· Foreword ·


After years of work, I have done a lot of different projects in different companies. These companies include tens of thousands of people, such as Huawei, including small private enterprises having 10 people, and work in government institutions . In these different enterprises, they all form some experience of project management, and they still have a success, so they still have more confident.

However, with time, I gradually found a problem, that is, I always feel that my project management knowledge is not very systematic. Every time I have a project management knowledge, I will only pass only, and I have not brought it to the face. And deeper levels, therefore actively conducted PMP learning.

The following is that after I study PMP in the system, combined with the original actual work, some summary and sentiments sublimated, I hope to give some small help to the needs of the friends.

·Background of the project·

Background of the Project

I have encountered a project when I work in a IVD company, and I received leadership arrangements.Responsible for research and development of a fully automated chemical instrument. The instrument is mainly measuring liver function, renal, blood sugar, blood lipids. The instrument needs to operate 7 * 24 to meet the actual requirements.

During the research and development, the product engineering sample has been developed, but during the trial operation, it is found that it will stop in operation for 1 hour. This issue will naturally have a big impact on the product, and the company’s leaders are also very concerned.

So the organization of the Organization of R & D team initiated a meeting, including colleagues in various major colleagues such as machinery, hardware, software, and crafts. The result after discussion is:

The machine’s colleague said: "There is no problem with the structural parts I design";

Hardware colleagues said: "There is no problem in my board";

Software colleagues said: "We checked the code, no such problem";

The colleague of the process said: "There is no problem in the assembly process."

After discussing a circle,Discover all parties deniny their own problems. Since everyone has no problem, then the instrument "see ghost", you will not run. The entire project is turned in a pause.



In this case, I use past experience and introduce it.First question responsibility system. Since I am a software technology, I finally delivered to the customer must be a software that can be run, so the person in charge first confirmed is a software team.

The software team is the first responsible person. If the software team can prove that the problem is not a software problem, it is suspected to be hardware, mechanical or process, and then contact the hardware, machinery or process team, further problem positioning.

Although I introduced the first question responsibility system, I actually act as the ultimate leader, or with the software team to participate in all positioning activities. In this process, I use my software expert’s ability and gradually discover a lot of software, and Solved one by one.

Among them, there is a more interesting solution to the problem: the same problem may come from a number of different reasons, and be sure to find one solution.

For example, this operation is 1 hour, it is 2 ~ 3, and after 1, it is found that the problem of running 1 hour will still exist, or may run 2 hours. So don’t doubt, the previous problem may have been solved, and now there is a new reason, you can continue to solve it, don’t take yourself in, and clarify your own ideas.

Finally, after a hard software problem, it is found that the instrument still has 2 hours of downtime, and sometimes it will be down for 1 hour, and there may be a deadlock.

At this time, it is necessary to make reasonable conjecture, is it possible to be a hardware FPGA problem, I will need to use it.Communication skillsNS. I immediately found the engineers of hardware FPGA, of course, you are welcome, because the previous hardware has already firmed "hardware no problem", if only doubts, let them solve the problem, I am afraid, I can’t accept it, this is the test.Project managerThe time!

I found that the engineer of hardware FPGA was: "Brothers, can help support this issue, the software brothers have no idea", hardware FPGA engineers have heard that they are helpless, naturally willful. If you say: "Brothers, you may have problems" So the communication soft skill here is also very important.

When finding a hardware FPGA engineer to help position the problem,As a coordinator, guiding software and hardware colleagues work together towards a big solution direction.Note: The software and hardware colleagues usually focus on their own technology, very much attention to overall solutions. Therefore, under my guidance, look at the software code and process, while licking the FPGA code, ultimately, our hardware FPGA’s colleagues, found that there is a problem with an interrupted trigger time in his code, follow his own There is no problem with the design, but once and the software, there will be an error when running together!

Finally, after the hardware FPGA’s colleague modifies the code, this bug finally solved! As a leader of the project, I finally loose!

When I solve this problem, I didn’t learn PMP, but as the old will succeed in the Sand, I solved the problem with my feelings and experience. But why can I solve this problem?

