LEAN STARTUP


Stop me if you’ve heard this one before. Brilliant college kids sitting in a dorm are inventing the future. Heedless of boundaries, possessed of new technology and youthful enthusiasm, they build a new company from scratch. Their early success allows them to raise money and bring an amazing new product to market. They hire their friends, assemble a superstar team, and dare the world to stop them.
Ten years and several startups ago, that was me, building my first company. I particularly remember a moment from back then: the moment I realized my company was going to fail. My cofounder and I were at our wits’ end. The dot-com bubble had burst, and we had spent all our money. We tried desperately to raise more capital, and we could not. It was like a breakup scene from a Hollywood movie: it was raining, and we were arguing in the street. We couldn’t even agree on where to walk next, and so we parted in anger, heading in opposite directions. As a metaphor for
our company’s failure, this image of the two of us, lost in the rain and drifting apart, is perfect.
It remains a painful memory. The company limped along for months afterward, but our situation was hopeless. At the time, it had seemed we were doing everything right: we had a great product, a brilliant team, amazing technology, and the right idea at the right time. And we really were on to something. We were building a way for college kids to create online pro􀀡les for the purpose of sharing … with employers. Oops. But despite a promising idea, we were nonetheless doomed from day one, because we did not know the process we would need to use to turn because we did not know the process we would need to use to turn our product insights into a great company.
If you’ve never experienced a failure like this, it is hard to describe the feeling. It’s as if the world were falling out from under you. You realize you’ve been duped. The stories in the magazines are lies: hard work and perseverance don’t lead to success. Even worse, the many, many, many promises you’ve made to employees, friends, and family are not going to come true. Everyone who thought you were foolish for stepping out on your own will be proven right.
It wasn’t supposed to turn out that way. In magazines and newspapers, in blockbuster movies, and on countless blogs, we hear the mantra of the successful entrepreneurs: through determination, brilliance, great timing, and—above all—a great product, you too can achieve fame and fortune.
There is a mythmaking industry hard at work to sell us that story, but I have come to believe that the story is false, the product of selection bias and after-the-fact rationalization. In fact, having worked with hundreds of entrepreneurs, I have seen 􀀡rsthand how often a promising start leads to failure. The grim reality is that most startups fail. Most new products are not successful. Most new ventures do not live up to their potential.
Yet the story of perseverance, creative genius, and hard work persists. Why is it so popular? I think there is something deeply appealing about this modern-day rags-to-riches story. It makes success seem inevitable if you just have the right stu􀀯. It means that the mundane details, the boring stu􀀯, the small individual choices don’t matter. If we build it, they will come. When we fail, as so many of us do, we have a ready-made excuse: we didn’t have the right stu􀀯. We weren’t visionary enough or weren’t in the right place at the right time.
After more than ten years as an entrepreneur, I came to reject that line of thinking. I have learned from both my own successes and failures and those of many others that it’s the boring stu􀀯 that matters the most. Startup success is not a consequence of good genes or being in the right place at the right time. Startup success can be engineered by following the right process, which means it can be engineered by following the right process, which means it can be learned, which means it can be taught.
Entrepreneurship is a kind of management. No, you didn’t read that wrong. We have wildly divergent associations with these two words, entrepreneurship and management. Lately, it seems that one is cool, innovative, and exciting and the other is dull, serious, and bland. It is time to look past these preconceptions.
Let me tell you a second startup story. It’s 2018, and a group of founders have just started a new company. Their previous company had failed very publicly. Their credibility is at an all-time low. They have a huge vision: to change the way people communicate by using a new technology called avatars (remember, this was before
James Cameron’s blockbuster movie). They are following a visionary named Will Harvey, who paints a compelling picture: people connecting with their friends, hanging out online, using avatars to give them a combination of intimate connection and safe anonymity. Even better, instead of having to build all the clothing, furniture, and accessories these avatars would need to accessorize their digital lives, the customers would be enlisted to build those things and sell them to one another.
The engineering challenge before them is immense: creating virtual worlds, user-generated content, an online commerce engine, micropayments, and—last but not least—the three-dimensional avatar technology that can run on anyone’s PC.
I’m in this second story, too. I’m a cofounder and chief technology officer of this company, which is called IMVU. At this point in our careers, my cofounders and I are determined to make new mistakes. We do everything wrong: instead of spending years perfecting our technology, we build a minimum viable product, an early product that is terrible, full of bugs and crash-your-computer-yes-really stability problems. Then we ship it to customers way before it’s ready. And we charge money for it. After securing initial customers, we change the product constantly—much too fast by traditional standards—shipping new versions of our product dozens of times every single day.
We really did have customers in those early days—true visionary early adopters—and we often talked to them and asked for their early adopters—and we often talked to them and asked for their feedback. But we emphatically did not do what they said. We viewed their input as only one source of information about our product and overall vision. In fact, we were much more likely to run experiments on our customers than we were to cater to their whims.
Traditional business thinking says that this approach shouldn’t work, but it does, and you don’t have to take my word for it. As you’ll see throughout this book, the approach we pioneered at IMVU has become the basis for a new movement of entrepreneurs around the world. It builds on many previous management and
product development ideas, including lean manufacturing, design thinking, customer development, and agile development. It represents a new approach to creating continuous innovation. It’s called the Lean Startup. Despite the volumes written on business strategy, the key attributes of business leaders, and ways to identify the next big thing, innovators still struggle to bring their ideas to life. This was the frustration that led us to try a radical new approach at IMVU, one characterized by an extremely fast cycle time, a focus on what customers want (without asking them), and a scientific approach to making decisions.


