Management is practice. Its essence is not knowing but doing. Its test is not logic but results. Its only authority is performance.
—— Peter F. Drucker, Management: Tasks, Responsibility, Practice
Management is a kind of practice. Its essence lies not in knowledge but in behavior; its verification is not in logic but in achievement; the only authority is achievement.
- Peter Drucker "Management Practice"
How to comment on the quality of electrical design or the level of design? The only answer is that achievement! If the drawings you designed are handed over to the workers, and the workers do not allow the machine to move normally after completing the wiring according to the drawings, no matter how beautiful and beautiful your pictures are, it will not help.
Why does electrical design need to be standardized?In fact, standardization is only a means, and its purpose is to develop around achievements.
In the design, we all need to pay attention to the design cycle and the output of the design. With the stipulated environment and the specified working hours, we can complete the products that meet the production and other departments' requirements for drawings and data. To achieve the above-mentioned goals, if the design environment or design process is arbitrarily changed, or the operating methods or operating conditions vary from person to person, products that meet the above objectives must not be produced. Therefore, the work flow, work method, and operating conditions must be specified and implemented to standardize.
The four major goals of standardizationStandardization has the following four main purposes: technical reserves, improve efficiency, prevent recurrence, education and training. The role of standardization is mainly to save the technology and experience accumulated by the members of the company through documents, without losing the entire technology and experience due to the flow of people. How much the individual knows how much the organization knows, that is, the individual's experience (wealth) is transformed into the enterprise's wealth; but because of the standardization, even if each job is changed for different people to operate, it will not be efficient and There is a big difference in quality.
If there is no standardization, when the old employee leaves the company, he puts all the valuable experience of the corresponding methods, work skills, etc. that have had problems in his head, and the new employee may repeat the previous problem, even if he has been taught at the time of the handover. However, it is difficult to remember completely with memory. Without standardization, different masters will bring out different apprentices, and the consistency of their work results can be imagined.
Standard setting requirementsMany companies have this or that standard, but careful analysis, you will find many standards have operational problems such as poor, unclear, for example, "make symbols to regulate some". What is a specification? Not operational. In fact, the formulation of a good standard is required, and it is necessary to meet the following six points:
1. The target points. Standards must be faced with the goal that compliance with standards will always produce products of the same quality. Therefore, words and contents unrelated to the target should not appear.
2. Display the cause and result. For example, "Create a line type according to design requirements." This is a result and it should describe what the design requirements are. If it is stated as "Create a variety of line types according to the actual diameter and color physical information of the actual wire used", it will be more clear.
3. accurate. To avoid abstraction, "make symbols to regulate some", what is the norm? It is not appropriate to use vague concept words. You need to add a “multiples of 2.5mm between two connection points, usually 2xâ€.
4. Quantitative - specific. Every person reading a standard must be able to interpret the standard in the same way. The above 2.5mm is a specific quantification.
5. reality. The standard must be realistic and operational. The standard operability is very important.
6. Revision. Standards must be revised when needed. In a good company, work is conducted in accordance with standards, so the standard must be up-to-date and reflect the correct operating conditions at that time. There will never be a perfect standard. For example, when parts or materials have been upgraded, the standard will need to change the design environment of the materials.
Elecworks let standardization landDifferent companies have different requirements for the level of detail of the standardization. Here are some general standardization requirements.

Standardization is one of the two major wheels for enterprises to improve their management level, and is an important means for companies to pursue efficiency and reduce errors. For example, standardization is analogous to creating an abrasive tool that allows all work to be molded inside the tool, regardless of whether it was originally a circle or not. After entering the tool, the output is valid.
