System alteration risk control method based on business

Abstract

The invention discloses a system alternation risk control method based on business. The system alternation risk control method comprises the following steps that firstly, all business procedures of a system are acquired; secondly, the business impact factors of all the business procedures are extracted; thirdly, the alternation risk values of all the business procedures are calculated according to the impact coefficients of the business impact factors; fourthly, the alternation risk values of all the business procedures are integrated, and the system alternation risk value is obtained. According to the system alternation risk control method based on business, due to the fact that the business impact factors of all the business procedures are extracted, the alternation risk values of all the business procedures are calculated according to the impact coefficients of the business impact factors, the alternation risk values of all the business procedures are integrated, the system alternation risk value is obtained, and the alternation risk calculation is carried out on all the business procedures with the business as the breakthrough point, the system alternation risk value is visually and accurately worked out, and the controllability of system alternating is greatly enhanced.

Description

technical field [0001] The invention relates to a software system update control method, in particular to a business-based system change risk control method. Background technique [0002] Risk analysis is the evaluation and measurement of risk impact and consequences, including qualitative analysis and quantitative analysis. Among them, qualitative analysis is the process of assessing the impact and possibility of identified risks, ranking them according to their possible impact on project objectives. Its role and purpose are: to identify specific risks and guide risk response; to rank risks according to their potential impact on project objectives; to determine the overall risk level of the project (Overall Risk Ranking for the Project) by comparing risk values ​​(Risk Scores). Quantitative analysis is to quantitatively analyze the probability of each risk and its consequences on project objectives, and also analyze the degree of overall project risk. Its role and purpose...

AI Technical Summary

Problems solved by technology

The functions of the system modules are not directly related to the business. When developers realize the requirements, they are often unable to accurately predict the risks caused by code changes in a short period of time due to the limitations of their technical level and familiarity with the system.

[0011] 2) Lack of version risk control

Because the project cycle is short, the time to obtain effective data is short, and when the software system is changed and upgraded, a large number of codes, configurations, and parameter changes are involved. The business impact caused by the version, and the comparison with the historical change version data, cannot evaluate the development design quality

[0012] 3) Lack of business-level risk assessment

At present, the risk assessment of the system is limited to a certain node, or a specific interface, which cannot be directly mapped to a specific business on the system, and it is impossible to clearly understand which users are affected by system changes, so that it is impossible to concentrate resources on high-risk businesses. monitoring

[0013] 4) High dependence on people

At present, the system is changed and upgraded, and the system is modified accordingly. Ordinary developers / testers cannot understand the scope of influence of the change and the corresponding risks, and can only understand the code level, not very clear about the impact on online business, or Senior personnel are required to combine business and system architecture with comprehensive analysis, and rely on the personnel's technical level, system familiarity and comprehensive business knowledge
