High tech\'s missionaries of sloppiness  -  car electronics system
Do you have a computer mouse nest?
In recent days, or even months, related issues have taken up your life ---
Ruin your work schedule, your leisure plan, and I'm sure you'll be craving the day I do if you have sleep, when computers and software companies cause more pain to consumers than any other industry, they are razed to the ground by the competitors they deserve ---
Network equivalent of AK-47.
This is the vending machine Kalashnikov 1947, which has surpassed all competitors for about half a century ---
Including its main US rival M16--
All over the world. The AK-
47 every attribute of my favorite product.
Type the name of this attack weapon in Google and you will find the website after the website lists the same shiny advantages: with the original model AK-almost no change
47 and its derivatives are deliberately simple in design, so easy and cheap to manufacture-
Most importantly, it is reliable that an estimated 40 million of people have done so far.
More complex M16 over the years--
Full of innovation-
Known mainly for interference.
Explain why people like me hardly need a psychiatrist-
He usually feels nauseous about the idea of a gun. -
When reminded that American computer companies are fully aware that their products are flawed and don't care, I should like to make up the arms business.
I'm not talking about the plan,dubious)
The idea of shortening life must be added to industrial products to ensure that there are enough customers in the industry to stay alive.
For example, I'm talking about not surprising information in the July issue of PC World ---
Reply according to 16,000 users-
Computer owners are having more trouble using machines than ever before, and few of them are satisfied with the quality of service of these products or manufacturers.
When analyzing the repair history of 13 products collected in the consumer report, PC World found that about 22% of computers fail every year ---
In contrast, 9% of video recorders, 7% of the size
Flat-screen TV, 7% dryer, 8% refrigerator.
I'm talking about a personal study.
Gartner's computer failure rate found that laptops used by large U. S. companies had a failure rate of 25%.
Kevin Knox, Gartner's technical director, said: "This means that one of the four notebooks will fail in a given year . " Who believes that this rate is likely to increase since the study was conducted three years ago.
All this is not accidental.
A careless culture seems to have taken over at the top. tech America.
Personal computers are unreliable shiny models because of the high
Today's technology industry has actually promoted laziness to a way of working.
Not long ago, Silicon Valley's market experience and venture capitalist Regis McKenna--
I'm editing a book for him. -
Tell me, high
Technical leaders who used to make a pilgrimage to Japan to learn about the quality circle and other quality control tools lost interest in the 1980 buzzwords.
They think their product reliability problem is the inevitable side effect of the product they are good ---
High speed innovation.
"The way we operate here is 'act quickly, solve the problem later, '" Regis said '. ".
He showed me the Stanford University Computer Industry Project study, which concluded that Japan always lags behind the United States in terms of software innovation and sales due to the business culture that is prevalent in perfectionism.
Researchers at Stanford University found that unlike Japanese computer companies, which are faltering by complex quality control and testing procedures, American companies accept "good enough" quality for speed.
Launching new products first is the highest goal here, and companies rely on huge technical support and customer service staff to deal with many of their commissions and omissions.
"Don't worry, crappy," Silicon Valley veteran and expert Guy Kawasaki expressed the same idea two years ago in a speech that won him a standing ovation.
He explained to 1,000 entrepreneurs that revolutionary products are not necessarily wrong.
Free: "Don't believe the first version must be perfect.
If the software industry is honest, they will tell you that the algorithm is: ship and then test.
"But what does it mean when the PC industry seems to say" First Edition.
New features are included in almost every product and software release, which can make most of our important computers
Related purchases in this category.
Computer and software companies can improve the reliability of their products.
But they don't.
13 years ago, 27-year-old Watts Humphrey
Old IBM, now a member of the Pentagon.
School of Software Engineering, Carnegie Mellon University--
A method of designing quality and reliability into software products is developed.
The core idea is that high-quality software development and manufacturing must be designed from the beginning;
It can't just "test" at the end of the process ".
So what about companies that complain about causing trouble to consumers?
Free products mean they will increase their prices by 50%.
Focusing on software development can significantly reduce overall development costs, says Humphrey.
A handful of American companies using his technology have shown surprising results.
