Simple things and work can be directly simplified, and the detailed operation steps of each step, such as international parcel delivery, such as viscosity test of api bentonite, can be made into a common corresponding "standardized process" in work, so that every employee can complete a test according to the process and ensure the quality of work.
For some complicated work, it is impossible (and should not) to use standard workflow, so it is necessary to set up several principles or checklists to check whether you have paid attention to a reminder and made a common mistake, such as dealing with customers, using "you" as a sign of respect, using "professional expression" instead of "this thing" as a chat term to introduce products, and whether your speech is too repetitive. Not only things dealing with people, but also things that need to be handled flexibly because of many variables, which can not be realized by simple "workflow" and need to be replaced by "list"
Finally, nature is the most complicated work, involving creative thinking. For example, to develop a new product and solve a customer's technical problem, neither "standardized process" nor simple "list" can be used. Due to the diversity of problems, the checklist needs to be very abstract and universal, and has been upgraded to "universal problem-solving methodology".
Simple methodology is simple principle, complex methodology is advanced principle, and the most advanced methodology is a process composed of principles, such as six sigma statistical analysis (the most classic is hypothesis testing) and TRIZ. This is also the reason why I study the two, from tactics to strategy, from avenue to simplicity, "methodology casts magic" (a sentence from McKinsey-McKinsey is not mysterious, methodology casts magic).
6sigma methodology is a methodology for solving and analyzing problems based on statistical data analysis, while triz is a methodology for solving problems and innovating by emphasizing thinking flow and analysis flow.
From the perspective of "Tao and skill", the simpler things are often "tactics or skills". With the improvement of proficiency, some processes become "points", just like riding a bike and driving, which are the result of skill training. More complicated things focus on "strategy or Tao", which is what the so-called "losing for Tao" means. The more complex the problem, the more abstract and simplified the corresponding solution, but the advantage is that it is universal enough.
Many people don't even know the most basic analysis problems, just like the "trial and error method" mentioned by triz. They can only rely on random thinking (daydreaming) and experience (it is difficult for newcomers to sum up experience), not to mention the more complicated 6sigma and Triz.
I will briefly summarize several problem-solving principles obtained from reading and tested by work practice as part of combing experience. Using these small principles to guide the thinking direction in work and life can solve many problems.
In the process of sorting out, I sorted out some slightly complicated principles and issued them as later "advanced principles".
The answer should come from the book Is Your Light On. The simplest definition of the problem is the gap between the goal and the status quo.
To solve any problem, we must first use the principle of 1 to guide us to think about "what is the status quo" and "what is the goal".
This is the A3 form at work, considering the current situation, background and problems respectively.
Let's not talk about this for the time being, and the importance cannot be overemphasized.
Continue to analyze according to the principle 1, "What are we going to achieve?" What is the ideal result?
The term in Triz is "ideal tactics", which represents the state of eliminating (rather than compromising) technical contradictions.
Starting from the principle of 1, the simplest definition of the problem is what is the core contradiction. Because the simplest definition of a problem is the obvious difference in function or demand, we should find the "core contradiction" by further clarifying the problem.
Many times we take it for granted that contradictions exist, so there is no real solution to the problem, just simple optimization under contradictions. This is not innovation, and this is exactly what TRIZ emphasizes. So we must know what is the most rational state and what is the core contradiction.
Principle 3 comes from the book "Professor McKinsey's Thinking Weapon"-Zero | Wu Yukun's personal homepage. The book divides comparison into three categories: contrast, composition and change. Contrast is the most common, which is a special kind of data (total 100%), and the change emphasizes the contrast with time.
The importance of principle 3 cannot be overemphasized. In fact, the principle of 1 is also a "contrast", which is only taken out separately for further emphasis.
There is a comparative process behind the conclusion, but it is often ignored or hidden by us intentionally or unintentionally. Work is everywhere, and even the advertisements you see every day are carefully compared.
Of course, there are more restrictions on the comparison at work, such as the following emphasis on the data reading notes in the World of Statistics 1/2, which is the basic requirement for the observation and experiment of variable variables.
For the variable with large fluctuation, the comparison experiment should increase "randomness", so the best evidence to prove the existence of causality comes from the random comparison experiment, which can rule out the situation that the survivors are biased or partially unable to replace the whole.
If we go further, the comparison should be "double-blind", excluding human error, and extracting a sentence from Beyond IQ as the focus.
Analyze the problem in principle, don't just look at the superficial relationship.
Many people, including me, may have learned the first principle from Musk's introduction. Now many books will emphasize this principle, which is actually the embodiment of the "avenue to simplicity" emphasized above. There are more and more problems. Only by mastering the basic scientific principles or laws behind things can we use them flexibly and draw inferences from others, instead of floating on the surface.
The first principles of the physical world are basic scientific knowledge, physical chemistry and biology plus more general mathematics. It's just that what I learned at school is a fragmented knowledge system, which needs to be re-strung into a knowledge network.
This is a bit like the Rubik's Cube I played a few years ago. Although I haven't played for a year, I can't remember the speed (not fast), but the principle will never be forgotten (positive operation+reverse operation = unchanged), so I just need to follow the principle to fully recover.
Isn't TRIZ an application of first principles, such as functional analysis of object fields?
Principle 5, as a reminder to analyze the problem, tells us whether the step of problem definition is done properly, which is the same as TRIZ will give many possible solutions. If there is only one answer, it may be the first one that comes to mind, but it is not necessarily the best solution. I won't talk about it here.
These are the simplest principles for analyzing problems.
Before 20200902, I began to collect "small principles" in this regard. Today, the preface of the subway was updated, from simple to medium to complex problem methodology.
2020 1 1 13 I haven't updated my blog since September. I got up in the morning and quickly combed this long-standing article.