After learning PMP, there was a matter, just as described above, that is, my solution, now summarizing it:

Meeting -> (First Question Responsibility System) Team Articles -> Expert Judgment -> Communication Equity -> Guidance Conference.

Through these 5 steps, I think you can also become a helping team to solve the challenge!

"Recommended" to buy a sound, have you prepared everything? Some things that the rookie and Xiaobai have to understand (below)

The CD record is playing digital streaming media music, and the black glue / tape is despised with all digital music carriers, which is the contempt of the sound circle, and the circle often often because of the view Differential evolution into a lip gun. For the big burning of the "drizzle" budget, you can do one, you can buy a set of experiences, standing on a while, even if the speech is also a neutral attitude, and "Xiaobai" and "rookie" because of the qualifications Light and don’t dare, I can only look at the masters.

Now CD records, online digital music and black pasters are coexisting in the market, and no one is replaced, can only say who is the mainstream of today. Obviously, online digital music is the current mainstream, which is recognized. If you are interested, you can check the statistics of the IFPI (International Recording Industry Association). The proportion of entity music such as CD records, black rubber, tape, and the vast majority are audible enthusiasts in consumption. The record company will only be evaluated according to market demand, and it will be done under the premise of ensuring that there is a sales, money to earn, and there is a prerequisite for the factory is willing to order. As "small white" and "rookie", don’t be too tangled, there is an entity record feeling, buy a CD machine, or a black gum player, otherwise it is on the line streaming media music, or downloads the music document hard drive, buy a digital player, for the home Save the space of the record.

As for the black rubber record / tape such analog carrier, is it to use them equal to whether to hear the temptation? That is really not necessarily! If the recording method is a digital recording, then it is issued in the form of a black gum or tape, is this sound? " Also, if the playback system involves the processing flow of A / D, D / A conversion, the sound is "simming the taste" or "digital taste"? Or is it like a black glue / tape because the sound characteristic of the carrier itself? These problems, I think everyone should want to think about it.

Of course, the above despise chains are just one of them. In fact, there are also a variety of contempons in the circle of enthusiasts. For example, using electronic management power plazatics, use the Class Class Class Class D. Date D class Date Dlass D … This topic is going to start again, so you will not say it.

The sound of professional audio equipment is white boiling water, small tract, three-stage balanced?

There is always a group of enthusiasts in the sound circle like to take professional audio equipment to listen to music. The most common is professional amplifier, listening speaker, its first reaction is the sound of professional audio equipment, no tract, or even cost performance Higher saying, or mentioning a brand of a brand, the radio is being used. Those "rookie" did hear these adjectives, I was born in an instant. Is it better to buy these professional audio equipment? Small, real, restore the original appearance of the sound, feel the true meaning of music, the price is also cost-effective, I can’t wait to buy it right away! In fact, in our view, this has a certain degree of cognitive misunderstanding. Professional amplifiers are first in design to "easy to use". The so-called "easy to use" is convenient for transportation, installation, wiring, but also requires stability, not easy and bad, and the range covered by the professional field is also wide, stage, recording room, conference, background music system, theater, cinema, etc. Category, equipment will also be targeted for different applications. As for the sound quality, there is a significant difference between the brand and the brand.

Speaking of the listening speaker, in recent years, it is also a more popular product in the circle of enthusiasts. Of course, the listening sound of everyone is widely used in the recording shed, the radio is used to make audio programs. So the problem is coming again! Throughout history, Yamaha (Yamaha) NS-10 Studio is one of the most widely used monitor speakers, that is, representing the music from the second-hand market to NS-10 Studio to listen to music, you can feel music. The true meaning, feel the shock of music? If it is true, why didn’t you see Yamaha (Yamaha) NS-10 Studio is widely used in the fever circle? Not only, nor is it a frequent curve of all listening speakers that tend to be straightforward. If there is such a listening speaker, its frequency response is starting from the low frequency (such as 100 Hz) to the high frequency direction (to 20kHz) ) Rendering a slow drop process, the overall presence is tilt, such a state is not to belong to "three balance"?

