2. Management organization

(1) Management measures
  • EXV Show, as technology companies developed enterprise standards, product development, production, installation and provide the basis protection.
  • Product traceability. Each product has a complete assembly wasted cards and debug test cards filing, the issue of quality to provide traceability to facilitate companies adopt pertinent measures for improving things.
  • Have a strict raw material storage and product delivery inspection system, and ensure that there are no quality problems in use of raw materials, substandard products not manufactured, product design drawings installed in strict accordance with the requirements and the preservation of the quality of the corresponding records.
  • Apparatus for measuring quality inspection center for specialized management regularly scheduled seized, and internal calibration, measurement failure to use equipment from the scene.
  • Implementation of the "three persistences" principle. That is no reason check left off, and those responsible for other operators did not receive education left off, improved measures are put into effect left off.
  • The company attaches great importance to the training of staff. To give lectures on the methods of teaching staff every staff safety and quality of the education and awareness of operational skills training to employees through training before they can be for posts.
  • EXV Show, as technology companies attach great importance to product after-sales service. Companies have full-time After-sales Services personnel, can quickly and effectively deal with customer advice, the quality of opinions and complaints.
(2) Quality control procedures
  From the design, procurement to purchase testing, inspection process, the ultimate test to staff training, quality OIA, services, statistics and other 20 areas of operation in strict accordance with the quality standards and ensure the continued quality of the product, and stability.
(3) Quality control staffing
  Quality System of Quality Supervision, Inspection Center as a functional department is responsible for company-wide quality management, including the process of order and raw materials into the plant inspection, the quality control of production processes, products settlement testing, quality system documentation preparation and implementation, supervision and after-sale service , the collection of information and user feedback. Quality inspection departments managers responsible for the day-to-day work of departments. In the design, procurement, production, assembly, and other key sectors with rich professional experience in the establishment of a full-time quality controllers and other departments to establish a part-time examiner, and regularly test their quality of professional training and evaluation.

4. Installation steps and focus

1. Construction process

According to the implementation of the project, the entire project process can be divided into:
Phase I: Needs analysis stage of investigation (including application requirements, process Survey)
Phase I: The design phase (including hardware and software system design)
Phase III: Project implementation phase (including all hardware and software systems installed)
Phase IV: Testing the FBI stage (including all subsystem testing and the entire system of the FBI)
Phase V: System run on trial basis (including trial operation and system adjusted)
Phase VI: System maintenance phase (including the formal operation and system maintenance)
The progress of the project from the list can see, after the signing of the contract, will immediately begin ordering equipment, construction site investigation, the installation of equipment in the equipment arrived, fully installed as far as possible in parallel, in order to minimize the construction period.
Installation steps:
1. opening inspection: According to the inventory list of goods one by one, fill opening inspection report.
2. Hardware and electrical testing: careful observation of light, if a hardware error, filling in the report.
3. Complete hardware connections: the system in the correct installation of various equipment boost, and other external connectivity equipment.
4. The completion of the installation of the software: the control of the operating system software installed and tested.
5. Identify and software system configuration: Application of discussions with customers demand determine the parameters set software.
6. Functional Test System product design consistent with the program.
7. Complete installation of the report.
8. Discussion of the remaining issues.

2. Construction points

  If the large-screen display system equipment at the scene in the process of installing equipment failure, engineers and users will be engineers with fault of the equipment necessary for maintenance and replacement of hardware, equipment returned to normal. And users with maintenance of the equipment failure is the purpose of these engineers gradually through practice site maintenance with the practical experience.
  System hardware and software installation. We strictly follow the implementation of plans to complete the arrangements for system hardware, software installation, completed the report after completing the installation.
  EXV engineers will do the installation process user's system and network administrators for each a brief description of the installation process, after the installation of the system and network administrators to manage the system simple site training, so that administrators can complete most the basic system and network management tasks.
  Systems with customers to discuss the implementation of the problems encountered, and system implementation to sum up, to see whether there are remaining issues to resolve pending further follow-up, follow-up work out the time schedule to resolve.
  Developed complete installation files, such as hardware configuration map, the physical and logical network maps, network equipment configuration parameters, database parameters.

3. The stage results and acceptance procedures

  In order to achieve the desired objectives, the project plan should be implemented fully optimized parallel to the work carried out in parallel as much as possible, but also give full consideration to the possibility of scheduling some time to work objectively is not shortened, or shorten after seriously affect project quality, compressed project cycle premise is to guarantee the quality of the works.
  Acceptance of the system when my company transferred to the customer units and associated technical and log files. Specific details include: system management, configuration; system and attention to the day-to-day operation and maintenance matters; system hardware, application software maintenance attention to day-to-day matters, system design program book.
  Project documentation including: equipment inventory, installation documents, process records, acceptance records, running records, as well as relevant technical information, such as the connection graph, configuration files, and so on. And for the customers and staff responsible for the technical unit responsible for all aspects of business.
  The above schedule is under contract and technical requirements of their own long-term experience in the development of that plan, the actual schedule will be planned in the list after the two sides signed a contract mutually agreed by the two sides reached. Our final implementation plan to the two sides also confirmed the implementation plan shall prevail.
