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.
