I have been working in the field of functional safety for many years and have witnessed the functional safety of high-speed railways and urban rail transit blooming from sporadic to widespread. I am also working hard to open up a new era of functional safety in the automotive industry. Along the way, I have discovered that once I get into a pit, it is as deep as the sea. There is a point of no return, but make peace with what you have come to. If you want to do it, you must be a functional safety practitioner with a posture, but it is meaningless just for one person to have a posture. It is really good if everyone is good. I want to pull you to have a posture together.
Functional safety practitioners, this scope is a bit broad and can kill a group of people with one stick, because it refers to all practitioners related to functional safety, including development, testing, functional safety analysis and management, certification parties, etc. Looking back at the revolutionary road of functional safety, which functional safety practitioner does not have tears of bitterness behind his back, convincing leaders over and over again about the cost investment and time investment in the early stage of functional safety; arguing over a functional safety issue time and time again, and they will die of old age. Don’t communicate with each other; it’s easy to be compromised if you’re not careful, but a few small functional safety accidents are enough to turn you into a sinner for the ages. Therefore, being a functional safety practitioner with attitude is a required course for every functional safety practitioner.
To be a functional safety practitioner with attitude, you only need four maxims:
No guilty conscience, no fear, no compromise, no shame
1. Not guilty
The first is not to feel guilty in terms of ability.
To forge iron, you need to be hard-working. As a functional safety practitioner with a high profile, deep knowledge reserves and rich experience are essential. Otherwise, what can you do to fight against this impetuous society? ! Not to mention that you are proficient in functional safety standards and can recite them backwards and forwards, it is not enough. From theory to practice, you need to have a comprehensive accumulation and be able to integrate the knowledge system. Just like martial arts masters, they will not memorize moves by rote, but be flexible. use. As long as your knowledge accumulation reaches a certain level, your posture will naturally become elegant.
The second is not guilty in behavior.
Functional safety practitioners should never bury themselves in the code of conduct. They should not bury any hidden dangers in functional safety products, leave behind any defects that they have the ability to change but do not change, and do not relax any responsibility within the scope of responsibility because of laziness. A link, down-to-earth, step by step to complete every job.
2. Not afraid
Not being afraid here means not being afraid of power and convincing others with reason.
In any enterprise or organization, the top leaders’ top priority must be profit and cost-effectiveness. Functional safety projects cost much more and take much more time than traditional projects. Leaders often hope to save money, and for functional safety , their understanding is generally to
"spend the least money and get the safety certification certificate in the fastest time",
but it is understandable that leaders take this as their goal. As a functional safety practitioner, if you only take this as your ultimate goal The target is hopeless. Not only do you have to have more ambitious goals, you also need to not be afraid of pressure from leaders, convey the correct spirit of functional safety to them, and help them calculate the cost of accidents. Suggested reference cases are as follows:
In the major rail transit
accident
on July 23
, two trains collided,
killing
40
people,
injuring
172
people, interrupting traffic
for
32
hours and
35
minutes
, and causing direct economic losses
of 190
million yuan.
Automobile industry Unexpected acceleration accidents of Toyota cars in the United States.
In the ten years from
2000
to
2010
, as many as
89
people were killed due to unexpected acceleration of Toyota cars
. In addition,
57
people were seriously injured. There were
6,200
user complaints
. Toyota was eventually found responsible for the brake problems and
fined $
1.2
billion for concealing safety hazards, not including separate lawsuit damages.
3. No compromise
In terms of functional safety, there should be no compromise on principled issues.
In the actual process of the project, there are often various opportunistic attempts to test our bottom line. A functional safety practitioner with an attitude can never make any compromise on the principle issue of functional safety. This is the bottom line.
Many times, project time is tight, and functional safety is time-consuming and labor-intensive. At this time, time cannot be compromised;
Sometimes a design flaw is discovered late in the project, and modifications need to be made all over again. At this time, the current design cannot be compromised;
Sometimes the system is not perfect, the processes are not standardized, and the operation diagram is convenient. At this time, we cannot compromise on the status quo;
There are always some people in the project who want to take shortcuts, and you cannot compromise on these views
...
In short, a functional safety practitioner with good attitude should be a good young man with three correct views and independent thinking. He has his own bottom line when it comes to functional safety issues and can stick to his own bottom line.
4. Shameless
Shameless means don't stick to face.
Functional safety practitioners with an attitude should point out problems promptly and bravely when they find them, and hit the nail on the head, instead of being vague and vague. Even though the "shameless" arguments on functional safety issues may not be so harmonious, and sometimes even lead to explosive verbal battles, the result of "shameless" will be that the functional safety of the product will be more complete.
The reason why "shameless" is chosen as the symbol of the posture of functional safety practitioners is because this word is too real and beautiful. It should not be a derogatory term. It is the authenticity after putting aside the external hypocrisy and vanity, expressing the truth. Rather than wearing a disguised mask to be a good person, this is the highest state that an excellent functional safety practitioner with attitude needs to achieve.
Since ancient times, the best secret books in the world have been short and concise, requiring extremely high understanding.
