After-sales service
Project building is a complex, long-term technical service. In order to fulfill the system service earnestly, the following principles are prepared as the main principles of instruction:
Principle of response timeliness
The Technical Service Department and Customer Service Center of the YUKE Technology will undertake the quick response of the construction of this project, and provide technical consultation service in time.
Principle of normative service
Our implementation engineers, technical supporting engineers and maintenance engineers do not only have professional technical skills, but also have been certified by the training about the company’s customer service specifications. They provide customer service in strict accordance with our company’s customer service specifications.
Principle of high efficiency in solving problems
The principle of the high efficiency in solving problems refers to the quick positioning and problem solving through the professional skills of the site supporting engineers.
Process of customer service response
“Customer-centricity” is the important business philosophy of the YUKE Technology. In order to practically implement this philosophy, and to ensure the timely response to and standard service for customers’ problems, the company has established a scientific, reasonable customer service response system. The Customer Service Center of the YUKE Technology will provide technical consultation services for customers.
Periodic preventive system maintenance
The status report is required for periodic inspection. In the report, there shall be the detailed error recording of each part of hardware, and measures can be adopted as soon as possible accordingly to eliminate hidden faults. The engineers of our company’s Technical Center periodically implement remote login by the Internet to fulfill 24-hour automatic reporting and tracking against problems. Then, these engineers can provide timely maintenance and repair based on the relevant results. Periodic equipment testing and inspection are implemented to find out hidden faults, and to eliminate them as soon as possible.
Rapid site service
If there is any system failure diagnosed in the customer’s system that cannot be solved by means of telephone/email, remote dial-in analysis, etc., our site engineers will immediately take along the corresponding system tools and software, and head for the site for emergent maintenance. We promise that we will respond to customers within 24 hours after the system failure, and will arrive at the customer’s site within 3 working days in case of any site maintenance.
Periodic visit and communication
During the operation of the customer’s system, we will adopt the method of designating special personnel to implement visits and communication regularly or irregularly to investigate the project implementation and maintenance, listen to customers’ opinions, solve customers’ problems at site, as well as test and optimize systems at site. In this way, we can find out system problems or hidden faults, eliminate hidden faults in advance, ensure safe, stable system operation, and fulfill the quality assessment of the system.
The above customer service response methods are not isolated or unrelated to each other. However, supported by the organizational structure of the Customer Service Center of the YUKE Technology, multiple flexible service modes permeate into, and are combined closely with, each other, forming a complete, unified fault response system for customers’ service. This system has been experienced practically in many large-scale working projects, and has been considered as the efficient, feasible and optimal fault response method.