For example, at Raytheon electronic systems, quality costs accounted for almost 60% of total production costs in 1990, and by 1996, the label had fallen to 15% and since then to less than 10%.
Humphrey believes that there is no excuse for software with problems.
"We should stop talking about software bugs as if they were just annoying," he said . ".
"They are defects and should be labeled like this.
He said, "Unlike software companies, many other industries produce high-quality products and take full responsibility for their defects.
"While commercial aircraft, like computers, have extremely complex hardware and software systems, their manufacturers do not shy away from liability for their defects.
But Humphrey has been ignored by the American PC industry.
Many technical experts pointed out that in the 1950 s and 1960 s, the American automobile industry's contempt for quality was similar and creepy.
Methods to promote W invention
Edwards Deming-
Humphrey's technology was built on this basis.
They predict that in the near future, some foreign computer industries that accept Humphrey's ideas will have an impact on American competitors, as Japanese automakers have done to Detroit.
Bryan Pfaffenberger, faculty at the School of Engineering and Applied Sciences at the University of Virginia, many experts remind us that the Japanese automotive industry has flourished by giving Deming the idea of a home: "Japanese automakers keep in mind Dai Ming's teachings," wrote Pfaffenberger. "They started to make some very good cars.
What's more, they are cheap.
As a result, Japanese automakers are nearly third in the U. S. market. S.
Market and most international markets.
"There is already a foreign country that worships 73-year-old Humphrey like Japanese Deming.
Of the 38 software companies around the world, 22 in India have adopted his method and are certified to meet the highest requirements of the Institute of Software Engineering-"Level 5" --
Quality standards. (
Four US companies, including Perot Systems and Citigroup, have Tier 5 subsidiaries in India. )
Last year, the Indian government and several Indian companies set up the Watts Humphrey Software Quality Institute in Chennai, southern India, and a contract software development company called Advanced Information Systems is producing software with 0.
There are 05 defects in every 1,000 lines of code-
"It's better than the space shuttle software," Pfaffenberger said . "-
As a result, its profits doubled.
People who criticize Humphrey
Quality Software scheme-
Implement strict performance measures for programmers-
Protests have hindered creativity. "[A]
Fine expression on the 19 th-
The concept of scientific management. . .
This is a good thing for this technology, because very few people will be disciplined as Humphrey proposed, "complained the technical critic of a book by quality experts, this is a software project on Amazon. com.
Programmers do not want to micro
From a psychological point of view, management may be understandable.
But victims of any defect
A personal computer with a lot of holes-
That is to say, almost every user of these machines-
It is unlikely that there will be too much sympathy for how they feel in this regard.
Speaking on our behalf is the growing number of respected computer scientists and engineers who believe that the era of interesting ideas for managing personal computer design and manufacturing is over, it has to give way to a person whose computer is seen by the creator as more like a bridge and a tunnel than, say, a house in Frank Lloyd Wright or Le Cobb.
So what can we do when the story of bad software killing people is still rare? They exist and may herald the future, James Morris, dean of the School of Computer Science at Carnegie Mellon University, recently proposed in an article that universities jointly promote research and education, government and industry that improve the reliability of computer systems.
He suggested calling it the Alliance for high-reliability computing (HDCC)
He warned, "many systems will become critical when we entrust our lives and Planning Commission to computers. . .
If a simple word processor crashes a few minutes before the delivery deadline for submitting a proposal, it may also be a key task.
Not even every day.
Raise key applications to a higher level of reliability to replace the huge hidden costs of their unreliable taxation of businesses and individuals.
"But contrary to the practice of the personal computer industry, Morrison's view is likely to belong to another galaxy.
Common sense seems to suggest that measuring defects is an important first step in eliminating them.
Incredibly, no one collects (un)
Reliability Statistics for personal computers and software.
"There is no independent organization collecting data today and the company itself will certainly not give any information about the performance of their products," Gartner's Knox said . ".
Common sense also seems to believe that understanding the root cause of the failure is essential to prevent recurrence.
However, in a short article Knox sent me, he wrote, "PC problems are rarely diagnosed.
Instead, apply a temporary solution immediately.
The accepted industry practice, he said, is "repair, not diagnosis ". . .
