System defect issues refer to issues raised by users that are related to validation and change.the corresponding parts of system, which must go through stages such as sending, diagnostics, confirmation, processing and response. After decision, send feedback about decision to User. The specific submission process is as follows:

(1) Submit an application. When an application system user discovers a problem that belongs to category of system defects, he fills out a system defect report form and submits it to support staff.

(2) Analysis of problem. The help desk receives list of issues submitted by user and organizes appropriate personnel to analyze and evaluate issues described in list of issues and determine type of issue (technical issue, business issue, or operational issue). If it's a technical issue, please send it to service team to provide specific opinions and suggestions for resolving existing issues; if it is a business issue, send it to maintenance staff for processing; if it is an operational problem, you can organize appropriate personnel to explain problem to person who suggested it and report system defect.

4 Emergency response measures

A certain XX Technology Co., Ltd. has developed a detailed plan and emergency response plan for this project, and whole process is strict and orderly. However, in process of servicing, it will be difficult to completely avoid unforeseen situations. Below, we will analyze in detail sudden risks of project implementation and develop appropriate measures to prevent and deal with various emergencies, and provide a complete emergency treatment process.

4.1 Basic avaemergency procedures

Procedure for handling emergencies in service department

4.2 Preventive measures

Given various risks that may occur during door-to-door service process, a certain XX Technology Co., Ltd. summarized her own service experience and formulated a number of preventive measures for some possible situations. Examples are as follows:





Application software

Failed to start program executable

Staff working from home preparing all kinds of programs in advance to install maintenance software

Reinstall after backing up software data files

The software closes due to an abnormal error while opening or running

The access staff is ready to install programs, optimize operating system and fix software, as well as destroy virus software

Identify cause of error, back up your data, and take necessary corrective action

Network or server

B/S fabric system network traffic abnormal or server login abnormal

Determine if server is abnormal or prepare anti-virus software

Check network traffic, if traffic is abnormally low, report it to network service provider for repair, and if traffic is abnormally high, check and kill virus

4.3 Emergency emergency response strategy

The emergency system operation and maintenance plan is to quickly respond and fix failures or failures that seriously affect business, such as downtime, data loss, business interruption, etc., and restore business system in shortest possible time terms. minimize losses. In process of system maintenance, it will be difficult to completely avoid occurrence of emergency situations, in this regard, a certain company XX Technology Co., Ltd. developed a perfect emergency response strategy.

System inspection personnel should regularly check operation of each hardware device and application software, and at same time perform well daily incremental data backups and regular full backups. When reporting detected problems to responsible persons at all levels, appropriate resources should be coordinated to analyze root causes of problems, identify solutions and workarounds, and prevent greater impacts. After problem stabilizes or is completely fixed, a problem report should be generated to avoid similar major accidents in future.

When reporting issues to responsible person, coordinate appropriate resources to analyze firstcauses of problem, identifying solutions and workarounds, and avoiding more serious consequences. After problem stabilizes or is completely fixed, a problem report should be generated to avoid similar major accidents in future.

A XX Technology Co., Ltd. not only has experienced technical support engineers, but has built a common knowledge base based on years of customer service experience, including contingency strategies for various common technical failures and emergencies. Upon learning of an emergency, technical support personnel can immediately retrieve appropriate emergency strategy from knowledge base and provide appropriate solutions based on user's specific situation, and then provide support by phone, email or onsite at earliest opportunity. time A way to help users solve problems and do their best to reduce impact of emergencies on users' daily applications.



Emergency Strategies

Equipment broken

Damage to project block equipment

If there is no data loss, data security is guaranteed, and it is recommended that project module replace related hardware.

Operation failed

Strengthen training efforts, understand effect of training, check work level of operators, and remind them to take precautions.

If an operation error does not result in immediate results or data is not lost, ensure data security, otherwise contact relevant departments to resolve problem. Pay attention to safety precautions

Configuration lost

Tutorial focuses on setup methods and steps before use, and specifically reminds you to act before use

Send maintenance and training personnel to site for reconfiguration and patient explanations.

Data loss

During training, it is emphasized that during use it is necessary to regularly back up important data. During daily maintenance, on-site maintenance personnel will back up data in real time and keep users informed.

Coordinate with relevant departments to make correction. If it cannot be corrected, please submit a report explaining reason.