Of course, the author is not to express the meaning of buying professional audio equipment to listen to music. After all, there is also a good product in professional audio equipment, but why Xiaobai or rookie do not blindly admire professional audio equipment. Of course, the final choice is still in the hands. Really to play professional audio equipment, you have to continue to learn in depth. When you figure out, then you are no longer a "rookie".

Don’t fall invert, walk into the magic

Inside the enthusiast I know, there are two people who have always made me paterse. The three major hardware of the player, amplifier and speakers added to 5 ~ 60,000 yuan, not to buy, but they are very reluctant to spend money to buy signal lines and speaker cable, only a signal line spent 20,000, Overall is almost equivalent to the three major hardware, even higher. In my opinion, this is a phenomenon of being inverted, walking into the magic, this kind of enthusiasts have been playing, how many equipment have been exposed, and its essence is also a "rookie".

I remember that one of the enthusiasts gathered, I met one of the above-mentioned enthusiasts. He also filed me with himself. I gave him this time: I don’t deny that the wire will affect the facts on the sound system, but your CD machine is around 8,000 yuan, but it is equipped with a wire of 20,000 yuan. If it is used 20,000 pieces of CD machine with a 3-kilocated wire, the total investment is not big, but I absolutely believe that the latter will be much better. After all, the difference between the 30,000 wire in the sound quality is not huge, but the difference between the sound quality between 20,000 and 8 thousand dollars is very large, and the CD machine belongs to the source, but also in the sound system. A very important device, it is definitely prioritized compared to the line.

What is the steps of the purchase? First get three major hardware, then consider the wire accessories

Say that there is another topic here, what is the step of purchasing a sound system? Which one, which one? In fact, most of the old enthusiasts will have a good grasp of the order. The overall thinking is: first get three major hardware, and then consider the wire attachment.

First, speaker. The speaker can be the final sound of the sound system, and its importance is the first, can’t be sloppy.

The speaker is not good, the front end is not much white, so you have to choose a high quality speaker inside the budget.

Second, players and amplifiers. The player belongs to the source of the sound system, and the quality of the sound is also an absolute shadow.

ring. The power amplifier follows, the status between the two is not blocked. Simply put, the power amplifier needs enough power and keeps low distortion to drive your speakers.

Third, wires and other accessories. The three major hardware are all equipped, and the wires (including: signal lines, speaker lines, power cords, etc.) and other accessories, after all, these equipment are far from speakers, amplifiers, and players. Three hardware.

Fourth, there are conditions, it is best to have an excellent independent audio-visual room. It has a separate audio-visual room to have a dream of enthusiasts. After all, there are independent rooms to reduce the impact on your family (your favorite music, your family can don’t necessarily like it), and the room on sound effects is very large, so there are conditions The old enthusiasts not only need an independent audio-visual room, but also specially invite people to do acoustic design. Of course, to say that these seems to be a bit far from today’s topic, it has exceeded the "small white" and "rookie" accepted.

Perhaps some people will say this after reading this topic: play audio, understanding the sound is that the radish green dishes have love, don’t need this online, don’t put your subjective awareness to others, I like it. Ok. This is actually there is no problem. After all, it’s just like the article, the money is in your hands, and the final choice is still self-contained, and it can accept it.

But if you change a problem, today’s audio equipment is indeed inconvenient, especially since the outbreak of the epidemic, with the price of raw materials and parts, the price increase information of the audio equipment is followed. The primary essential condition for buying sound is money, and the majority of consumers are not everyone is rich, and they often need to think twice before spending money, and do more ready to work, and always spend out. It is because of such a starting point, I simply organized this topic article, the content is mainly by telling some personal experiences and truth, plus some small suggestions. I don’t dare to say that these recommendations can be accepted by each consumer, and it is not possible.

Whether it is "small white" or "rookie", I like audio, interested in the audio, also collected a variety of information, often there is a strong consumption desire, but because of the lack of experience, the high hands are low, easy to "step on "I just want to pass these personal experiences, truth and recommendations to give" small white "" rookie "a certain guiding role.