Instead of diagnosing and repairing specific systems, for example-
Level problem ,【
Computer company]
New motherboard components and BIOS may be applied immediately and it will never be possible to determine the root cause of the problem.
"It's like Kawasaki's" Don't worry, crappy "proposal on product development has become a slide permit for computer companies to operate in various fields;
Waste the carelessness of the company's own resources at will.
Even a computer.
The user can see this. Let me explain.
From 5 to October this year, Dell, the largest direct seller of personal computers in the United States, sold personal computers to consumers twice, and I had to replace the modem with a $3,600 portable machine, the machine was less than two years old and replaced its first deceased Lemon within six weeks of my initial purchase. (
With the help of Dell phone tech support, I'll let the reader imagine a few weeks of pointless trouble shooting ---
First represent one computer, then each of the two modems--
Made a deadline for my own work. )
After my second Dell modem fails, the company should send its on-
Use the new motherboard and the third modem to provide on-site service technology for my home.
But at the Dell warehouse somewhere in Texas, someone didn't put the motherboard on the plane, so the same service technician had to wait for another expensive overnight shipment, and called me another two days later.
When there was no benefit in replacing the two components, I was asked for Dell to send my machine to a repair shop in Tennessee, and my local air fast truck driver had to go to my house for the second time, because the reference number given by Dell employees is
The shipping company did not match the one she gave me.
At the end of all this, when I finally had a computer that was working fine again, no one at Dell could tell me why the reason for the recent episode of trouble was basically unknown. (
"Fix, don't diagnose. ")
There is also a huge example of inefficiency and waste.
In the early autumn, there were two different failures with my HP printer-
A little bigger than a year ago. -led to hours-
For a few days, the technical support staff called for a long time, and finally the technical support staff of the company told me that I needed the latest version of the software driver, I have to change my printer to a new one that they will send out.
The next day, the replacement printer arrived and shipped by Fed Ex, although it was completely useless without a new driver, I was told I had to wait a week.
Joann Osier, a kind HP tech support Lady, sympathized with me under the following circumstances-
I had two printers three weeks later but couldn't print anything-
I haven't received the promised software disc yet.
She said she would simply provide me with a copy of the sample she happened to be sitting at the table and she did.
About two months later, I thought of the good Samaritan with special gratitude, and when the software promised nearly three months ago finally appeared at my door: it had been (
Overnight priority)Fed-Ex.
Maybe the biggest irony of all this is, Gao-
Technology products mean that people do not make a small part of the innovation developed at an extremely fast speed, which should prove high. Backward technology.
First of all, many of them have more styles than material ones-
What computer scientists call "features-
It is "glitzware" or in reference to a later product --
Detroit 1950, "tailfin" and "flashy chrome bumper ".
"But it's not the worst.
In a joint newspaper column published in the Los Angeles Times in November.
27. Gary Chapman, director of the 21st century program at the University of Texas, social impact authority for new developments in information technology, it is noted that "the repeated experience of software failures often reduces people's use of computers to the familiar and regular range.
Research shows that most users have less than 10% functional dependencies on common programs such as Microsoft Word or Netscape Communicator.
A high degree of tolerance for setbacks and failures is to explore boundaries that transcend their comfort levels. . .
It also raises questions about how much money and effort we spend on new software features that most people don't even know.
In an article on computer reliability by James Morris of Carnegie Mellon University, he wrote, "in the 1950 s, something good for the automotive industry was good for the United StatesS. . . .
Like 1950 of car quality, it is generally believed that making software more reliable is a harm to shareholders. . . " I e-
Sent to him a few days ago and asked what he thought was needed before the situation ended.
In his reply, he mentioned that some Silicon Valley companies, as well as NASA and his university, will launch his creative-high reliability computing alliance on Monday.
But he did not raise his consciousness.
To act as the most likely agent of change (
He did not answer my supplementary question about American computers or software companies at all ---
Relative to universities and government agencies-
A large amount of funds or resources have been invested in the project. )
"Until consumer demand [quality]
The defending company will believe that it will be obtained from overseas, "he said. mailed me.
"In the current environment, computer and software companies in the United States make too much money. "
