t succeed.

🧠 This is known as survivorship bias.

Focusing on what survived, while ignoring what made it survive in the first place.

The real question, what you really want to know, is this:

What makes @WIP, @BetaList, and to some extent @AllStartupJobs succeed where my countless other attempts failed?

What separates a failed product 👎 from a successful product 👍?

Honestly, I don’t know. I wish I did.

It’s like Steve Jobs said “I’ll know it when I see it.” 👀

Same is true when we make products. We don’t know upfront what will work. But once we see an inkling of a product that does have potential, it’s not that hard to spot.

Thread A History lesson for the MOAB:
1. The United States of America is not and has never been a Democracy, we're a Federal Republic tied together by the capital Laws of the Constitution.

Everyone in the country is about to get a harsh lesson on what this really means...

2. In 1871, February 21: Congress Passes an Act to Provide a Government for the District of Columbia, also known as the Act of 1871.

With no constitutional authority to do so, Congress creates a separate form of
government for the District of Columbia.

3. A ten mile square parcel of land (see,
Acts of the Forty-first Congress,” Section 34, Session III, chapters 61 and

4. The act — passed when the country was weakened and financially depleted in
the aftermath of the Civil War — was a strategic move by foreign interests
(international bankers) who were intent upon gaining a stranglehold on the coffers and neck of America.

5. Congress cut a deal w/ the international bankers(Rothschilds of London) to incur a DEBT to said bankers. Because the bankers were not about to lend money to a floundering nation w/out serious stipulations, they devised a way to get their foot in the door of the United States.