There Are So Many Things To Write



That many of them go out of sight,
I lament for them,
But immediately I can not recall the same.
They may accuse me,
But I don't want to flee,
Nothing in this world is trivial,
Everything is somehow essential.
I appeal to them to forgive me
And encourage me with glee;
I must find out them patiently and cautiously
And depict them distinctly.

THE WORLD OF POETRY


The World Of Poetry
The poets write poetry
And fill the world with vitality,
They may sleep in the cemetery,
But their existence for ever is a reality.
The poets depict their imagination independently
And the readers read it in an ecstasy,
The world of poetry moves confidently,
As the poets are superior to their fancy
No one can live without poetry,
As it will destroy his or her tranquility.

THE WILD ANIMALS IN THE CIRCUS



In the big ground the circus is in full swing,
The people enjoy it greatly and spring,
The clowns and the wild animals are busy in their work,
The lions, the tigers, the elephants are sharp,
But with the drudgery of work
They have certainly lost their glory and spark.
The wild animals are wild in nature and stature,
But they can not be so in this sphere,
As they have been well trained to behave in this submissive way,
From the strict and rigorous hand they can never sway.
The clowns are obliged to play their role in the circus,
But we are the most significant clowns of the world,
As we enjoy here the wild animal's living carcass.

THERE IS NO WAY TO ESCAPE


There is no way to escape,
Though the sages always think for this sake,
The fact is beyond control,
we have already begun to crawl.
Presently 'Progress' is not so in the true sense,
As it has lost the features of its essence,
In fact, we have developed our eccentricity
And the word 'dignity' is no more our identity.
Enmity and violence have destroyed our society,
We are now put in its captivity,
The divine blessings should fall on this land
To remove from here the filthy sand.


METHODS OF CASTING'S


Methoding of castings is a complex science. It involves the basic selection of :


(i) Design and construction of pattern equipment
(ii) Processes and practices for moulding, core making and core setting
(iii) Risering and gating system

Apart from the above technical parameters, clue consideration
sl poi ld be given for economic factors while methoding the castings. 

The following points should be considered :
1. Type of moulding and core making process
2. Position of the casting in the mould box
3. Suitable joint line
4. Suitable mould box size
5. Type of mould and core making materials
6. Material specification
7. External and internal chills if permissible
8. Chaplets if permissible
9. Mould and core checking and setting gauges
10. Sequence of core setting
11. Provision of vents and flow offs.
12. Number of pieces to be produced
13. Type of material for pattern and core boxes
14. Pattern and core box details
15. Placement of identification codes
16. Indication of surfaces for marking and machining
17. Estimated yield percentage of the castings
While deciding the suitable method of manufacturing the intricacies of the concerned job should be analysed from all the angles and the final acceptable casting concept decided, considering the resources available within the foundry.
