Love Marriage: Resembles procedural programming language. We have some set functions like flirting, going to movies together, making long conversations on phone and then try to fit all functions to the candidate we like.
Arranged Marriage: Similar to object oriented programming approach. We first fix the candidate and then try to implement functions on her. The main object is fixed and various functions are added to supplement the main program. The functions can be added or deleted.
Love Marriage: It is a throwaway type of prototype as client requirements rises with time thus it is a dynamic system and difficult to maintain.
Arranged Marriage : Requirements are well defined so use of waterfall model is possible.
Love Marriage: Family system hangs because hardware called parents are not responding.
Arranged Marriage: Compatible with hardware Parents.
Love Marriage: You are the project leader so u are responsible for implementation and execution of PROJECT- married life.
Arranged Marriage: You are a team member under project leader parents so they are responsible for successful execution of project Married life.
Love Marriage : Client expectations include exciting feature as spouse cooking food, washing clothes etc.
Arranged Marriage: All these features are covered in the SRS as required features.
Love Marriage: Acceptance test possible you can try before you Buy.
Arranged Marriage: Product is sold on an as is where is basis, Product once sold will not be taken back !

Power of Engineering: Jeep Hurricane
If you're into off-roading and we mean really into it then Daimler-Chrysler recently unveiled the vehicle of your dreams. It's a Jeep with more horsepower, more climbing ability and more steering options than any car ever made. With two HEMI engines and the ability to turn itself completely around in place, the Jeep Hurricane concept car is truly one of a kind.
This vehicle is the ultimate proof of Jeep's absolute dominance off-road .
Watching Hurricane in action, it's hard not to imagine all the potential applications for the military, for extreme off-roading and more. 
The fact is, we will do whatever it takes to ensure that there's only one SUV at the top of the mountain.
With more than 14 inches (36 cm) of ground clearance and 20 inches (51 cm) of suspension travel, the Hurricane is in a class of its own when it comes to off-road capability.
With more than 14 inches (36 cm) of ground clearance and 20 inches (51 cm) of suspension travel, the Hurricane is in a class of its own when it comes to off-road capability.The four-wheel independent short/long-arm suspension system is dampened by coilover shocks with remote reservoirs 
(this allows for longer travel in the shock). The 20-inch wheels hold specially designed off-roading tires that are 37 inches tall.
(this allows for longer travel in the shock). The 20-inch wheels hold specially designed off-roading tires that are 37 inches tall. Chrysler reports an approach angle of 64 degrees and a departure angle of 86.7 degrees.
The Hurricane is more than just a Super Jeep. It also represents an attempt by Chrysler's engineers to combine excess (it does have two HEMI engines)
with responsibility (new technology allows the Hurricane to operate on as few as four cylinders). The Hurricane's steering system is a marvel of engineering all by itself.
with responsibility (new technology allows the Hurricane to operate on as few as four cylinders). The Hurricane's steering system is a marvel of engineering all by itself. There are multiple steering modes using four-wheel independent steering. That means that each wheel can turn separately from the others. 
In standard steering mode, the rear wheels turn in the opposite direction to the front wheels, which tightens the turning radius and makes for more accurate steering. In a second mode, the rear wheels turn in the same direction as the front wheels, meaning the Hurricane can "crab-steer" -- move to the side without changing the direction that it faces.

In a second mode, the rear wheels turn in the same direction as the front wheels, meaning the Hurricane can "crab-steer" -- move to the side without changing the direction that it faces.
A third mode, utilizing the "T-Box Zero Steer" mechanism, allows all four wheels to "toe-in" and changes the drive direction to each wheel so that they alternate. The result? The Jeep Hurricane has a turning radius of zero. The Hurricane can actually rotate in place.

A group of 7 Sardars
There is this group of 7 Sardars who plan to go to Delhi to thank the President Dr. Zail Singh for his revolutionary policies, from which they have greatly benefited. Moreover, they are his old friends, and are longing to dine with the president. They agree that it would be appropriate to use a taxi. So they go to a taxi driver and ask him how much a ride would cost. The driver frets a little and tells them,"Sahab! If only four of you were to be there I would charge you just the meter rate, but then since seven of you would be there, you have to give me Rs. 10/- more." The Sardars agree and decide to take the taxi. The taxi driver takes them to Rashtrapati Bhavan. The meter shows Rs. 18/-, so the taxi driver says,"You have to pay me Rs. 28/-." Now, the Sardars have to share the cost among themselves and so they decide to divide the total (Rs. 28/-) by the number of people, i.e. 7. This is how they do the calculation to arrive at the answer:
The driver (naturally) is exceedingly happy upon receiving Rs. 13/- from each of the Sardars. He thanks them profusely and the feeling of exultant happiness is writtern on his face as he leaves them and proceeds his way. Seeing this, the Sardars feel that they may have made a mistake. They decide to ask Zail Singh about it. After all, the fellow was the President of the nation! After all the initial formalities are completed, they ask Zail Singh to check their calculation of the taxi fare. Zail Singh ponders over the calculations and finally says, "See, I am not good at division. The process just boggles me but addition is something I am an expert at. Let us add all the amounts you guys gave to the taxi driver and check the result. This is how I do for those tax forms I get very often. The process is slow but is sure." The other sardars nod their heads (?) in appreciation. The President writes as shown below and also explains as he writes on: 13+13+13+13+13+13+13= 28 i.e. 3+3+3+3+3+3+ 3= 21 and 21+1+1+1+1+1+ 1+1=28 so this checks out. He then says, "Yes, it's correct. But I can also call my close friend and Finance man Manmohan Singh. It is always better that he rechecks it. After all, he is a Finance man, you know!" Manmohan Singh arrives, and when told of the problem, he replies that he doesn't think it is a bad deal but says, "No problem! I will verify it via mathematical computation. I'll verify it with multiplication. That is the best technique for this, you see!" While others watch in admiration, Manmohan Singh goes on to write as shown:
This checks out as well.Then he says,
"This is really fine. There should be no problem, President Sahab. After all, it is correct in all the methods."
Peace reigns at the President's residence as the inhabitants and guests remain in quite contentedness while they reminisce about their astute abilities on solving a problem in a successful fashion

Difference between Focusing on Problems and Focusing on Solutions
Case1 :When NASA began the launch of astronauts into space, they found out that the pens wouldn't work at zero gravity (ink won't flow down to the writing surface). To solve this problem, it took them one decade and $12 million. They developed a pen that worked at zero gravity, upside down, underwater, in practically any surface including crystal and in a temperature range from below freezing to over 300 degrees C.
And what did the Russians do...??
They used a pencil.
Case 2 :One of the most memorable case studies on Japanese management was the case of the empty soapbox, which happened in one of Japan 's biggest cosmetics companies. The company received a complaint that a consumer had bought a soapbox that was empty. Immediately the authorities isolated the problem to the assembly line, which transported all the packaged boxes of soap to the delivery department.
For some reason, one soapbox went through the assembly line empty. Management asked its engineers to solve the problem.The engineers worked hard to devise an X-ray machine with high-resolution monitors manned by two people to watch all the soapboxes that passed through the line to make sure they were not empty. No doubt, they worked hard and they worked fast but they spent a huge amount to do so.
But when a rank-and-file employee in a small company was posed with the same problem, he did not get into complications of X-rays, etc.,but instead came out with another solution. He bought a strong industrial electric fan and pointed it at the assembly line. He switched the fan on, and as each soapbox passed the fan, it simply blew the empty boxes out of the line.
Moral Of The Story : Always look for simple solutions. Focus on solutions not on problems.
