There is no scientific method of "trial and error", not as "missing." Workplace life, lumpy - "trial and error" is more useful than expected and effective "trial and error" can often achieve unexpected results, in order to come to find a better career development.
First, how to make better choices? trial!
The story of the Wright brothers invented the airplane, we all know, but this time on the "track", there are many teams in the competition, one of the most promising people project scientist Samuel Pierpont Langley, he has received the US government and large research the funding.
The Wright brothers is a standard civil division, had never graduated from high school, a bicycle shop on aircraft research and development money, naturally not being optimistic.
One of the reasons the ultimate success of the Wright brothers, and later was analyzed, they fully adopted a very scientific method - wind tunnel experiments.
Wanted to build a aircraft can fly overhead, there is no theoretical problem, the real challenge is to try to extend flight time under complicated weather conditions, which need to get a lot of aerodynamic test data, and then continue the transformation model. Aircraft can this thing, once the failed flight, the aircraft destroyed is small, people are not just all over.
Two did not have a technical Wright brothers funds, only to be scientific way, they noticed a British invention - the wind tunnel and created the world's first wind tunnel tests can accurately model the wing.
Now look at the wind tunnel is a very big thing on the light going to do an experiment seven digits, but a hundred years ago the Wright brothers made out of, but it is like the following:
Do not underestimate it, the Wright brothers took advantage this thing, made more than 200 different wing wind tunnel experiments carried out thousands of times, made a set of scientific data, design the shape of the wing of a larger lift.
One hundred years later, Tongji University 1: 1 copy of the Wright Brothers wind tunnel, experimental results, simple go simple, does give a relatively accurate aerodynamic data.
The reason to use the beginning of the story, because the Wright brothers gave us an idea to solve a very difficult problem - how low-cost trial and error.
But also an important way, "fuzzy correct" concept "trial and error."
Second, the technology can not be separated again Niubi trial and error this link
There is a failure is inevitable, but recurring, so some people do not call it a failure, called "trial and error" - said Lei Jun: have the opportunity to try, in fact, of trial and error cost is not high, but the cost of missed very high.
The statement is not right, trial and error time cost is very high, unless you can reduce costs and find a more efficient way.
I saw online someone Tucao, Tesla car battery that is not high-tech, in fact, is the thousands of pieces of Panasonic laptop battery cell and bind them in a pile.
Well, this statement is actually not wrong, as if to say "pizza pie yard is not meat", but the key is how the connection, where in parallel, in series where, how control program may be thousands.
Tesla battery design is to end these possible, select some reliable design, simulation measurement, comparison, go back improvements, repeated trial and error, and produced the world's most stable battery power system,
You see, then Niubi technology is also inseparable part of this trial and error, however, trial and error, after all, there is a cost, there must be some better means to reduce the cost of trial and error.
A few days ago after listening to Ali cloud machine intelligence chief scientist of Mr. Min miles of a speech, he has a point: the era of artificial intelligence, big data, the algorithm is not critical, that all the principles of the algorithm are several papers nineties, nor is it considered force issues, cloud computing getting cheaper.
The key is to become a huge problem needs a little "pain point", to design a "low-cost trial and error process," come to the preliminary solution, then small step rapid iteration. The maximum effect of this "process" is the man can play.
"Wind tunnel" the era of big data is artificial intelligence, low-cost real-life simulation of a particular scene, through cloud computing "massive force considered" the accumulation of data, find the best solution.
This is one of the most critical is the "low cost + instant feedback system."
Novice workplace learning and growth process, the principle of "low-cost trial and error" applies equally, also need these two conditions.
Third, the personal work of instant feedback system
Look at the first condition: the design of a "real-time feedback system"
Learn a musical instrument, as long as a good teacher, a step by step tutorial and repeated training for a long time, because every little progress, you can clearly feel that the teacher can remind you where the problem.
Playing, sports, most of the physical labor, some simple technical labor, are born with the "instant feedback system."
But so did most of the work directly, such as sales, you have mastered a sales technique, may have failed several times before, probably because you are not skilled, it could be customers themselves do not have the will to buy. Be worse, you can not know in the end the answer is wrong, or do you use well, so you will not be able to improve.
Most have some technical content of the work, they can not direct feedback effect, you have to design a "real-time feedback system", thinking there are two, one is the "subdivision", the second is "to complicated."
Look at the "subdivision."
On one occasion, Liu Qian do a dress rehearsal before the magic show, so suddenly stopped when a link, ask the broker sitting in the audience: "speech here yesterday, why the audience laugh?" She asked the broker to live, he the day before in the audience, did not feel ah.
Magic and the general performance of different, demanding the audience reaction, he must clearly know where the audience will be holding their breath, where you will be staring at where burst into applause. Way to practice magic show is that the whole process of "subdivision", the feedback with the audience one-up action, any minor for unanticipated reaction, should be sensitive to perceived, then targeted exercises, in order to continuously improve the level of .
Almost all of the work can be found to "subdivision instant feedback" section:
Seller should sell in a typical scenario factored out the design, then surgery, access to each other's feedback; designers should "visual representation" link factored out, get feedback collaborators; managers have to take "effective communication" core areas, get feedback from subordinates ...... another is "to complicated."
Such a thing often happens at work, you do a great program, speaking at a conference on the results we have put forward their views, not to say that the cost is too high, that is not good grasp of time, from the beginning of cold water poured into the pots feet, this feedback is really too bad.
In fact, this is normal, without any design of a "feedback system", there must be a lot of noise departure from the original intention, "to fan" approach is the only thing you every core concern of feedback.
For example, this program your design goal is to "improve efficiency", and that at this point as long as the feedback is positive, we can give you motivation, you can iterate programs on this basis; if you do not hear feedback in this area, you must take the initiative to get through certain words have surgery and know the reason, then make improvements.
"Subdivision" and "de-Fan" is to create a "direct feedback system", which is the premise of trial and error.
Another is the "low cost", which is how to do it? After all, people are not machines, can not handle big data.
Fourth, more cost-effectively to trial and error
In the various stages of his career, will encounter their own problems, we need to keep the "trial and error." But people are not machines, repeated "trial and error" process, will make you self-doubt - I was in the end it is appropriate that road?
"Vague correct" an article in the series, which talked about a point, when you see the career direction, back to the "interests" and "personality characteristics" to think about the origin of these two.
"Interests" and "personality characteristics" is important, one reason is that when you are still a novice, they can make you a more cost-effective to trial and error.
If you like something, you are more likely to ignore the frustration you have experienced, this is the "interests" of low-cost trial and error; the contrary, if it is a fad "pseudo-interest," you simply can not endure lengthy "trial wrong "process, can not overcome this boredom as a career.
If your character is more suitable to do a certain thing, it means you've accumulated some "historical data" and "algorithm", you may experience fewer failures of some, this is the "character traits" to bring low-cost test wrong.
His career has a lot of "trial and error" process, the competition of short remote is "trial and error efficiency", and "trial and error efficiency" It depends on two things:
1, does not deviate from the "fuzzy correct" general direction;
2, lower cost and more efficient feedback.
